Increasing the hydrophobicity of scyllo-inositol by the addition

Increasing the hydrophobicity of scyllo-inositol by the addition of two methoxy groups (1,4-di-O-methyl-scyllo-inositol) produced a derivative that stabilized Aβ42 protofibrils in vitro. Prophylactic this website administration of 1,4-di-O-methyl-scyllo-inositol

to TgCRND8 mice attenuated spatial memory impairments and significantly decreased cerebral amyloid pathology. These results suggest that Aβ aggregation can be targeted at multiple points along the kinetic pathway for the improvement of Alzheimer’s disease-like pathology. “
“Stem cells/progenitors are being discovered in a growing number of adult tissues. They have been hypothesized for a long time to exist in the pituitary, especially because this gland is characterized by its plasticity as it constantly adapts its hormonal response to evolving needs, under the control of the hypothalamus. Recently, five labs have reported the presence of adult progenitors in the gland and shown their endocrine differentiation potential, using different in vitro assays, selection methods and markers to purify and characterize these similar cell populations. These will be discussed here, highlighting common points, and also differences. Thanks to these recent developments it is now possible to integrate progenitors into the physiology of the gland, and uncover their participation in normal but also pathological situations. Moreover, experimental situations inducing generation

of new endocrine cells can Clomifene now be re-visited in light of the involvement of PI3K inhibitor progenitors, and also used to better

understand their role. Some of these aspects will also be developed in this review. “
“Neurons in the primary auditory cortex (AI) encode complex features of the spectral content of sound, such as direction selectivity. Recent findings of temporal symmetry in AI predict a specific organization of the subcortical input into the cortex that contributes to the emergence of direction selectivity. We demonstrate two subpopulations of neurons in the central nucleus of the inferior colliculus, which differ in their steady-state temporal response profile: lagged and non-lagged. The lagged cells (23%) are shifted in temporal phase with respect to non-lagged cells, and are characterized by an ‘inhibition first’ and delayed excitation in their spectro-temporal receptive fields. Non-lagged cells (77%) have a canonical ‘excitation first’ response. However, we find no difference in the response onset latency to pure tone stimuli between the two subpopulations. Given the homogeneity of tonal response latency, we predict that these lagged cells receive inhibitory input mediated by cortical feedback projections. “
“We investigated how physiologically observed forward suppression interacts with stimulus frequency in neuronal responses in the guinea pig auditory cortex. The temporal order and frequency proximity of sounds influence both their perception and neuronal responses.

Therefore, the gene products of PHIEF11_004 and PHIEF11_0010 are

Therefore, the gene products of PHIEF11_004 and PHIEF11_0010 are likely to be major components of the phage head subunit. PHIEF11_008 exhibits similarity to the genes for phage scaffold proteins found in several other phages including S. pyogenes phage 10750.2, Lactobacillus johnsonii prophage Lj965, and Staphylococcus aureus phage 80alpha. Moreover, the deduced size (23 446 Da) and pI (5.1) of the product of PHIEF11_008 is well within the size range (22 241–24 369 Da) and pI values (4.7) of the scaffold proteins of these other phages. For these reasons, it would appear that PHIEF11_008 specifies the scaffold protein required for the assembly of the head. The function of the remaining

genes within this module

cannot be assigned; however, the products of several of these ORFs have similarity buy SB203580 to proteins of unknown function encoded by other phages (Table 1). (3) Genes encoding proteins involved in tail subunit morphogenesis Epacadostat supplier (PHIEF11_0011 to PHIEF11_0020): PHIEF11_0013, PHIEF11_0015, PHIEF11_0016, and PHIEF11_0020 are proposed to be genes encoding the components of the φEf11 tail. They exhibit similarity to tail components of Lactococcus, Staphylococcus, and Enterococcus phages (Table 1). The tape measure protein of bacteriophage λ determines the tail length of the virion (Katsura & Hendrix, 1984; Katsura, 1987). In the φEf11 genome, PHIEF11_0019 has an HMM match (above the curated trusted cut-off) to the tape measure domain found in many tape measure proteins (TIGRFAM TIGR02675), and also overall similarity (blastp) to the tape measure proteins of Bacillus and E. faecalis Tolmetin phages (Table 1). The genes located between the major tail protein and the tape measure protein in many bacteriophages are involved in the formation of a tail initiator complex onto which the major tail protein can polymerize (Brøndsted et al., 2001). PHIEF11_0017 and PHIEF11_0018 show similarity to proteins of S. pyogenes and L. casei phages, which have unknown functions (Table 1). However, PHIEF11_0013, located upstream of the predicted major tail protein genes,

has high blastp identity to tail assembly proteins of other phages (Table 1, Fig. 1), suggesting that this may be the gene for the tail initiator complex in φEf11. Furthermore, in most bacteriophages, the genes located between the major head and the major tail genes are involved in the formation and connection of the head and tail structures (Brøndsted et al., 2001); therefore, by analogy, PHIEF11_0011 to PHIEF11_0014 may encode the proteins that serve a similar function. (4) Genes encoding lysis proteins (PHIEF11_0025 to PHIEF11_0030): The lysis module of the φEf11 genome consists of genes for a holin protein (PHIEF11_0025), an endolysin protein (PHIEF11_0026), a lysin regulatory protein (PHIEF11_0027), an amidase (PHIEF11_0028), a membrane protein (PHIEF11_0029), and a protein with a Lys M domain (PHIEF11_0030).

Towards a more complete genetic mapping of the secondary metaboli

Towards a more complete genetic mapping of the secondary metabolism in A. nidulans, we first cultivated a reference strain on an array of different growth media to uncover polyketides that were not previously linked to a gene cluster. This analysis revealed several compounds, including austinols, violaceols, arugosins and prenylated xanthones. Next, genetic links to these compounds were established by constructing and screening an A. nidulans mutant library

containing individual deletions of 32 putative PKS genes. The A. nidulans strain IBT29539 (argB2, pyrG89, veA1, nkuAΔ) (Nielsen et al., 2008) was used as the reference strain and for deletion-strain constructions. Escherichia coli strain DH5α was used for cloning. Fungal minimal Selleckchem Selumetinib medium (MM) was as described in Cove (1966), but with 1% glucose, 10 mM NaNO3 and 2% agar. Medium

for alcA promoter induction consisted of MM supplemented with 100 mM l-threonine and 100 mM glycerol as carbon source instead of 1% glucose. Polyketide screening media variants CYA, CYAs, YES and RT were prepared as per Frisvad & Samson (2004). CY20 medium consisted of CYA with 170 g sucrose; RTO contained RT with 30 g organic oat meal; and YE was made as YES but without sucrose. All media variants were supplemented with 10 mM uridine, 10 mM uracil and/or 4 mM l-arginine where appropriate. Individual PKS gene deletions were carried out as described previously (Nielsen et al., 2006), except that IDH activation the targeting fragments were assembled using Gateway technology (Hartley et al., 2000) (see Table S1 for PCR oligonucleotide and Fig. S2 for an overview of the procedure). The A. nidulans transformants were streak

purified and rigorously screened through three complementing diagnostic PCRs. Subsequently, the Aspergillus fumigatus pyrG marker was eliminated from all strains by selecting on 5-fluoroorotic acid medium before final verification by two additional complementing Nitroxoline diagnostic PCRs (see Fig. S3 and Table S2). All strains have been deposited in the IBT strain collection, DTU, ( The amino acid substitution of serine to alanine, S1660A, in ausA (AN8383) was created by USER fusion (Geu-Flores et al., 2007) according to the method described by Hansen et al. (2011). The allele was transferred to IBT29539 and the pyrG marker was eliminated by direct repeat recombination, creating strain IBT31032 containing only the desired point mutation. The strain was verified to contain the ausA-S1660A allele by sequencing (StarSEQ, Germany). See Table S3 for primer details. The gene, ausA, was PCR amplified by USER fusion (Geu-Flores et al., 2007) and inserted into both pU1111-1 and pU1211-1 (Hansen et al., 2011) creating pDH23 (gpdA promoter) and pDH24 (alcA promoter), respectively.

However, this has not translated to an increase in appropriate us

However, this has not translated to an increase in appropriate use of OTC NSAIDs; since ibuprofen has become available outside the pharmacy setting in Australia fewer people are using NSAIDs appropriately according to

the label. The quality use of medicines, in particular OTC NSAIDs, is becoming increasingly reliant on product labelling and the ability of consumers to understand and self-assess risk. In the midst of escalating healthcare costs globally, self-medication has become an increasingly important option in the symptomatic management of common conditions. Self-medication encourages consumers to take an active role in their health. Self-medication also provides positive outcomes at a societal level. The total annual

savings resulting from a move of 5% of prescribed medications to self-medication in seven European countries has been estimated to be in excess of €16 billion.[1] selleckchem However, the benefits of such self-medication practices are dependent upon their being undertaken responsibly. Global research, spanning 50 countries, into consumers’ attitudes towards key GSK1120212 ic50 aspects of self-care revealed that 95% of respondents were open to taking medicines to self-treat minor ailments.[2] Although safety and efficacy were deemed the most important product attributes, there was no clear global consensus on the way in which consumers can best ensure they use self-medication appropriately. Responsible self-medication is driven largely by two aspects of drug safety: the intrinsic characteristics of the drug and how the drug is used. Appropriate use

depends upon the availability of information, and how easily it can be used. Within the broader context of self-medication, pain relief occupies a prominent position. The analgesic paracetamol was the first drug to be made available over the counter (OTC) in modern times.[3,4] Today analgesics represent one of the leading self-medication categories. In 2008 in Europe consumers spent €4193 million on analgesics, amounting to 14% of the total non-prescription Depsipeptide market. Corresponding figures for the USA and Australia were €2021 million (US$2768 million; 16.5% of the total non-prescription market) and €223 568 (AUS$338 583; 8.5% of the total non-prescription market), respectively. Differences in regulatory classification systems in different countries mean that the term ‘OTC analgesic’ defines analgesics that are available within the pharmacy setting without a prescription as well as those that are available in general sales outlets where no healthcare professional intervention is readily available. In the Australian market paracetamol was first introduced in 1956 and has been available in general sales outlets for several decades.

Both closed (dichotomous and multiple-choice) and free text quest

Both closed (dichotomous and multiple-choice) and free text questions were employed. In July 2009, all YFVCs (n = 3,465) in EWNI were requested to complete the questionnaire. They were informed via a newsletter sent to YFVCs, on Angiogenesis inhibitor the NaTHNaC website, by email and for centers without known email addresses, by post. Email and postal reminders were sent out over a period of 4 months. Centers could complete the questionnaire electronically or print it and return it by post. YFVCs were informed that their responses would be analyzed in aggregate

and not linked to individual centers. Responses received by post were entered manually into Survey Monkey®. Results were exported into Microsoft Excel® for data cleaning, and data analyzed in STATA 9®. Free text answers were reviewed and grouped into new or existing answer categories. Data were analyzed using chi-squared tests, tests of proportions, and correlation coefficients. Where possible, responses reported in this current survey were compared qualitatively to those from the 2005 survey

with description of trends.17 Of the 3,465 YFVCs in EWNI in July 2009, a total of 1,454 centers responded to the questionnaire, with 1,438 centers completing the entire survey (41.5%). Response rates to individual questions ranged from 72.6% signaling pathway to 99.9%. The proportion of YFVCs completing questionnaires by geographic area (postcode area) was relatively uniform with 71.6% of areas having a completion proportion between 31 and 50%; 92.9% of responses were from YFVCs in England, comparable to the percent of all YFVCs in England

which was 90.0%. Most YFVCs that responded were General Practices (GP) (87.4%), and the person completing the questionnaire was usually the nurse responsible for the YFVC (41.8%) or a practice nurse working in the YFVC (43.0%) (Table CYTH4 2). Nearly all YFVCs (97.0%) had one or more nurses who administered YF vaccine; only 24.2% of centers had one or more physician administering YF vaccine (p < 0.0005). In addition, 97.0% of centers had nurses who advised travelers, whereas only 36.5% of centers had physicians advising travelers (p < 0.0005). A reduction was observed in the proportion of physicians administering YF vaccine (24.2% vs 48.7%) and advising travelers (35.5% vs 52.6%) compared to the baseline study. In the UK, nurses usually work under the specific direction of the lead physician. There was a wide range in the number of doses of YF vaccine given by YFVCs (Figure 1). The median number of doses was 50 per year [inter-quartile range (IQR) 30–75 doses], more than the baseline survey (median of 35 doses per year). The number of doses of YF vaccine given differed significantly by clinic type (p < 0.

Once the optimal IPTG concentration

Once the optimal IPTG concentration Doxorubicin concentration was obtained, additional cell-based assays were performed against a panel of known antibiotics of different chemical classes to obtain fold sensitization values [the ratio between the IC50 value (the concentration at which cell growth inhibited 50% compared with control) under noninduced condition and that of induced condition]. Based on the result of a time-course Sau3AI digestion (Fig. S1a, Supporting Information), the optimal partial digestion time was 4 h to generate DNA fragments of

appropriate size for library construction. Ligation mixtures were transformed into E. coli DH5α competent cells. Insert cloning efficiency analysis (Fig. S1b) indicated that the cloning efficiency for this library was 92%. To increase the randomness of the genomic DNA generated,

an alternative genomic library was constructed using a blunt-end producing restriction endonuclease (CviKI-1). The cloning efficiency of the CviKI-1-based library (termed Library C) was 90%. To screen for inducible growth inhibitory recombinant clones, transformants were grown overnight with chloramphenicol in the presence or absence of inducing IPTG. An example of screening plates and sensitive clones is shown (Fig. S1c). A total of 1500 confirmed IPTG-sensitive clones were Sunitinib manufacturer obtained from screening 250 000 individual transformants. Only 675 of the 1500 confirmed clones were sequenced. An example of inducer-dependent inhibition of growth of asRNA clone PT113 is shown in Fig. S1d. Plasmid DNAs from a total of 675 confirmed inducer sensitive clones were sequenced. It was determined that enough clones were analyzed because more analysis leads to identification of duplicates, suggesting that the

phenotypic screening process under the condition scheme is approaching saturation. Among the sequenced clones, 134 separate clones contained insert DNA sequences derived from and in antisense orientation to known essential genes based on PEC database (Table 1). For most of the essential genes targeted by asRNAs, multiple gene silencing asRNA constructs were discovered, with rplF gene (encoding 50S ribosomal subunit protein L6) being ‘hit’ the most (17 times) (Table 1). Because many essential genes engaging in a cellular process are usually clustered in an operon, many essential operons are targeted by a multitude of asRNAs, especially the operons for ribosomal protein genes. For example, rplN operon that contains 11 essential genes was ‘hit’ by 17 unique asRNAs (Fig. 1a, with two asRNAs not shown owing to space limit). On an individual gene level, four unique asRNAs were found to target fusA gene (Fig. 1b), while another four to target rpoC gene (Fig. 1d).

5% Tween 60 solution (Leslie & Summerell, 2006) For outcrosses,

5% Tween 60 solution (Leslie & Summerell, 2006). For outcrosses, the heterothallic female strains were fertilized with 1 mL of a conidial suspension (106 conidia mL−1) from male strains as previously described (Lee et al., 2003). All of the cultures were incubated under near UV light (wavelength: 365 nm) at 25 °C. For trichothecene (deoxynivalenol and 15-acetyldeoxynivalenol) analysis, the conidial suspension was inoculated in defined media containing 5 mM of agmatine (MMA) as previously described (Gardiner et al., 2009). Culture filtrates were extracted with ethyl acetate/methanol mixture (4 : 1, JNK inhibitor v/v) (He et al., 2007). The resulting trichothecenes were analyzed with a Shimadzu

QP-5000 gas chromatograph-mass spectrometer (GC-MS; Shimadzu, Kyoto, Japan) as previously described (Seo et al., 1996). To analyze zearalenone, mycelia of wild-type and transgenic strains that were grown in CM for 3 days, were subcultured into starch glutamate (SG) media and incubated for 7 days (Bacon et al., 1977). Culture filtrates were extracted and analyzed with a Shimadzu LC-6A HPLC as previously described (Kim et al., 2005a,b). The transcript level of TRI6 and ZEB2 gene was analyzed by quantitative

real-time PCR (qRT-PCR) as previously described (Lin et al., 2011). Briefly, total RNA was extracted from cultures in defined media containing 5 mM of agmatine at 4 days after inoculation (DAI) and in SG media at 7 DAI. The first strand cDNA was synthesized and qRT-PCR was performed. The Bleomycin solubility dmso transcript level of TRI6 in MMA and ZEB2 in SG media was quantified with appropriate primer pairs (Table S1). The housekeeping gene CYP1 (Broad Institute ID: FGSG_07439.3) was used

as an endogenous control for normalization. PCR was repeated three times with three biological replicates per run. To observe GFP and red fluorescent protein (RFP), mycelia were collected by centrifugation and fixed with paraformaldehyde in phosphate-buffered saline (4% w/v) (Seong et al., 2008). Meiotic chromosomes were stained with acriflavin as previously described (Raju, 1986). The perithecia were dissected in one drop of 20% glycerol on a microscope glass slide the and the rosettes of asci were gently flattened under the coverglass (Min et al., 2010). An Axio Imager 1 microscope (Carl Zeiss, Germany) was used for differential interference contrast and fluorescence observation (GFP excitation 470/40, emission 525/50; RFP excitation 546/12, emission 590). Nuclei stained with acriflavin were visualized with a GFP filter set. A blast search of the genomic sequence from G. zeae indicated that the fungus contains one copy of AreA homologue coding gene (areA, Broad Institute ID: FGSG_08634.3) with 85% sequence identity to the AREA-GF of G. fujikuroi (Tudzynski et al., 1999). The most conserved region of AreA homologues is a GATA-type zinc finger DNA binding domain. We employed a targeted gene deletion strategy to determine the roles of areA in G. zeae.

17–19 Ultimately, the purpose of the predeployment education is to prepare the trainees for the worse case scenario. In the event of a high-risk exposure, regardless of HIV status confirmation, immediate administration of PEP is warranted. With subsequent confirmation of HIV status through available Neratinib mouse testing, adherence to the PEP regimen is

paramount. Initiation of PEP should be immediate (ideally within 24 h) and continued for 4 weeks.20 In addition, the regimen chosen must balance potential toxicities against the level of exposure and the burden of disease (as characterized by the CD4 cell count, viral load, disease stage, and viral resistance) of the source patient. Unfortunately, VE-821 chemical structure PEP regimens are frequently discontinued due to intolerance of side effects, despite their known benefit in terms of reduction

of risk of HIV infection.8 Side effects can often be easily managed symptomatically with over-the-counter medications such as analgesics, antiemetics, and antimotility agents. The most basic PEP regimen recommended in the US Public Health Service guidelines includes either a combination of two nucleoside reverse transcriptase inhibitors (eg, zidovudine plus lamivudine or emtricitabine) or a nucleotide reverse transcriptase inhibitor with a nucleoside reverse transcriptase inhibitor (eg, tenofovir with either lamivudine or emtricitabine).8 Similarly, the WHO recommends zidovudine/lamivudine as the first-line therapy.21 The fixed dose combination of tenofovir/emtricitabine is generally better tolerated than zidovudine–lamivudine.18 Both guidelines recommend the addition of a protease inhibitor, with lopinavir/ritonavir listed Cell press as the first-line option, for more severe exposures.8,13 The 200/50 mg formulation of lopinavir/ritonavir is preferred because this does not require refrigeration. Alternate

protease inhibitors for the expanded regimen include ritonavir plus atazanavir or ritonavir plus darunavir.8,20 However, the ritonavir used in the latter two regimens requires refrigeration, which may not be feasible for traveling medical trainees. The newly available tablet form of ritonavir does not require refrigeration, in contrast to the gel capsule formulation. Efavirenz can be added to the basic regimen instead of a protease inhibitor, but this drug should not be used for PEP in pregnant health care workers or those who are planning to conceive during the month of treatment. In contrast, due to safety issues, nevirapine is contraindicated for PEP.

At this time, colonies formed by 10–15 yeast cells were selected

At this time, colonies formed by 10–15 yeast cells were selected under a stereomicroscope, picked up with a sterile toothpick and placed in 100 μL of sterile water. The cell suspension was spread on solid

potato-dextrose agar (PDA) medium and placed at 24 °C. After 4–7 days of growth, small colonies appeared (initial culture in Table 1). The fuzzy colonies were subcultured in liquid medium (10 mL of PDB) for 1 week (24 °C, 100 r.p.m.). The cell cultures were diluted to 500 cells mL−1, spread on PDA medium and cultured for 4–7 days (subculture 1 in Table 1). This procedure was repeated three times (subcultures 2 and 3 in Table 1). Strains showing 100% of fuzzy colonies after subculture 3 were defined as stable fuzzy strains and tested for their pathogenicity. Using the previous protocol, the ability of U. maydis, S. reilianum and M. penicillariae to produce solopathogenic strains was compared. For each species, teliospores from the different isolates were mixed to MG-132 ensure genetic diversity. One hundred sterile teliospores were analysed for each species. Cultures were performed on PDA medium with 0.5% charcoal for U. maydis, on PDA for S. reilianum and on both media by plate replication for M. penicillariae. The pathogenicity of the stable fuzzy strains was tested on the corresponding hosts for each species. Except for SRZS1 experiments where 40 plantlets were used, plant infection tests were carried

out on 10 plantlets for each strain. For S. reilianum, artificial inoculations were performed on maize plantlets (LMZ66; Limagrain, France) using Dynein a sterile syringe to inoculate the fungus in 10-day-old plantlets. A volume of 20 μL of cell suspension (107 cell mL−1) was injected into the stem, near the crown. Inoculated plants

were analysed 6 weeks postinoculation (w.p.i.) for PCR fungal detection on caulinar apices or for symptom observation (chlorotic spots on leaves, sorus formation). For U. maydis, foliar inoculations were performed on 3-week-old maize plantlets (LMZ66; Limagrain) and the formation of galls was observed 2 w.p.i. (Holliday, 1974). Inoculation of pearl millet (Sanyo; ICRISAT, Bamako, Mali) was carried out by infecting young floral spikelets and the symptoms were observed 5 w.p.i. (Wilson, 1995). Propidium iodide (Molecular Probes) staining was used to observe nuclei with a confocal laser scanning system (SP2 SE, Leica, Germany) equipped with an upright microscope (DM 6000, Leica). Cells from young 24-h cultures were fixed in 70% ethanol, rinsed with water, treated with RNAse A (65 °C, 10 min) and then incubated with propidium iodide, final concentration 0.1 μM, for 1 h before observation. DNA extractions were performed using the CTAB procedure (Gardes & Bruns, 1993). In planta PCR detection of S. reilianum was performed based on the amplification of the internal transcribed spacer (ITS) ribosomal regions using specific primers.

3; Table 3) The anterior intraparietal sulcus

is a core

3; Table 3). The anterior intraparietal sulcus

is a core component of the putative human mirror neuron system (Grafton & Hamilton, 2007). It is thought to contribute to the understanding of ‘immediate’ action goals, such as grasping to eat vs. to place in macaque monkeys (Fogassi et al., 2005), or taking a cookie vs. a diskette in humans (Hamilton & Grafton, 2006). In monkeys, the anterior bank of the intraparietal sulcus changes its connectivity and response patterns when the animals train to use tools (Hihara et al., 2006), enabling an integration of visual and somatosensory stimuli. This is argued to support tool use see more through assimilation of the tool into the monkey’s body schema (Maravita & Iriki, 2004), such that ‘tools become hands’ (Umiltàet al., 2008). However, human left anterior inferior parietal Venetoclax manufacturer lobule displays a specific response to observed tool use (as opposed to unassisted manual prehension) that is absent in monkeys (Peeters et al., 2009). This suggests that hominoid anterior inferior parietal cortex may be evolutionarily derived

to play a new role in coding the distinct functional properties of hand-held tools (Johnson-Frey et al., 2005; Peeters et al., 2009; Jacobs et al., 2010; Povinelli et al., 2010). The centre of anterior inferior parietal cortex activation reported here is somewhat posterior (−50, −36, 42 vs. −52, −26, 34) to that of Peeters et al. (2009); however, extraction of the volume of interest used by Peeters et al. (coordinates from Orban, pers. comm.) confirms that the same effect of stimulus is indeed present in this region. This response to increasingly complex Paleolithic toolmaking is consistent with the hypothesis that human technological evolution was supported, at least in part, by the emergence of enhanced neural mechanisms for representing the causal properties of hand-held tools (Johnson-Frey, 2003; Wolpert, 2003; Peeters OSBPL9 et al., 2009). The main effect in the prefrontal cortex was centred on the inferior frontal sulcus. In macaques, this region is heavily interconnected with the anterior

inferior parietal lobule (Pandya & Seltzer, 1982) and the parietal operculum (Preuss & Goldman-Rakic, 1989), in keeping with the co-activation observed here, and suggesting involvement in the integration of visuospatial and somatosensory information. In an fMRI study with macaques, there was activation in this area during the observation of actions (Nelissen et al., 2005). In contrast to more the posterior premotor cortex (F5c) where mirror neurons were originally recorded, the ventral prefrontal cortex also responded to abstract or context-free stimuli, including isolated hands, robotic hands and shapes (Nelissen et al., 2005), indicating representation and integration of actions at a relatively high level.
