Neurons that were selective for face-view typically preferred forward face-view stimuli (0 degrees and 30 degrees rotation). The neurons which were selective for forward face-view were also auditory responsive LY2835219 nmr compared to other neurons which responded to other views or were unselective which were not auditory responsive. Our analysis showed that the human forward
face (0 degrees) was decoded better and also contained the most information relative to other face-views. Our findings confirm a role for VLPFC in the processing and integration of face and vocalization information and add to the growing body of evidence that the primate ventrolateral prefrontal cortex plays a prominent role in social communication and is an important model in understanding the cellular mechanisms of communication.

“Whereas some studies suggest that alpha rhythm promotes information
processing in the human cortex (processing hypothesis), other studies suggest its involvement in an active cortical idling which prevents the interfering action of irrelevant information (idling hypothesis). In this study, this apparent contradiction was analyzed using a computing procedure which distinguishes phase-locked and nonphase-locked alpha response during Evofosfamide supplier the execution of a Fenbendazole complex event-related visual-motor
task. The electroencephalographies (EEGs) of 12 male volunteers were digitized (128 electrodes), band-pass filtered for isolating a wave, and event-related averaged during the execution of the visual-motor tasks. This procedure showed a phase-locked a response to stimuli and suppressed the non-phase-locked response. When EEG envelope of the a-wave was computed (Hilbert transformation) before the event-related average, the response of the alpha amplitude to stimuli was observed while the phase-locked a response vanished. Visual stimuli induced a short-lasting increase of phase-locked alpha activity and a long-lasting decrease of non-phase-locked alpha activity whose latency and amplitude changed with the cortical region (visual vs. parietal vs. frontal cortex), with the sensory-semantic information of visual stimuli, and with the tasks associated to them (comparing the alpha response to stimuli which were used for a visual-motor tasks with those passively observed). Alpha sub-bands around the individual alpha frequency peak showed a different phase-locked response. Finally, two early evoked potentials (C1-P1) showed a time latency similar to that computed for the phase-locked alpha response, suggesting that early evoked potentials are modified by the superposition of this alpha activity.
