Numerous brain lesion and functional neuroimaging studies have suggested that the dorsolateral and frontopolar prefrontal regions are involved in complex cognitive processes subserving thought and memory. However, previously proposed functional subdivisions of prefrontal function have concentrated predominantly on posterior prefrontal cortex, including the dorsolateral, ventral, and medial regi...

The ethics committee that approved this work was mistakenly attributed to the Ardabil University of Medical Sciences due unintended miscommunication first author with corresponding authors. ethical permission is by Shahid Beheshti (ethics code: IR.SBU.ICBS.97/1036).

OBJECTIVE Behavioral and social impairments have been frequently reported after damage to the prefrontal cortex in humans. This study evaluated social perception in patients with prefrontal cortex lesions and compared their performance on a social perception task with that of healthy volunteers. METHOD Thirty-three patients with prefrontal cortex lesions and 31 healthy volunteers were tested ...

The purpose of this study was to investigate the effect of stereoscopic display alignment errors on visual fatigue and prefrontal cortical tissue hemodynamic responses. We collected hemodynamic data and perceptual ratings of visual fatigue while participants performed visual display tasks on 8 ft × 6 ft NEC LT silver screen with NEC LT 245 DLP projectors. There was statistical significant diffe...

BACKGROUND Late-life depression has been associated with cerebrovascular disease and especially with ischaemic white matter hyperintensities on magnetic resonance imaging. Neuroimaging and morphometric studies have identified abnormalities in the dorsolateral prefrontal cortex. AIMS To examine glial and neuronal density and neuronal volume in the dorsolateral prefrontal cortex in late-life ma...

Binge drinking or heavy episodic drinking is a high prevalent pattern of alcohol consumption among young people in several countries. Despite increasing evidence that binge drinking is associated with impairments in executive aspects of working memory (i.e. self-ordered working memory), processes known to depend on the mid-dorsolateral prefrontal cortex (Brodmann areas 46 and 9), less is known ...

Prefrontal cortex mediates cognitive control by means of circuitry organized along dorso-ventral and rostro-caudal axes. Along the dorso-ventral axis, ventrolateral PFC controls semantic information, whereas dorsolateral PFC encodes task rules. Along the rostro-caudal axis, anterior prefrontal cortex encodes complex rules and relationships between stimuli, whereas posterior prefrontal cortex en...

Abnormal gamma-aminobutyric acid inhibitory neurotransmission is a key pathophysiological mechanism underlying schizophrenia. Transcranial magnetic stimulation can be combined with electroencephalography to index long-interval cortical inhibition, a measure of GABAergic receptor-mediated inhibitory neurotransmission from the frontal and motor cortex. In previous studies we have reported that sc...
