Working Memory in the Prefrontal Cortex
The prefrontal cortex participates in a variety of higher cognitive functions. The concept of working memory is now widely used to understand prefrontal functions. Neurophysiological studies have revealed that stimulus-selective delay-period activity is a neural correlate of the mechanism for temporarily maintaining information in working memory processes. The central executive, which is the ma...
متن کاملEffects of systemic and intra-prefrontal cortex administrations of ethanol on spatial working memory in male rats
Introduction: Ethanol can induce a wide spectrum of neurophysiological effects via interaction with multiple neurotransmitter systems and disruption of the balances between inhibitory and excitatory neurotransmitters. Prefrontal cortex is involved in cognitive process including working memory and is sensitive to ethanol. Present study investigates the effects of intraperitoneal (i.p.) admini...
متن کاملThe prefrontal cortex and working memory: physiology and brain imaging.
Sustained activity has been recorded in the prefrontal cortex during working memory tasks. First, we compare the anatomical distribution of this activity in humans and monkeys. Then, we show that it reflects many factors, maintenance of the items presented, preparation for the response, transformation of the items during the delay, task rules and task goals. Finally, we point out that sustained...
متن کاملPrefrontal cortex and basal ganglia contributions to visual working memory.
Visual working memory (VWM) is a remarkable skill dependent on the brain's ability to construct and hold an internal representation of the world for later comparison with an external stimulus. The prefrontal cortex (PFC) and basal ganglia (BG) interact within a cortical and subcortical network supporting VWM. We used scalp electroencephalography in groups of patients with unilateral PFC or BG l...
