Prefrontal cortical GABAergic dysfunction contributes to age-related working memory impairment.
Working memory functions supported by the prefrontal cortex decline in normal aging. Disruption of corticolimbic GABAergic inhibitory circuits can impair working memory in young subjects; however, relatively little is known regarding how aging impacts prefrontal cortical GABAergic signaling and whether such changes contribute to cognitive deficits. The current study used a rat model to evaluate...
متن کاملAge differences in prefrontal cortical activity in working memory.
Working memory (WM) declines with advancing age. Brain imaging studies indicate that ventral prefrontal cortex (PFC) is active when information is retained in WM and that dorsal PFC is further activated for retention of large amounts of information. The authors examined the effect of aging on activation in specific PFC regions during WM performance. Six younger and 6 older adults performed a ta...
متن کاملAge-related working memory impairments in children with prefrontal dysfunction associated with phenylketonuria.
The prefrontal cortex of the brain has been shown to play a crucial role in working memory, and age-related changes in prefrontal function may contribute to the improvements in working memory that are observed during childhood. We examined the developmental trajectory of working memory in school-age children with early-treated phenylketonuria (PKU), a metabolic disorder that results in prefront...
متن کامل[Hippocampal-prefrontal cortical circuit and working memory].
The study on learning and memory is one of the striking subjects in neuroscience today. In the cerebral cortex, it is has been proved that, the hippocampus, the prefrontal cortex and the hippocampal-prefrontal cortical circuit are important to working memory. In this paper, we review findings of the anatomical and electrophysiological characteristics of the hippocampal-prefrontal cortical circu...
متن کاملPrefrontal cortical involvement in visual working memory.
Studies of human amnesia provide evidence for a short-term memory store with information transfer to long term memory occurring within 60 s of sensory encoding. Human and nonhuman primate research has shown that maintenance of this short-term or working memory store is dependent upon frontal cortical activation, although the critical temporal parameters of frontal involvement throughout this 60...
