WebAbstract Alterations in cortical parvalbumin (PV)-containing neurons, including a reduced density of detectable neurons and lower PV levels, have frequently been reported in the dorsolateral prefrontal cortex (DLPFC) of schizophrenia subjects. WebNeurophysiological deficits in the left dorsolateral prefrontal cortex (DLPFC) have been described in positron emission tomography studies of schizophrenia and depression. In schizophrenia and depression this deficit has been associated with the syndromes of psychomotor poverty and psychomotor retardation, respectively. stars ut southwestern

WebMar 1, 2003 · In a neuropsychological study, Petrides 26 found that selective damage to DLPFC did not disrupt maintenance at a low load (relatively few items to be remembered), but as the load increased, impairments became apparent. It thus appears that DLPFC may play some role in maintenance in working memory, at least at high loads. The dorsolateral prefrontal cortex (DLPFC or DL-PFC) is an area in the prefrontal cortex of the primate brain. It is one of the most recently derived parts of the human brain. It undergoes a prolonged period of maturation which lasts into adulthood. The DLPFC is not an anatomical structure, but rather a … See more As the DLPFC is composed of spatial selective neurons, it has a neural circuitry that encompasses the entire range of sub-functions necessary to carry out an integrated response, such as: sensory input, retention in See more Schizophrenia Schizophrenia may be partially attributed to a lack in activity in the frontal lobe.
