Prefrontal executive function syndromes in children.
"Executive function" is a term describing the processes required for conscious control of thought, emotion, and action that are central to the management of one's day-to-day life. Executive function is subserved by the prefrontal cortex and related subcortical structures. Disorders affecting the prefrontal cortex-subcortical system are numerous and heterogeneous, but contemporary research has b...
متن کاملA functional neuroimaging study of motivation and executive function.
Executive functions, such as working memory, must intersect with functions that determine value for the organism. Functional imaging work in humans and single-unit recordings in non-human primates provide evidence that PFC might integrate motivational context with working memory. With functional magnetic resonance imaging (fMRI), we addressed the question of motivation and working memory, using...

متن کاملPrefrontal-Thalamic Anatomical Connectivity and Executive Cognitive Function in Schizophrenia.
BACKGROUND Executive cognitive functions, including working memory, cognitive flexibility, and inhibition, are impaired in schizophrenia. Executive functions rely on coordinated information processing between the prefrontal cortex (PFC) and thalamus, particularly the mediodorsal nucleus. This raises the possibility that anatomical connectivity between the PFC and mediodorsal thalamus may be 1) ...
متن کاملPrefrontal cortex and neural mechanisms of executive function.
Executive function is a product of the coordinated operation of multiple neural systems and an essential prerequisite for a variety of cognitive functions. The prefrontal cortex is known to be a key structure for the performance of executive functions. To accomplish the coordinated operations of multiple neural systems, the prefrontal cortex must monitor the activities in other cortical and sub...
