Following sleep deprivation, there is increased activation of the left inferior frontal gyrus and the bilateral parietal lobes. This information suggests that divided attention tasks require more attentional resources than normally required by a non-sleep-deprived person. [5]
Two main frontal areas have been implicated in the dream process. The first involves the deep white matter of the frontal lobes (just above the eyes). The main systems at work here involve the mesolimbic and mesocortical dopaminergic pathways. There are connecting fibres that run between frontal and limbic structures.
Simplified diagram of frontal cortex to striatum to thalamus pathways. There are five defined frontostriatal circuits: motor and oculomotor circuits originating in the frontal eye fields are involved in motor functions; while dorsolateral prefrontal, orbital frontal, and anterior cingulate circuits are involved in executive functions, social behavior and motivational states.

Individuals with frontal lobe damage have deficits in temporal context memory; [6] source memory can also exhibit deficits in those with frontal lobe damage. [7] It appears that those with frontal lobe damage have difficulties with recency and other temporal judgements (e.g., placing events in the order they occurred), [8] and as such they are unable to properly attribute their knowledge to ...
Some examples of learning disabilities in the brain include places in Wernicke's area, the left side of the temporal lobe, and Broca's area close to the frontal lobe. [5] Also, cognitive abilities based on brain development are studied and examined under the subfield of developmental cognitive neuroscience. This shows brain development over ...
BA10 is a subdivision of the cytoarchitecturally defined frontal region of cerebral cortex. It occupies the most rostral portions of the superior frontal gyrus and the middle frontal gyrus. In humans, on the medial aspect of the hemisphere it is bounded ventrally by the superior rostral sulcus. It does not extend as far as the cingulate sulcus.
The noted probable location of the SAS is in the frontal lobes, [1] more specifically in the prefrontal cortex. [10] This follows in understanding that the frontal lobes provide a framework to reach attainable goals. The dorsolateral region of the frontal lobes is involved in thinking and language, and organizes mental representations of ...
Frontal lobe damage often disrupts this process, preventing the retrieval of information and the evaluation of its output. [ 21 ] [ 22 ] Furthermore, researchers argue that confabulation is a disorder resulting from failed "reality monitoring/source monitoring" (i.e. deciding whether a memory is based on an actual event or whether it is ...
