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.
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 ...
This area is among the earliest affected by Alzheimer's disease, frontotemporal dementia, frontotemporal lobar degeneration, and is commonly involved at the start of temporal lobe seizures. [ 3 ] Cytoarchitectonic and chemoarchitectonic studies find that it contains at least seven subareas, one of which, "TG", is unique to humans.
It can also refer to the occipital operculum, part of the occipital lobe. The insular lobe is a portion of the cerebral cortex that has invaginated to lie deep within the lateral sulcus. It sits like an island (the meaning of insular) almost surrounded by the groove of the circular sulcus and covered over and obscured by the insular opercula.
The superior longitudinal fasciculus (SLF) is an association tract in the brain that is composed of three separate components. [1] [2] It is present in both hemispheres and can be found lateral to the centrum semiovale and connects the frontal, occipital, parietal, and temporal lobes. [2]
Brodmann area 9, or BA9, refers to a cytoarchitecturally defined portion of the frontal cortex in the brain of humans and other primates. Its cytoarchitecture is referred to as granular due to the concentration of granule cells in layer IV. [ 1 ]
BvFTD, which results from damage to the frontal lobes of the brain, mainly causes problems with behaviour and personality. PPA, when damage occurs to the temporal lobes on either side of the head ...
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.
