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.
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]
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.

These lobes are the Frontal lobe, responsible for conscious thought, Parietal lobe, responsible for visuospatial processing, the Occipital lobe, responsible for the sense of sight, and the temporal lobe, responsible for the senses of smell and sound.
The specific regions that show the most robust correlation between volume and intelligence are the frontal, temporal and parietal lobes of the brain. [ 10 ] [ 11 ] [ 12 ] A large number of studies have been conducted with uniformly positive correlations, leading to the generally safe conclusion that larger brains predict greater intelligence.
Developmental neuropsychology combines the fields of neuroscience and developmental psychology, while drawing from various other related disciplines.It examines the relationship of behavior and brain function throughout the course of an individual's lifespan, though often emphasis is put on childhood and adolescence when the majority of brain development occurs.

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.
Older children and adults with atypical neurology (e.g., people with cerebral palsy) may retain these reflexes and primitive reflexes may reappear in adults. Reappearance may be attributed to certain neurological conditions including dementia (especially in a rare set of diseases called frontotemporal degenerations), traumatic lesions , and ...
