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 ...
The posterior cortical hot zone includes sensory cortical areas in the parietal, temporal, and occipital lobes. It is the “sensory” cortex, much as the frontal cortex is the “action” cortex. When parts of the posterior cortex are damaged, whole modalities of sensory experience disappear from both waking and dreaming.
The basis for this discovery was the analysis of speech problems resulting from injuries to this brain region, located in the inferior frontal gyrus. Lesions to Broca's Area result primarily in disruptions to speech production. Damage to Wernicke's area, located in the lower part of the temporal lobe, mainly leads to speech reception disruptions.
Confabulation can occur with nervous system injuries or illnesses, including Korsakoff's syndrome, Alzheimer's disease, schizophrenia, and traumatic brain injury. It is believed that the right frontal lobe of the brain is damaged, causing false memories. Children are especially susceptible to forced confabulation as they are highly impressionable.
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.
Animation of the frontal lobe, shown in red. Fronto-cerebellar dissociation is the disconnection and independent function of frontal and cerebellar regions of the brain.It is characterized by inhibited communication between the two regions, and is notably observed in cases of ADHD, schizophrenia, alcohol use disorder, and heroin use.
Memory goals can either be deliberate (top-down) or in response to an external memory cue (bottom-up). The superior parietal lobe sustains top-down goals, those provided by explicit directions. The inferior parietal lobe can cause the superior parietal lobe to redirect attention to bottom-up driven memory in the presence of an environmental cue.
