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.
Within the medial temporal lobe, familiarity tends to be associated with the perirhinal region while recollection is associated with the hippocampus. Cortical regions related to conscious recollections (feelings of "time travel" according to Tulving) include the frontal lobes, while unconscious feelings of "knowing" may be located elsewhere.
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 ...
Recognition memory is critically dependent on a hierarchically organized network of brain areas including the visual ventral stream, medial temporal lobe structures, frontal lobe and parietal cortices [48] along with the hippocampus. [49] As mentioned previously, the processes of recollection and familiarity are represented differently in the ...
Gall believed that, rather than the brain operating as a single, whole entity, different mental functions could be attributed to different parts of the brain. He was also the first to suggest language processing happened in the frontal lobes. [7] However, Gall's theories were controversial among many scientists at the time.
The uncinate fasciculus is a bi-directional pathway between the temporal lobe and frontal lobe; it is traditionally considered to be part of the limbic system. [2] It has been proposed that the uncinate fasciculus allows mnemonic representations stored in the temporal lobe to interact with and guide decision making in the frontal lobe. [4]
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] It contributes to the dorsolateral and medial prefrontal cortex.
The frontal lobe is the largest of the four major lobes of the brain in mammals, and is located at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is parted from the parietal lobe by a groove between tissues called the central sulcus and from the temporal lobe by a deeper groove called the lateral ...
