In humans, the cerebrum is the largest and best-developed of the five major divisions of the brain. The cerebrum is made up of the two cerebral hemispheres and their cerebral cortices (the outer layers of grey matter), and the underlying regions of white matter. [2] Its subcortical structures include the hippocampus, basal ganglia and olfactory ...

Brodmann published his maps of cortical areas in humans, monkeys, and other species in 1909, [2] along with many other findings and observations regarding the general cell types and laminar organization of the mammalian cortex. The same Brodmann area number in different species does not necessarily indicate homologous areas. [3]
The outer part of the cerebrum is the cerebral cortex, made up of grey matter arranged in layers. It is 2 to 4 millimetres (0.079 to 0.157 in) thick, and deeply folded to give a convoluted appearance. [21] Beneath the cortex is the cerebral white matter. The largest part of the cerebral cortex is the neocortex, which has
In the anatomy of animals, the brain, or encephalon, is the supervisory centre of the nervous system. Although the brain is usually cited as the supervisory centre of vertebrate nervous systems, the same term can also be used for the invertebrate central nervous system. In most animals, the brain is located in the head.
Each olfactory lobe connects to the ipsilateral (same-side) centers of the frontal cerebrum. [2]: Figs. 11.3, 11.7 Figs. 11.3, 11.7 In chondrichthyans (e.g., sharks and skates ), the thalamus does not retrieve a branch from the optic tract but only from the contralateral optic tectum , so that the optic path decussates twice, and the forebrain ...
Thalamocortical radiations – fibers between the thalamus and the cerebral cortex, associated with activity which causes symptoms associated with impulse control disorders, Parkinson's disease, attention deficit hyperactivity disorder, and other forms of chronic psychosis
The capsule itself appears as a thin white sheet of white matter. [ 1 ] The external capsule is a route for cholinergic fibers from the basal forebrain to the cerebral cortex .
