The cerebrum is divided by the medial longitudinal fissure into two cerebral hemispheres, the right and the left. The cerebrum is contralaterally organized, i.e., the right hemisphere controls and processes signals (predominantly) from the left side of the body, while the left hemisphere controls and processes signals (predominantly) from the ...

The supratentorial region contains the cerebrum, while the infratentorial region contains the cerebellum. Although the Roman era anatomist Galen commented upon it, the functional significance of this neuroanatomical division was first described using ‘modern’ terminology by John Hughlings Jackson , founding editor of the medical journal Brain .
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
The frontal lobe is located at the front of each cerebral hemisphere and positioned in front of the parietal lobe and above and in front of the temporal lobe.It is separated from the parietal lobe by a space between tissues called the central sulcus, and from the temporal lobe by a deep fold called the lateral sulcus, also called the Sylvian fissure.
The cerebrum is the most anterior part of the brain, located in the top half of the skull, consisting of two hemispheres separated by a fissure and connected by the corpus callosum. It is responsible for integrating complex sensory and neural functions, and subsequently initiating and coordinating voluntary activity in the body.
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.
Transformations of the visual field toward the visual map on the primary visual cortex. U=up; D=down; L=left; R=right; F=fovea. The visual map theory was published by the famous neuroscientist and pioneer Santiago Ramón y Cajal (1898). According to this theory, the function of the optic chiasm is to repair the retinal field image on the visual ...
