Cerebral hemisphere
The vertebrate cerebrum (brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral cortex, that is supported by an inner layer of white matter. In eutherian (placental) mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers. Smaller commissures, including the anterior commissure, the posterior commissure and the fornix, also join the hemispheres and these are also present in other vertebrates. These commissures transfer information between the two hemispheres to coordinate localized functions. There are three known poles of the cerebral hemispheres: the occipital pole, the frontal pole, and the temporal pole. The central sulcus is a prominent fissure which separates the parietal lobe from the frontal lobe and the primary motor cortex from the primary somatosensory cortex. Macroscopically the hemispheres are roughly mirror images of each other, with only subtle differences, such as the Yakovlevian torque seen in the human brain, which is a slight warping of the right side, bringing it just forward of the left side. On a microscopic level, the cytoarchitecture of the cerebral cortex, shows the functions of cells, quantities of neurotransmitter levels and receptor subtypes to be markedly asymmetrical between the hemispheres. However, while some of these hemispheric distribution differences are consistent across human beings, or even across some species, many observable distribution differences vary from individual to individual within a given species.

cerebral hemisphere
A cerebral hemisphere refers to one of the two halves or regions of the brain, divided by a deep longitudinal fissure. Each hemisphere, the left and the right, controls the opposite side of the body and has different specialized functions in most people. For instance, the left hemisphere is typically responsible for language, logic, and analytical thinking, while the right hemisphere is associated with creativity, spatial ability, artistic, and musical skills.

Cerebral hemisphere
A cerebral hemisphere is one of the two regions of the vertebrate brain that are delineated by the median plane,. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter called the cerebral cortex that is supported by an inner layer of white matter. In eutherian, i.e., placental, mammals, the hemispheres are linked by the corpus callosum, a very large bundle of nerve fibers. Smaller commissures also join the hemispheres, both in eutherian and in other vertebrates, including the anterior commissure, posterior commissure, and hippocampal commissure. These commissures transfer information between the two hemispheres to coordinate localized functions. Macroscopically the hemispheres are roughly mirror images of each other, with only subtle differences. On a microscopic level, the architecture, types of cells, types of neurotransmitters and receptor subtypes are markedly asymmetrical between the two hemispheres. However, while some of these hemispheric distribution differences are consistent across human beings, or even across some species, many observable distribution differences vary from individual to individual within a given species.
