hemisphere

 [hem´ĭ-sfēr]
half of a spherical or roughly spherical structure or organ.
cerebral hemisphere one of the paired structures constituting the largest part of the brain, which together comprise the extensive cerebral cortex, centrum semiovale, basal ganglia, and rhinencephalon, and contain the lateral ventricle. See also brain.
cerebellar hemisphere either of the paired portions of the cerebellum lateral to the vermis.
dominant hemisphere the cerebral hemisphere that is more concerned than the other in the integration of sensations and the control of many functions. See also laterality.

[TA]
the large mass of the telencephalon, on either side of the midline, consisting of the cerebral cortex and its associated fiber systems, together with the deeper-lying subcortical telencephalic nuclei (that is, basal nuclei [ganglia]).

cerebral hemisphere

one of a pair of large lobes in the forebrain of vertebrates. In reptiles, birds and mammals the coordinating function is dominant and the cerebral hemispheres control most of the activities of the animals, whereas in lower vertebrates the hemispheres are associated mainly with the sense of smell. In mammals the enlargements of the cerebral hemispheres, the largest part of the BRAIN, are caused by the development of the NEOPALLIUM (part of the CEREBRAL CORTEX) which forms the entire roof and sides of the forebrain. The frontal lobes are particularly developed in humans and are the seat of memory, thought and a considerable part of what is considered to be intelligence.
