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.

Seven single voxels, approximately 8 cc in volume, were positioned within the medial frontal gray matter, the left frontal white matter, left parietal white matter, the right temporal lobe at the superior temporal gyrus, the left basal ganglia, left cerebellar hemisphere (gray and white matter), and the cerebellar vermis, respectively (Figure 1).
More precisely, these cerebellar regions are lateral portions of cerebellar hemispheres and the dentate nucleus, which project to the cerebral cortex much more than any other cerebellar region, and thus, the term "neocerebellum" is used (10).

Brain capillary telangiectasias are typically found in the pons, (1,2,4,5) but are also commonly located in the medulla, caudate nucleus, cerebrum, (3) cerebellar hemispheres, and in the spinal cord.

Like the cerebral hemi spheres, the cerebellar hemispheres are formed by paired dorsal swellings that grow individually and are aligned at the midline.
Diffusion-weighted images from MRI 5 days after admission revealed symmetric diffusion hyperintensity within the bilateral cerebellar hemispheres, bilateral caudate heads, and hippocampi (Figure 2).
