The brain had multiple hemorrhagic lesions within both cerebral hemispheres and the cerebellum. And it's clear that this whole notion that the left hemisphere is the language hemisphere and the right hemisphere is a visual hemisphere cannot be applied to a rat, okay? It has been known for many years that people with large lesions of the frontal lobes in both hemispheres have great difficulty inhibiting inappropriate behaviors. Given that the dominant view is that the left hemisphere is the happening place for language and the right hemisphere is superior for music, we immediately hit the conundrum, what about singing with words? One area is the subventricular zone of the lateral ventricles, which are fluid-filled cavities in both brain hemispheres connected to the central canal of the spinal cord. The right hemisphere embodies those artistic and intuitive qualities of holistic and integral design that are are familiar in all great design, art and craft. There certainly are differences between the left and right brain hemispheres. Sensory axons extend from the skin of the big toe to the base of the brain; and motor axons run from the motor cortex of the cerebral hemispheres right down to motor neurons at the bottom of the spinal cord. The two hemispheres of the vertebrate brain have also become specialised. Their appearance could also be the result of tissue compression and developing injury in the contralateral hemisphere due to the expanding edema formation. They do both their thinking and acting with only the left brain hemisphere. The left brain hemisphere posterior speech areas showed much greater activation for forward than backward speech. The brain includes the cerebral hemispheres, the cerebellum, and the brain stem. The vertebrobasilar arteries supply the brain stem, cerebellum, and occipital lobes; the cerebral hemispheres are supplied through the carotid arteries. However, since the Chinese language combines sound and shape, both hemispheres are used in speaking Chinese. Lesions in the cerebral hemispheres and brainstem included perivascular lymphocytes in leptomeninges and parenchyma, with scattered microglial nodules in gray and white matter. Our hemispheres always work together so that we will experience a combination of right and left hemisphere in everything we do. Within the hemisphere, three brain regions work together to control reading. Origin Late Middle English (in the sense ‘half the celestial sphere, the sky’): from Old French emisphere, via Latin from Greek hēmisphairion, from hēmi- ‘half’ + sphaira ‘sphere’.
