21. Vesicles of the forebrain are usually paired, giving rise to hemispheres like the cerebral hemispheres in mammals. 22. The medial longitudinal fissure separates the human brain into two distinct cerebral hemispheres , connected by the corpus callosum. 23. It consists of descending fibers that arise from cells in the motor area of the ipsilateral cerebral hemisphere . 24. The cerebral hemisphere is long, oval and flat, lacking the inflated appearance present in monotremes, multituberculates and therians. 25. It is generally located superficially ( in the uppermost sections ) in the cerebral hemispheres , and involves the leptomeninges. 26. The results of both cases became a vital verification of the relationship between speech and the left cerebral hemisphere . 27. The cerebrum consists of two cerebral hemispheres , separated from each other by a deep fissure called the longitudinal fissure. 28. It is a neurological disorder of the central nervous system characterized by cysts or cavities within the cerebral hemisphere . 29. An example comes specifically from studies on lateral specialization between the left and right cerebral hemispheres of the brain. 30. All of these are controlled by the frontal lobe which is situated at the front of the cerebral hemisphere .
