Sample text

In the absence of atrophy or reflex loss, monoplegia suggests a unilateral spinal cord or, rarely, a cerebral cortical-subcortical lesion. Hemiplegia with retained or heightened reflexes is the common manifestation of a lesion in the cerebral white matter, internal capsule, cerebral peduncle, basis pontis, or pyramid. Most often it is due to vascular disease, less often to trauma, tumor, or an infective or demyelinative process. If facial muscles are spared, the lesion is in the lower brainstem or high cervical cord.

CSF pressure should be measured with the patient relaxed in a horizontal lateral decubitus position. Normally it ranges from 80 to 180 mmH2O, and if the needle is properly placed, small pulse and respiratory excursions are seen. If the pressure is very high (Ͼ300 mmH2O), one should obtain the smallest needed sample of fluid and then, according to the suspected disease and patient’s condition, administer urea or mannitol and watch the pressure in the manometer until it falls. ; and bacteriologic cultures and virus isolation.

Thalamostriate fibers arise from the centromedian-parafascicular complex of the thalamus. CM, centromedial nucleus; DM, dorsomedial nucleus; GP, globus pallidus; IC, internal capsule; PUT, putamen; RN, red nucleus; SN, substantia nigra; VPL, ventral posterolateral nucleus; VPM, ventral posterior medial nucleus. trol. The ones most clearly exposed by disease are decerebrate rigidity and the antigravity support and righting reflexes. In decerebrate rigidity, in which the vestibular nuclei are separated from upper brainstem influences and thereby disinhibited, all four extremities or the arm and leg on one side (ipsilateral to a unilateral lesion) are extended and the cervical and thoracolumbar portions of the spine are dorsiflexed; tonic neck reflexes can often be elicited (passive turning of the head results in ipsilateral extension of the limbs and flexion of the opposite arm).
