Persistence of visual response in vestibular nucleus neurons in cerebellectomized cat.

abstract：:Selective lesions of the noradrenergic locus coeruleus (LC) system have recently been shown to aggravate both ischemic and epileptic brain damage. This study explores the possibility that the LC system also influences hypoglycemic brain injury. Bilateral 6-hydroxydopamine lesions of the LC projection to the forebrain ...
