Abstract

It was possible to follow the changes in the electroencephalogram during a protracted period in a group of 29 dogs in whom the middle cerebral artery had been clipped to its origin. A slight variation in the location of the clip was unavoidable but useful in that the size of the resulting infarcts differed. Massive lesions included the cortex in the fronto-temporo-parietal region, the striatum, the internal capsule and the anterior portions of the thalamus and, rarely, the hypothalamus. The majority of lesions were confined to the internal capsule and to the caudate nucleus. The clinical syndrome consisted of a contralateral spastic hemiparesis with the loss of the placing reaction and of position sense. Forced circling movements occurred towards the side fo the lesion, persisting even after blindfolding the animal. The changes in the electroencephalogram varied with the size of the lesion. In the scalp to ear records, slow frequencies were most conspicuous over the involved hemisphere in all types of recordings and were most prominent in recording to the contralateral ear. In the scalp to scalp records, flattening was evident over the frontal and temporal regions and slow frequencies were conspicuous posteriorly. Flattening wa...Continue Reading

Basal Ganglia

Basal Ganglia are a group of subcortical nuclei in the brain associated with control of voluntary motor movements, procedural and habit learning, emotion, and cognition. Here is the latest research.
