title: [Correlation between the thalamus EEG and rCBF in the thalamus infarction in the dogs (author's transl)].
abstract: We have made an investigation of the correlation between the changes in thalamic EEG and rCBF immediately following occlusion 4 arteries at the base of the brain using thalamic infarction model with 38 dogs. Changes in EEG patterns due to vascular occlusion were divided into 4 grades. A tendency was found for decreases in rCBF to be greater the more marked were the EEG changes. Animals showing mild EEG changes in which there was only slight attenuation of voltage had rCBF values roughly 63% those prior to occlusion; animals with moderate EEG changes in which there was voltage attenuation and an increase in slow wave components had rCBF values of 34%; and animals with severe EEG changes in which there was voltage attenuation and complete disappearances of fast wave components showed rCBF values of roughly 29%.
