Electrocorticogram, cerebral blood flow, and biochemical and pharmacological findings in the case of the administration of GABOB were obtained respectively by the use of the perfusion method, and then the correlation of each appearance waseinvestigated. 1). Electrocorticogram of perfused cat brain was supressed by administration of GABOB in all cases. 2). The rate of cerebral blood flow, oxygen and glucose consumption and the liberation of lactic acid were all increased by the same treatment. 3). The above mentioned changes were reversible, namely those turned to normal soon after the interruption of GABOB administration. 4).
