Effects of Pentobarbital and Ether upon Vasomotor Responses from Cerebral Cortex of the Dog. ∗

Summary

1. Electrical stimulation of the anterior cerebral cortex of the dog under pentobarbital anesthesia gives predominantly depressor responses. 2. Under ether anesthesia the response is usually pressor. Some stimuli are followed by a rise of blood pressure of one of 2 minutes duration, while others are accompanied by only 15 to 20 seconds of pressure elevation. 3. The mode of action of these anesthetics in affecting the cortically induced blood pressure response is not understood.
