Extract

Cerebral electrostimulation of subconvulsive intensity causes an increase in the concentration of adrenaline-like substances in the blood (Weil-Malherbe and Bone, 1952b). This increase becomes more pronounced as the pulse repetition rate is raised from 200 pulses per second (p.p.s.) to 500 p.p.s., in contrast to the motor, sensory, and respiratory effects which diminish under these conditions (Montagu, 1955). The increasing response to the higher repetition rates showed no sign of reaching a peak in these experiments, except in one case, and since it was not possible with the existing apparatus to exceed 500 p.p.s., the optimal conditions for eliciting the response remained undetermined. With the aid of a more versatile stimulator the adrenaline-frequency relationship has subsequently been studied more extensively, and the results are presented in this article.∗
