1) The effects of amygdaloid stimulation upon the blood pressure were observed in forty-four unanesthetized, curarized cats.
2) Simultaneous recording of the blood pressure and electrical activity of the brain were carried out and revealed the existence of close parallelism between the hippocampal electrical activity and blood pressure.
3) Stimulation of the amygdaloid nucleus, septal region and preoptic region generally caused a fall in blood pressure concomitant with appearance of fast waves in hippocampal record, while stimulation of the posterior hypothalamus produced a rise in blood pressure concomitant with appearance of hippocampal regular slow waves.
4) It is suggested that, as far as blood pressure is concerned, the electrical activity of the hippocampus appears to be an indicator of the autonomic activity.
