Autonomic effects on stimulating rostral portion of cingulate gyri in man
Pool JL and Ransohoff J (1949) Autonomic effects on stimulating rostral portion of cingulate gyri in man. J Neurophysiol 12:6 385–92.
First Paragraph: In a review of the anatomy and function of the anterior portion of the cingulate gyrus, Ward reviewing the work of Smith and others states that electrical stimulation of the rostral cingular cortex in the monkey may yield autonomic responses, motor effects and a suppressor action. Regarding the autonomic responses he says that “marked respiratory slowing and arrest up to 25 seconds may be obtained from the more rostral and deeper portions of this region, being most marked anteriorly. Marked cardiovascular effects are also obtained, consisting of vagal slowing of the heart, cardiac arrest and a marked fall as well as the occasional rise in blood pressure.
Context
- Series of 13 cases in man with stimulation of the posterior cingulate during psychosurgery. Most patients showed an elevation of blood pressure, persisting up to 5 minutes after stimulation was stopped. Heart rate fell in 7 cases, lasting up to 10 minutes after stimulation, and rose in 3. Respiratory rate rose in two cases and fell in two cases. The authors felt that respiratory changes were more caudal, cardiovascualar representation more rostral.
