Abstract
The effect of stimulation of the mammillary bodies (MM) on the reflex activity and autonomic nervous activity was investigated and the followings observed.
1) The amplitude of the photo-evoked eyelid mic rovibration (MV) increased by stimulation of the MM with 3 Hz but decreased with 100 Hz.
2) The amplitude of the sciatic-evoked ey elid microvibration (SMV) decreased by stimulation of the MM with both 3 and 100 Hz.
3) The amplitude of the nociceptiv e reflex decreased by stimulation of the MM with 100Hz.
4) The amplitude of both the M and H waves decreased by stimulation of the MM with both 3 and 100 Hz.
5) Intestinal movement was facilitated by stimulation of the MM with both 3 and 100 Hz.
6) Stimulation of the MM with both 3 and 100 Hz had almost no effect on the blood flow volume in the common carotid artery and the femoral artery.
