Figure 15 : Section of brain stem and reflex production of P.S.

Sagittal section of brain stem and location of the diflferent sections allowing or suppressing production of P.S. by proprioceptive or nociceptive stimulation. Black area: common lesion suppressing P.S. in intact animals. See text for details.
