Abstract
Electrical stimulation of certain points within the hypothalamus of shivering cats under pentobarbital anesthesia causes a suddon termination of shivering. The anatomical region within the brain stem from which this suppressor effect can be evoked was mapped by the use of the Horsley-Clarke stereotaxic apparatus, and the region extends throughout the hypothalamus and midbrain, the preoptic region being most effective. It is proposed that the suppressor effect is a mechanism for suppression of shivering when the musculature is needed for skeletal movement.
