CENTRAL AND PERIPHERAL MECHANISMS 
Our second conclusion is that shivering can e produced during 
differential cooling of the head or the trunk alone as well as in the 
course of whole body cooling. Either "peripheral" or "central" 
shivering can be produced repeatedly and also inhibited by elevation 
of skin temperature in "central shivering" or brain temperature 
in "peripheral shivering". From these data, it is inferred that the 
onset of shivering in the anesthetized animals depends upon both 
central and peripheral temperatures; the peripheral temperature 
in shiveringinthiscase is more potent than the central temperature.
