Figure 4. Effect on temperature regulation of lesions in the 
brain of a rabbit. The part of the brain destroyed by the puncture 
is indicated by the stippled area. The lesions in the two left-hand 
sections left temperature regulation undisturbed as determined by 
a cold exposure test. The lesion represented in the upper right- 
hand figure abolished temperature regulation, making the animal 
poikilothermic. Data of Isenschmid and Kiehl (1912),
