Aronsohn. The great difference in these basal thermo-taxic centres, with regard to their accompanying temper-ature curves as to rapid and slow rise of temperature, theirshort and long duration make it self-evident that we aredealing with different centres. It has been thought that the fibres coming from the cor-tical thermotaxic centres might be injured and concerned inthis rise of temperatuae about the basal thermotaxic cen- Tixp. Fig. 6. tres ; but the manner of the rise and the duration of thetemperature excludes this view. For instance, the temper-ature curve after injury of caudate nucleus, and after lesionof the cruciate cortex centre above it, are totally for the same reason can the temperature variations,by insults to centres behind or beneath it, be ascribed tothe caudate nucleus. It makes a great difference whetheryou select the point where a lesion with probe is accom-panied by the highest temperature,or to a point in the neigh- THE THERMO-POL YPNQLIC CENTRE.

All opinion is that the sensory fibres stand in a veryclose relation with these thermotaxic centres, in order toregulate the relation between H. P. and H. D.
