Fig. 1. Frequency of occurrence of 0.1°C intervals of (A) brain and jugular temperatures and (B) carotid temperature. The brain distribution is narrower and its mode temperature occurs to the right of the carotid and jugular distributions. The frequency of occurrence of jugular temperatures is to the left of the carotid distribution and is characterized by a long tail. Values are means ± s.d. (see text for N).
