Moderate hypochermia, or a slight reduction of body temperature from a point within the normal limits of the range of body temperature variability, has been given some attention in the clinical literature, This attention has been focused primarily on functional somatic changes or variations induced by the hypothermia. Observations dealing with behavioral functions have come mainly from clinical studies in which the behavioral data were secondary to the application of hypothermia in medical or surgical procedures (Fay, 1940; Allen, et al., 1960). In these observations there have been reports of a behavioral deficit in cognitive functioning. Previous experimental studies (Essman, Sudak, & Blumstein, 1961; Essman 8i Sudak, 1962; Sudak & Essman, 1962?) have suggested impaired maze acquisition when body temperature was lowered (2OC co 5OC), a cemperature-dependent variable related to learning, and no effect of such a moderate degree of temperature reduction upon performance. The precise limits of temperature variability in the mouse (Mus masctdlar) have not been clearly defined. In one instance (Speccor, 1956, p. 343) 35.2'C to 37.9'C has been specified. In another instance (Usinger, 1957) the range is given as 34'C to 39°C for ambient temperatures of 20°C to 35°C. In our own experience we have found that in individual measurements made on SwissWebster mice variation of deep colonic temperature occurs from 36'C to 39OC at an ambient temperature of 25°C & l.O°C. The question arising out of previous work has been what degree of reduction from the upper normochermic range must a temperature be to influence the acquisition of a simple maze response. This implies the hypothesis chat temperature reduction per se rather than a temperarure difference within the norrnochermic range is [he critical variable as far as the acquisition process is concerned. Furthermore, it is hypothesized that moderate sustained hypothermia will interfere with acquisirion while moderate temporary hypothermia will have no effect. This hypothesis is based upon the premise that a sustained reduction of body temperature during acquisition experience does not allow for neural consolidacion
