Abstract:
To determine the normal median nerve somatosensory evoked potentials in cat and to evaluate the effect of temperature change, following experiment was done. Median nerve somatosensory evoked potentials(MNSEP) were recorded in 45 mongrel cats at 38.5 degrees C, the normal temperature range in cats, and in 8 cats of them MNSEP was recorded at 37.5 degrees C, 36.5 degrees C and 35.5 degrees C additionally. The results were as follows ; 1) Seven peak waves were always recorded and they were named as I, II, P1, III, N1, P2, N2, and central conduction time(CCT) was thought as I-N1 interpeak latency and it was 5.81+/-0.53msec. 2) The peak latencies of all waves and CCT were increased gradually as temperature decreased. The latencies of the late waves increased more than those of early waves as temperature decreased except N2.
