We studied the effect of temperature on median motor responses in a 41‐year‐old man with organophosphate intoxication. At 32°C, a normal amplitude compound motor action potential (CMAP) and a smaller spontaneous repetitive discharge (SRMAP) were present. With warming to 39°C, the CMAP amplitude decreased 20%, while the SRMAP amplitude decreased 33%. With cooling to 14°C, the CMAP amplitude decreased 9%, while the SRMAP became unobtainable. Possible mechanisms for these findings are discussed. © 1998 John Wiley & Sons, Inc. Muscle Nerve 21:958–960, 1998.
