Temperature effects on a slow-crustacean neuromuscular system.
The membrane potential of the E2 axon and the bender muscle fibers increased with temperature. The input resistance of the axon, the spike amplitude and time course declined with temperature. Excitatory junctional potentials (ejps) exhibited maximum amplitudes and minimum facilitation at about the same temperature. Ejp time course and muscle membrane input resistance declined with temperature. Tension produced by the muscle also declined but then increased when additional spikes were generated in the periphery of the E2 axon.
