摘要
1. The effects of temperature acclimation on electrical properties of earthworm axons (Lumbricus terrestris) were studied using intracellular stimulating and recording techniques. 2. Cold acclimation, compared to warm acclimation, was associated with decreased action potential duration and cable input resistance and increased maximum rate of rise and decline of the action potential and increased excitation threshold. In each case the direction of change occurring during acclimation to 5° C was opposite to that occurring immediately after cooling to 5° C, i.e., the acclimation changes were compensatory. 3. The significance of these changes is discussed with regard to their influence on over-all nerve function after thermal acclimation. © 1969 Springer-Verlag.
