The excitatory and recovery processes in the nerve fibre as modified by temperature changes

摘要: 1. 1. An exponentially rising current excites an isolated single nerve fibre when, and only it rises above crosses the rheobase at a rate of rise greater than minimal gradient fibre. The is not affected by changes in temperature. shows tendency to be increased cold, but there marked hysteresis effect temperature on gradient. 2. 2. A brief subthreshold shock produces excitatory state which first then falls after end shock. time course this process retarded cold. minimum quantity electricity needed excite its coefficient being 1.7 for change 10°C. 3. 3. At every temperature, earliest return excitability occurs immediately spike. recovery same extent as spike duration.
