In the slowly adapting stretch receptor neurons the temporal decline of the impulse frequency in response to intracellular current stimulation can be interpreted--apart from the high initial overshoot--by the sum of two exponential functions with time constants of approximately 1 and 10 s. In the rapidly adapting cells the discharge frequency decays--after only a little initial overshoot by current step stimulation--nearly rectilinear with about 8 imp./s2 and stops suddenly mostly in the range of 5 s. The current-frequency-characteristic curves show for both receptor cell types nearly straight lines to 7 nA.
在慢适应性牵张感受器神经元中,除了高初始超调外,对细胞内电流刺激的冲动频率随时间的下降可由两个时间常数分别约为1秒和10秒的指数函数之和来解释。在快适应性细胞中,电流阶跃刺激后仅出现一点初始超调,放电频率以约8次/秒²的速率近似直线下降,并大多在5秒范围内突然停止。两种感受器细胞类型的电流-频率特性曲线在7纳安以内均显示出近乎直线。
