Question

Would you prefer amplitude of the pulse to be small or large? Why?​

Answer 1

Answer:

Explanation:

For the pulse amplitude (A) sufficiently low, one obtains only a subthreshold response to each stimulus of the pulse train. This 1:0 response can be seen at any value of ts, the time between stimuli. For A sufficiently high at a given ts, the stimulus is suprathreshold, and so one can obtain action potentials. In that case, for ts sufficiently large, one sees a 1:1 rhythm, in which each stimulus produces an action potential (Fig. 1A). (An N:M rhythm is a periodic pattern consisting of repeating N:M cycles each containing N stimuli and M action potentials. The period of repetition of the waveform is thus Nts. The M action potentials will in general have M different morphologies.)
