Figure 3. Incremental responses.

Figure 3

Two representative incremental responses are shown superimposed and in isolation. For MUNE calculation amplitudes of each increment are measured peak-to-peak. Increment #1 is the initial all-or-none response recorded and represents a single motor unit potential (SMUP). Each subsequent increment (#2–10) represents a quantal increase superimposed on the prior response. Therefore to obtain the SMUP amplitudes for increments 2–10, the amplitude of the prior response is subtracted from the amplitude of the increment obtained.
