Temporal dispersion motor conduction

With increasing lengths of nerve segment between stimulating and recording electrodes, temporal dispersion increases and amplitude decreases.
A: Stimulus onset.
B: CMAP onset.
C: Peak amplitude of negative phase.
D: Return to baseline.
E: Peak of positive phase.
F: Return to baseline.
A-B: Latency.
B-C: Rise time.
B-C-D: Area under the curve.
B-D: Duration of negative phase.
C-E: Peak-to-peak amplitude.
