AP waveform constancy during repetitive firing: Comparison of corticospinal and corticostriatal neurons. (A) Example trains of APs at approximately 10 Hz in corticospinal and corticostriatal neurons. (B) Individual corticostriatal AP waveforms from a 10-Hz train. Black: first AP; gray: Subsequent APs. (C) Width of successive APs in a 10-Hz train averaged for corticospinal (black, n = 23) and corticostriatal (gray, n= 10) neurons (mean ± SEM). (D) Percent difference from first to eighth AP for the change in AP width. (E) Percent difference from first to eighth AP for the change in falling slope (minimum dV/dt).
