Definition of some of effects of HA on current injection induced depolarization. Superimposition of the initial segment of Pre and HA traces from Fig. 4 aligned by the current injection point. The relative depolarization is defined with the thin vertical line through the point of the upswing of the first AP. The net voltage difference between the holding potential (Vh, denoted by the thin horizontal line) and intersection between the vertical line and Pre or HA trace are relative depolarization for the respective traces. For this neuron, the relative depolarization is approximately doubled by HA. Threshold for AP is defined by the intersection lines drown along the depolarization slope and the rising slope of the AP. There is a slight, non-significant lowering of the threshold from Pre to HA in this neuron.
