Subthreshold fast EPSPs evoked spikes dur-ing the rising phase of a slow EPSP, but suprathreshold fast EPSPs could not evoke spikes later in a slow EPSP.

WebbWhen evoked at membrane potentials between ‐20 and ‐55 mV after blockade of outward K+ currents and fast Na+ spikes by intracellular injection of Cs+ and QX‐314 (n = 5 neurons), a slow depolarizing potential emerged near the fast peak of the EPSP. This slow potential, unlike the fast peak, was not linearly related to membrane potential. 3. WebbSlow EPSP lOnA 40 mV-48 mV • 01 s Fig. 2. Excitability changes during the slow EPSP. The lefthand trace shows the control response to a long current pulse, the middle trace the response to the same current at the peak of the slow EPSP (note the small depolarization) and the righthand trace the response 2 min after the beginning of the slow EPSP.
