The peak amplitude of the IPSPs in the LP neuron appeared sensitive to the slope of the rising phase of the presynaptic depolarizations. A. The IPSPs in response to the 5th waveform (see Fig. 5A) elicited with DC 46% (left panel) and 17% (right panel) corresponding to cycle period 500 ms. The amplitude of IPSPAB is smaller than that of IPSPPD for DC 46% only. B. The steady-state amplitudes of IPSPPD and IPSPAB were normalized to the steady-state amplitudes of IPSPAB/PD at frequency 0.67 Hz for DC 46%. The values were plotted as a function of presynaptic frequency. The relative contribution of IPSPPD was significantly larger for the lowest frequencies (N = 6). C. The amplitudes of the IPSPs in response to DC 17% were normalized as in B and plotted vs. frequency (N = 6). Results obtained were similar to those in B. (* indicates significant difference).
