Figure 7. The s.o. interneurone can be coupled by chemical synapses without concomitant electrotonic coupling.

Figure 7

A, the tonic firing of one cell causes repetitive IPSPs in the other cell, whereas a tonic hyperpolarization has no effect on the other cell. B, paired pulse depression is evoked by two action potentials separated by 240 ms, triggered at 0.5 Hz. Data are averaged from 32 sweeps. C, the reversal potential of the synaptic potential is near −70 mV (averaged from 32 sweeps). D, amplitude distribution of the IPSPs (n = 76), showing a relatively stable amplitude.
