Postsynaptic stimulation inhibits presynaptic GABA release. A, Electrical stimulation of postsynaptic SON neurons from slices of juvenile rats (P21–P28) induced an increase in the interval between spontaneous GABAergic events indicative of the inhibition of presynaptic GABA release (example trace,n = 56). A 2 Hz stimulation protocol was used (see Materials and Methods). B, Electrical stimulation induced instantaneous but short-term depression of sIPSC frequency.C, Corresponding cumulative frequency plot showing that, after electrical stimulation, short intervals occurred less frequently.
