Pharmacological profiles of excitatory and inhibitory synapses of B64. A, The glutamate antagonist, 10−4 m CNQX, abolishes B64-elicited EPSPs in B3 (A1, summary data in A3) but has no effect on B64-elicited IPSPs in B61/62 (A2, summary data in A4). B, QA at 10−5 m occluded the IPSPs from B64 to B61/62 (B1, summary data in B2). B64 was stimulated at 20 Hz for 2 s. All recordings were made in high-divalent saline. Bonferroni post hoc tests: *p < 0.05; **p < 0.01; ***p < 0.001. Error bars indicate SEM. Numbers at the beginning of traces are membrane potentials (in millivolts).
