Spontaneous and miniature GABAergic activity of PC neurons. (A) Patch-clamp recording of spontaneous GABAergic events from a PC of a naïve animal performed in voltage-clamp at a holding potential of −65 mV in the presence of kynurenic acid (1 mM). (B and C) Similar recordings from an unpaired animal (B) and from a conditioned subject (C). (D–F) Miniature GABAergic events recorded in the presence of 1 μM TTX from a naïve, unpaired, and conditioned animal, respectively. (G) Activity was blocked in the presence of 20 μM gabazine.
