Examples of depolarizing current elicited IPSPs in VP1 for conditioned animals and pseudorandom controls. (A1)An example from a conditioned animal of spikes evoked bya2sec0.3 nA depolarizing current pulse applied to an identified type Ie interneuron. (A2) An increase in the number of IPSPs relative to baseline recorded in VP1 elicited by depolarization of Ie.(B1)An example from a pseudorandom control animal of spikes evoked by a 2 sec 0.3 nA depolarizing current pulse applied to an identified type Ie interneuron. (B2) IPSPs in VP1 evoked by depolarization of Ie from a pseudorandom control. (C) Group data depicting the mean percent increase from baseline in VP1 IPSPs elicited by depolarization of identified type Ie interneurons from conditioned animals (n = 12) and pseudorandom controls (n = 9; *P < .05).
