(A) Mean(± S.E.M.) extracellular 5-HT in the BLA before, during and after a 5 m juvenile social exploration (SE). Rats received prior escapable tailshock (ES, n = 7), inescapable tailshock (IS, n = 7), or home cage control (HC, n = 6) treatment. 5-HT is expressed as a percentage of the average of 4 baseline samples (B1–B4). A juvenile conspecific was added to the dialysis bowl 8 m after B4 was collected, remained in the cage for 5 m and was removed 2 m before the SE sample was collected (depicted as a solid black box). Prior IS significantly increased BLA 5-HT during (SE) and after (P1) compared to ES and HC groups, *ps < 0.05. (B) Graphic reconstruction of 2mm dialysis probe placements within the BLA. Illustrations were adapted from the atlas of Paxinos and Watson (51) and are listed in relationship to bregma in mm.
