Comparing the effects of repeated (within 10 min) BLA priming to the effects of combined muscimol and BLA priming. In CA1, repeated BLA priming (BLA_BLA) enhanced the LTP reducing effect of a single BLA priming, such that the effect was noticeable already during post-tetanic potentiation * (p < 0.05). In the DG, repeated BLA priming (BLA_BLA) reduced the LTP-enhancing effect of BLA priming * (p < 0.05), but not to the extent of muscimol post-BLA priming (BLA-MUS). §, BLA_BLA vs. BLA-MUS (p < 0.05). It did not reduce the enhancement during the post-tetanic potentiation period except during the LTP phase. For clarity, we did not include the CONT-VEH groups. However, in CA1, the MUS-BLA group was similar to the CONT-VEH group, and in the DG, the level of potentiation towards the end of the BLA-BLA group (at 60 min) was similar to the potentiation level of the CONT-VEH group.
