BLA modulations of MPP plasticity depend on relative activation timings of the BLA and MPP. (A) Stimulation protocols. Twelve-pulse MPP LFBS started –15, 0, or 15 msec after the onset of 64-pulse LFBS of BLA or LPP. (B) LFBS was delivered to MPP 15 msec before (Δt = –15 ms), concurrently with (Δt = 0 ms), or 15 msec after BLA LFBS (Δt = 15 ms). (C) Summary data for relative timing of LFBS of the BLA and LPP. *, P < 0.05 vs. MPP alone; Student's t test. Data are means ± SEM of four to six rats.
