Effects of bilateral microinjection of 200 nL of vehicle, 4 nmol of LY235959 (LY), or 0

04 nmol of N-propyl in the percentage of time spent in freezing behavior of fear-conditioned rats ( = 5/group) 10 min before the 1st reexposition of context (day 1) and 6 days before the 2nd reexposition to context (day 7).

Time course of the effects of bilateral microinjection of 200 nL of vehicle, 4 nmol of LY235959 (LY), 4 nmol of NBQX, 0

04 nmol of N-propyl, or 1 nmol of c-PTIO in the mean arterial pressure (ΔMAP) and heart rate (ΔHR) recorded in nonconditioned and fear-conditioned rats ( = 5/group). Asterisk indicates significant treatment effect ( < 0.05) compared with vehicle- and NBQX-treated animals.
