Effects of intra-BLA of DHPG on the number of recoveries during the VCT. (A) DHPG at 0.1 μM but not 1.0 μM increased the number of recoveries in OVX but not OVX + EB rats. Estradiol by itself decreased the number of recoveries when compared OVX + EB-vehicle and OVX-vehicle. (B) DHPG (0.1 and 1.0 μM) did not alter the number of recoveries the number of recoveries in male rats. Male rats displayed significantly more recoveries when compared to OVX + EB Values represent mean ± SEM. * = p ≤ 0.05; ζ = sex differences when compared male-vehicle with OVX + EB-vehicle and OVX-vehicle. OVX + EB: vehicle, n = 19; DHPG (0.1 μM), n = 9; DHPG (1.0 μM), n = 12; OVX: vehicle, n = 20; DHPG (0.1 μM), n = 10; DHPG (1.0 μM), n = 17; male: vehicle, n = 12; DHPG (0.1 μM), n = 8; DHPG (1.0 μM), n = 6.
