The effect of intra-amygdala infusions of the CCKB antagonist PD-135158 on potentiation of startle induced by i.c.v. pentagastrin infusions. Startle responses (±SEM) are shown across time. All rats received i.c.v. infusions of pentagastrin (100 nm) and bilateral intra-amygdala infusions of PD-135158 (10 μg) or its vehicle. Startle responses after i.c.v. pentagastrin infusions were reduced by intra-amygdala infusions of PD-135158, although this attenuation was not statistically significant (p = 0.054).
