Panel A – Excitotoxic lesions of the BNST block CRF-enhanced startle but not fear-potentiated startle to a 3.7-sec shock-paired CS, whereas excitotoxic lesions of the CeA block fear-potentiated startle to the 3.7-sec CS, but do not affect CRF-enhanced startle (data from Lee and Davis, 1997). Panel B – Infusions of the AMPA receptor antagonist NBQX into the BNST block light-enhanced startle but not fear-potentiated startle to a 3.7-sec CS, whereas NBQX infusions into the CeA block fear-potentiated but not light-enhanced startle (data from Walker and Davis, 1997b). Potentiation scores are expressed as differences from control (i.e., either sham-lesioned or vehicle-infused).
