In a companion study (Carnicella et al., 2005), we showed that the muscarinic antagonist atropine, when administered after extensive training during both conditioning and testing, affected neither cued nor contextual fear memories when both of them did not compete for the control of the overt behaviour. In contrast, atropine altered the degraded contingency effect (DCE), that is, the processes by which contextual fear memory competes with the cued one for the control of the conditioned response… CONTINUE READING
