Danger changes the way the brain processes innocuous information: a study of sensory preconditioning in rats
|
|
|
|
Abstract:
This thesis used a sensory preconditioning protocol to examine how danger influences the processing of innocuous information. Rats are exposed to pairings of two innocuous stimuli (a sound and light), S2 and S1, and then to pairings of one of these stimuli, the S1, with foot-shock. As a consequence of the pairings in both stages, test presentations of the S2 alone elicit defensive reactions indicative of fear in people, including freezing. Previous work showed that the presence of danger at the time of S2-S1 pairings determines how the association between these stimuli is encoded and consolidated in two regions of the medial temporal lobe: the perirhinal cortex (PRh) and basolateral amygdala complex (BLA). Here a pharmacological approach was used to examine whether danger that occurs after the session of S2-S1 pairings also changes the way that the S2-S1 association is encoded and stored in the PRh and BLA. I show that, in a safe context, the initial (and novel) S2-S1 pairings are encoded in the BLA and that the later (and familiar) S2-S1 pairings are encoded in the PRh. The presence or absence of danger immediately after the session of repeated S2-S1 pairings then determines which of the BLA- or PRh-dependent representations is consolidated in long-term memory and serves as the basis for future learning involving the S2 and S1. When danger is absent, the S2-S1 association is consolidated via protein synthesis-dependent changes in the PRh and not the BLA; and its pre-extinction (through presentations of S2 alone prior to S1-shock pairings) requires activation of N-Methyl-D-Aspartate receptors (NMDAr) in the PRh and not the BLA. In contrast, when rats are shocked in the context shortly after sensory preconditioning, the S2-S1 association is consolidated via protein synthesis-dependent changes in the BLA and not the PRh; and its pre-extinction requires activation of NMDAr in the BLA and not the PRh. Thus, the PRh and BLA play dissociable roles in the processing of innocuous information, and these roles are determined by the level of familiarity of the stimuli as well as the presence or absence of danger around the time of associative formation.
