In the group’s working hypothesis, an adaptive function of reconsolidation and consolidation is to enable the induction of changes in memory expression by endogenous processes activated by concurrent experiences. A central goal is to show that the integration of internal states (e.g. emotions) to the memory trace is part of the process(es) that determines the expression of reactivated memories. Here, in the Neohelice aversive memory paradigm, we evaluate the possibility of combining the analysis of changes in behavior triggered both by reactivation of the mnesic trace and by variations of internal states in the same animal. We propose, via individual video analysis, the dissection of the escape response triggered by the visual danger stimulus from other behaviors in the training-testing arena (e.g. active freezing response, place preference) during both the exposure to the training-context and the visual danger stimulus. Parameters such as the shift of the area occupied by the crab, the trajectory distance or the immobility periods, seem to be suitable for this approach. For instance, all these parameters disclose significant differences during the training session. The initial analysis shows that this data-obtaining system might be a really reliable tool to keep track of the different possible behaviors.
