Description

The finding of memory reconsolidation in invertebrates has provided important insight into evolutionary conservation and the adaptive value of the mechanisms involved in memory reprocessing. Furthermore, due to the characteristics of some memory models, important aspects of reconsolidation were initially found in invertebrates and were then confirmed in vertebrates. In the present chapter, we revisit the findings obtained using the context-signal memory model in crabs. These studies were performed both at the behavioral level, to describe the parametrical conditions for memory labilization and reconsolidation, and at the mechanistic level, to describe the molecular features involved in memory reconsolidation and extinction. We then review comparative studies in rodents in which the role of the molecular mechanisms described in invertebrates was evaluated in the contextual memory paradigm of fear conditioning. Comparative studies in humans on the nature of the reminder for reconsolidation are described in another chapter of this book.
