Abstract
Memory is a reference formed from a past experience that is used to respond to present situations. However, the world is dynamic and situations change, so it is important to update the memory with new information each time it is reactivated in order to adjust the response in the future. Recent researches indicate that memory may undergo a dynamic process that could work as an updating mechanism. This process which is called reconsolidation involves destabilization of the memory after it is reactivated, followed by restabilization. Recently, it has been demonstrated that the initial destabilization process of reconsolidation requires protein degradation. Using protein degradation inhibition as a method to block reconsolidation, recent researches suggest that reconsolidation, especially the protein degradation-dependent destabilization process is necessary for memory reorganization.
Highlights
Memory can be stored for either a relatively short or a long period of time
We will focus on recent studies exploring the mechanism of destabilization induced by reactivation of a previously consolidated memory and show how these findings can be used to demonstrate that reconsolidation can work as an updating mechanism
Recent studies focusing on the destabilization process of reconsolidation has provided understanding of the mechanism of reconsolidation, and gave a breakthrough to demonstrate the requirement of reconsolidation for memory updating
