Molecular mechanisms of memory reconsolidation
NC Tronson, JR Taylor - Nature Reviews Neuroscience, 2007 - nature.com
Memory reconsolidation has been argued to be a distinct process that serves to maintain,
strengthen or modify memories. Specifically, the retrieval of a previously consolidated …

that increasing histone acetylation after a learning experience enhances memory …

Anisomycin infused into the hippocampus fails to block “reconsolidation” but impairs extinction: the role of re-exposure duration
AE Power, DJ Berlau, JL McGaugh… - Learning & …, 2006 - learnmem.cshlp.org
Recent studies have reported new evidence consistent with the hypothesis that reactivating
a memory by re-exposure to a training context destabilizes the memory and induces …

Retrieval induces hippocampal-dependent reconsolidation of spatial memory
Nonreinforced retrieval can cause extinction and/or reconsolidation, two processes that
affect subsequent retrieval in opposite ways. Using the Morris water maze task we show that …
