Resumen:
Although much is known about long-term memory (LTM) consolidation, what
puts the "long" in LTM is the exclusive feature of persisting over time.
However, until recently the molecular mechanisms underneath memory
persistence had never been properly studied. In rats, the protein
translation inhibitor anisomycin impaired memory persistence when
injected into the dorsal hippocampus 12 h after inhibitory avoidance
(IA) training without affecting memory formation. Here, we also show
learning-induced changes in hippocampal c-Fos, Homer 1a, Akt, CamKIIα,
and ERK2 levels around 18-24 h after IA training. Thus, memory
persistence is associated with a late phase of plasticity-related
protein synthesis in the hippocampus
