Sleep is critical for hippocampus-dependent memory consolidation. However, the underlying mechanisms of synaptic plasticity are poorly understood. The central controversy is on whether long-term potentiation (LTP) takes a role during sleep and which would be its specific effect on memory. To address this question, we used immunohistochemistry to measure(More)
IMPACT is an inhibitor of GCN2, a kinase that phosphorylates the alpha subunit of the translation initiation factor 2 (eIF2 alpha). GCN2 has been implicated in regulating feeding behavior and learning and memory in mice. IMPACT is highly abundant in the brain, suggesting its relevance in the control of GCN2 activation in the central nervous system. We(More)
