Epigenetics is involved in strengthening memory

From ScienceDaily: Two broad findings have been seen in memory reconsolidation, which is the retrieval and strengthening of a recent memory. The first broad finding is that, during memory reconsolidation, changes in translational control — the process of forming new proteins from activated genes — occur in areas of the brain related to memory formation. The second broad finding is that epigenetic mechanisms — various molecular modifications known to alter the activity of genes without changing their DNA sequence — are also somehow actively involved during memory reconsolidation or strengthening. Now, researchers at the University of Alabama at Birmingham have described a novel mechanism that links epigenetic change to translational control. In the Journal of Neuroscience, they report how several Read More ›
