2017-01-29 Research from the Sylvain Williams laboratory was chosen as one of the top ten discoveries of 2016 by Quebec Science magazine. The group was able to show that REM sleep plays an important role in memory consolidation. They used an advanced optogenetics approach to block theta oscillation in the hippocampus specifically in this sleep phase, and showed this impaired memory. This important discovery, published in the journal Science, puts to rest 15 years of controversy about the role of REM sleep in memory.
