Scientists uncover a potential mechanism behind sleep-induced memory changes.
The morphing structure of the brain’s “cartilage cells” may regulate how memories change while you snooze, according to new research in eNeuro.
Sleep lets the body rest, but not the brain. During sleep, the brain accounts for a day of learning by making strong memories stronger and weak memories weaker, a process known as memory consolidation. But changing memories requires changing synapses, the connections between neurons. Sleep-induced changes need to overcome perineuronal nets, cartilage-like sheaths that not only surround and protect neurons, but also prevent changes in synapses.
