MIT reports key pathway in synaptic plasticity

... Several key molecules are involved in normal synaptic formation, but their interactions are not well understood. Now MIT neuroscientists have taken an important step toward solving this challenging jigsaw puzzle. They have pieced together a direct linear pathway connecting three m...

Myelin suppresses plasticity in the mature brain

New Haven, Conn.-Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain.......
