The
results, Professor Stickgold said, suggest that a good night’s sleep
immediately after

learning is
“absolutely required” to embed new skills in the memory. “We think that the

memories

normally
wash out of the brain unless some process nails them down.

My
suspicion is that sleep

is one of
those things that nails them down.”
