Brain able to work at sleep

DO you learn anything when you are sleeping? Scientists believe that it is possible to learn simple responses while you are asleep.

What you cannot retain, however, is factual information.

To actually learn something during sleep, you would have to be able to transfer the new knowledge into your long-term memory.

This does not happen while you are sleeping. This inability is often seen in patients who have Alzheimer's disease.

People can process information, however, and they can remember during their sleep events that happened while they were awake. Or they can process information gained even earlier.
