Struggling to remember something you wanted to do today? Then take a nap,it may help improve your memory,a new study has claimed.

Researchers at the Washington University in St Louis found that sleeping well helps people remember tasks on their to-do lists.

The scientists said feeling refreshed after a full night’s rest is a great aid to “prospective memory” – which helps a person to remember to do something in the future.

The findings can help understand better the role sleep plays in brain processing as well as memory,they said.

“We found that sleep benefits prospective memory by strengthening the weak associations in the brain,and that hasn’t been shown before,” study author Prof Mark McDaniel was quoted as saying by the Telegraph.

For their study,the scientists tested 24 university students,asking them to perform different word games on a computer.

Some students were prepared for the test one evening and did it the following morning,while others did the test during the evening,after being prepared earlier that day.

The students who slept in between preparing and taking the test performed very strongly in the prospective memory test.

The researchers believe that the prospective memory process happens during “slow wave” sleep — an early pattern in the sleep cycle — involving communication between two areas of the brain,the hippocampus and the cortical regions.

According to them,the hippocampus is very important in memory formation and reactivation,and the cortical regions are keys to storing memories.

Michael Scullin,co-author of the study,said: “We think that during slow wave sleep the hippocampus is reactivating these recently learned memories,taking them up and placing them in long-term storage regions in the brain.

“The physiology of slow wave sleep seems very conducive

to this kind of memory strengthening.”
