RSSNo sleep means no new brain cells

Missing out on sleep may cause the brain to stop producing new cells, a study has suggested.
The work on rats, by a team from Princeton University found a lack of sleep affected the hippocampus, a brain region involved in forming memories.
The research in Proceedings of the National Academy of Science showed a stress hormone causes the effect.
A UK expert said it would be interesting to see if too little rather than no sleep had the same consequence.
