Sleeping pills offer wake-up call to vegetative patients

http://www.nature.com/news/2006/060522/full/060522-9.html

It is an amazing story - the sleeping pill zolpidem (its market name is Ambien) can overcome brain shutdown. It becomes "the first treatment for 'persistent vegetative state'". The story sounds unbelievable - a drug for making sleepless people fall in sleep will wake up persons who'll sleep "forever". However, it sounds like the philosphy of Chinese traditional medicine. :) I like this idea.
