The late pop singer, Michael Jackson, once set the record for the biggest-selling album, "Thriller," but recent revelations suggest he might have set a record for the longest time for a human to go without REM sleep.
Dr. Charles Czeisler, a Harvard Medical School sleep expert, testified this week in the wrongful death civil trial between Michael's mother Katherine Jackson and concert promoter AEG Live.
Czeisler testified that no human has ever gone 60 nights without REM sleep, notes CNN.
Jackson's physician, Dr. Conrad Murray, has previously said he gave the singer propofol infusions for 60 nights.
"It would be like eating some sort of cellulose pellets instead of dinner," Czeisler said. "Your stomach would be full and you would not be hungry, but it would be zero calories and not fulfill any of your nutrition needs."
The lack of REM sleep could have taken Jackson's life, if the propofol injections had not, said Czeisler, who also stated that lab rats die after five weeks of no REM sleep.
He said people lose their balance and appetite and their physical reflexes get 10 times slower, while their emotional responses are 10 times stronger.
Katherine Jackson is blaming AEG for hiring Murray and ignoring her son's poor health, while AEG Live claims it was Jackson who chose, hired and supervised Murray.
