A night without sleep may have the same effect on you as a night on the town.
Researchers say sleep deprivation can disrupt brain cells ability to communicate with each other similar to the way drinking too much alcohol can affect the brain. This comes from a study done at UCLA.
It involved epilepsy patients who were preparing for surgery. Electrodes were attached to their heads to study brain patterns.
Researchers found that as the subjects became more tired, parts of the brain would shut down -- impairing function. Scientists say this shows why people have such a hard time getting started after a night of lost sleep.
