The Citi Never Sleeps: Sleep Deprivation Makes You Stupid

Citigroup might want to rethink its insomniac slogan. Although the "Citi Never Sleeps" slogan is meant to convey a sense of never-ending vigilance, a new study shows that sleep deprivation leads to a loss of attentiveness and interferes with visual processing.
The study, which will be published in the Journal of Neuroscience, shows that losing only one night's sleep has a dramatic effect on the brain, making it prone to short, sudden shutdowns. The study suggests that sleep-deprived people alternate between periods of near-normal brain function and dramatic lapses in attention and visual processing.
"It's as though it is both asleep and awake and they are switching between each other very rapidly," said David Dinges of the University of Pennsylvania School of Medicine. "Imagine you are sitting in a room watching a movie with the lights on. In a stable brain, the lights stay on all the time. In a sleepy brain, the lights suddenly go off."
