Study Blames Mental Lapses on Sleep-deprived Brain Cells

These participants-who were otherwise healthy adults-had eight to 12 electrodes implanted just below their skulls on the surface of their brains, created to monitor the origin of their seizures. This could raise concerns over exhausted commuters driving into work after failing to get enough sleep, should someone cross the road in front of them.

The study participants were then asked to categorize images as fast as they can.

The scientists recorded the neuron activity in the medial temporal lobe of the brain while 12 people completed a facial recognition test, both before and after a full night without sleep.

Researchers also noticed sleep-like waves disrupting parts of the brain, nearly as if certain areas were dozing off and causing mental lapses of concentration, while other sections of the brain carried on running as normal.

The neurons unlike regularly responded very slowly and appeared to be very weak.

The worldwide team of scientists studied 12 people who were preparing to undergo surgery at UCLA for epilepsy.

Scientists have discovered that sleep deprivation causes your brain cells to switch off while awake - and it could happen to you while driving.

Janoris Jenkins Reinstated by Giants After Suspension for Rules Violation
New York Giants cornerback Janoris Jenkins has been reinstated after serving a one-week suspension for a violation of team rules. He was waived on September 2, re-signed on September 28, and was inactive for the Giants' game in Tampa Bay on October 1.

A Disney spokesman did not immediately respond to a request for comment while Fox declined to comment. With the company about to launch their own streaming service, that would be a huge boost.

This means that the ability of the neurons to process information and convert visual perception into their consciousness is greatly impaired by sleep deprivation. Fried explained that for example if a person is driving a auto and another person jumps in front of it, a sleep deprived person would have a different response than one who has had adequate sleep.

However, the link between tiredness and road traffic accidents is not a new one: it's estimated that hundreds of deaths and thousands of injuries in the U.S. alone are caused each year by drivers dozing off at the wheel and not being able to react fast enough. It takes longer for his brain to register what he's perceiving'.

Particular attention was paid to the neurons in the temporal lobe, where visual perception and visual memory are managed.

It was also found that brain cells that took longer to respond were associated with slower brain waves - such as those normally registered during sleep phases - and that this slow-motion activity was located in the same brain regions. "Select regions of the patients' brains were dozing, causing mental lapses", Fried said. The effects are similar to "drinking too much". He believes that there should be legal and medical standards in place to identify worn out drivers on the road.

The team plans to explore the benefits of a good night's sleep in more detail in the future and to uncover the mechanism responsible for the neuronal glitches that generate mental lapses.

Sleep deprivation has also been linked to obesity, depression and heart attacks, among other risks.

The research received support from the National Institute of Neurological Disorders and Stroke, the National Institute of Mental Health and other organizations.
