Clock predicts danger imminent

Researchers have successfully developed the first type of wristwatch-like sensor that acts as an EEG, which can accurately predict seizures or impending seizures.

This device measures the flow of electricity through the skin that is associated with sweat from the body. The activity of the sweat glands depends on the sympathetic nervous system, which controls the psychological response. When there is something, such as the chill feeling running down the back, the conductivity of the skin will increase significantly.

Rosalind Picard and colleagues at the MIT Media Lab in Cambridge, Massachusetts have developed a wrist strap that studies the emotional states of autistic children who may not always be able to talk to them. People around what their bodies are feeling.

Many children with autism suffer from convulsions, Picard said, and the consequences are so severe that the number of deaths each year is greater than in cases of breast cancer.

Brain wave activity will be blocked after the seizure passes. EEG can measure brain activity, but requires a lot of complex sensors attached to the scalp, so we can not carry it 24 hours a day.

This new device is capable of receiving signals earlier than EEG because EEG can only work in the cerebral cortex. The most obvious sign occurred up to 20 minutes before the onset of seizures.

"If you have epilepsy, you will be very afraid of sleep at night ," she said. 'With this bracelet, you can know and call for help before the danger comes.'
