Brain clock reset button found.

ISLAMABAD -- Scientists have found a "reset button" for our biological clock, paving the way for more effective treatment of jet lag, the negative health effects of shift work and seasonal affective disorder (SAD).

The discovery was made by a group of researchers at the Vanderbilt University, Press Tv reported.

During the research, the group discovered they could artificially stimulate the brains of mice and change their natural waking and sleeping cycles, without using the presence of light.

They carried this out with the stimulation or suppression of neurons in the brain's suprachiasmatic nucleus (SCN), which can effectively reset the biological clock.

The SCN is a small region inside the hypothalamus which regulates a 24hours rest and activity cycle and helps animals know when they should eat or rest.

According to neuroscientists, mice have a biological clock which is almost identical to that of humans with the difference that it is finetuned for nocturnal life.

By assessing the neurons response to the light, the scientists were able to measure and control the rate at which neurons fired in the SCN.
