Scientists from the University of Manchester have discovered special cells which are present in the body that seem to be responsible for regulating a person's body clock.

They are hoping that this clue may help people in fighting jet lag.

The new study has found a completely different from the belief that these cells remain inactive during the day.

Professor Hugh Piggins, lead researcher and an expert in neuroscience at the university believes that the research will permit a whole new approach to help tune our daily clock.

Researchers believe that the body clock is regulated by the brain by firing more cells during daylight and very few during the night.

"The traditional model said the clock and the brain communicated to the rest of the brain via the number of electrical impulses that the brain cells were producing," The BBC News quoted Piggins saying.

It is found that brain cells contain a main gene which is called perl and it allows them to sustain unusually high levels of excitability.
