Empty-Stomach Intelligence

Empty-stomach intelligenceAccording to researchers, staying hungry actually make a person smarter.

A team led by Tamas Horvath, chairman of Yale’s comparative medicine program, had been analyzing the pathways followed in mouse brains by ghrelin, a hormone produced by the stomach lining, when the stomach is empty. To the scientists’ surprise, they found that ghrelin was binding to cells not just in the primitive part of the brain that registers hunger (the hypothalamus) but also in the region that plays a role in learning, memory and spatial analysis (the hippocampus).

The researchers then put mice injected with ghrelin and control mice through a maze and other intelligence tests. In each case, the biochemically “hungry” mice — mice infused with ghrelin — performed notably better than those with normal levels of the hormone.
