Biologists learned to turn off hunger

An international team of biologists has discovered a way to fight the feeling of hunger from the planet. Scientists found in a certain region of the brain that encodes signals of hunger and satiety, and learned to manage his work.

Biologists conducted an experiment with mice and deprived them of their feelings of hunger and all associated annoying feelings. "One of the reasons that diets are so difficult to adhere to, is what we experience in the highest degree unpleasant feelings associated with the constant hunger. Our results show that the inclusion of this area is a pleasant feeling and reduces the feeling of hunger almost zero in mice. It makes similar therapy is equivalent in strength to ordinary diet, but without the annoying related feelings," said Bradford Lowell of Harvard University.

Lowell and his colleagues during the last 2 decades of work exploring those parts of the brain, which most likely are related to appetite, feelings of fullness and hunger and other gastronomic feelings and traits of a person. They are found in the hypothalamus of the special group cell transplantatio - AgRP-neurons, which are responsible for almost all food feelings. Research workers learned their "insert" and to encourage gluttony, and with the "shutdown" had difficulty.

But now the problem is solved, and at the moment Lowell and his colleagues are working to create medicines that could enter the brain and to enable this group of nerve cells. If they can do it, then, according to them, they will create a more pleasant alternative for diets that can help people to fight with obesity and overweight.
