Brain region mediates pleasure of eating

02:35 EDT 22 Aug 2017 | Medical Xpress

Providing the body with food is essential for survival. But even when full, we can still take pleasure in eating. Researchers at the Max Planck Institute of Neurobiology in Martinsried and the Friedrich Miescher Institute in Basel have characterized a type of neuron in the amygdala of the mouse brain that is involved in making eating rewarding. When given the choice, mice choose to activate these amygdala neurons. Artificially activating these neurons increases food intake even when the mice are not hungry. The neurobiologists have identified the neuronal circuitry underlying this behavior, raising the possibility that there could be cells with a similar function in the human brain.
