were able to control the three behaviours by switching the neurons on and off in a part of the animals’ brainstem called the median raphe nucleus. The findings are reported in Nature today 1.

We focused our study on the median raphe nucleus (MRN), a brainstem structure that integrates cognitive, affective (emotional) and motivational signals, although its role in decision-making ...

The arcuate nucleus (ARC) in the hypothalamus and area postrema in the brainstem have direct access to circulating hormones relaying information about satiety, adiposity and caloric intake.

Scientists have uncovered a dedicated brain circuit that distinguishes between direct fear and fear learned by observing ...
