Humans have certain instinctive fear reactions to things that won’t actually harm us—we might jump at a too-loud noise or ...

Studies reveal important principles through which the brainstem regulates satiation, and begin to shed light on the neural determinants of meal size.

Researchers have identified a group of brain cells in mice that play a key role in regulating appetite. These neurons, ...

“Optogenetics revolutionized how we all do experimental neuroscience in terms of exploring circuits,” says Thomas McHugh, a neuroscientist at the RIKEN Brain Science Institute in Japan. However, this ...

Researchers have uncovered a neural mechanism in the brains of mice that enables them to override instinctive fear responses; dysfunction in this mechanism may contribute to inappropriate or excessive ...

Neurons in the brains of mice tell them to stop eating when they’ve had enough food – and since people probably have the same ...

Female mice demonstrated similar shifts under the ... while inhibition blocked the stress-induced preference shift. In females, optogenetic stimulation of VTA-NAc projections with rapid, burst ...
