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

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

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 ...

Researcher suggest findings could help understand what happens in the brain when fear response regulation is impaired.

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 ...

“It was a pretty remarkable experiment,” says Deisseroth. Using optogenetics, the researchers turned off cells in the posterior insular cortex and the prefrontal cortex in some mice while stimulating ...

As a postdoctoral fellow in the laboratory of Susumu Tonegawa at MIT, Liu and graduate student Steve Ramirez used optogenetic techniques to identify the neurons involved in encoding fear memories in ...

To survive in complex and unpredictable environments, humans and other animals need to learn to predict the consequences of ...
