Researchers identified two brain areas in mice that helped the animals learn to suppress their instinctive fears of predators ...

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 ...

More than a decade ago, scientists developed optogenetics, a method to turn cells on and off with light. The technique allows scientists to spur or suppress cells' electrical activity with just the ...

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 ...

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 ...

Astrocytes play a crucial role in mediating surgery-induced anxiety in mice through modulating GABAergic signaling in the ...

To achieve this, they used genetically modified mice that allowed for precise control of MCH neurons. They employed optogenetics, a technique that uses light to activate or inhibit specific ...
