How neurons autonomously regulate their excitability
Nerve cells can regulate their sensitivity to incoming signals autonomously. A new study led by the University of Bonn has now discovered a mechanism that does just that. The German Center for Neurodegenerative Diseases and ...

Researchers describe a mechanism in mice that underlies local dopamine release in the brain
When we initiate an action in our everyday lives—chasing after a runaway napkin or getting out of the car—the brain releases a chemical messenger called dopamine that helps regulate the brain area that controls this action.

Researchers discover new spontaneous signaling pathway in the brain
The brain is constantly firing and controlling purposeful action potentials—electronic messages used by neurons to communicate with each other and allow the brain to function. Conversely, the way spontaneous neural communication ...
