Researchers at Karolinska Institutet in Sweden have identified a brain circuit that can drive repetitive and compulsive behaviors in mice, even when natural rewards such as food or social contact are ...

The goal of this study was to create and validate a non-invasive optogenetic pacemaker that could directly pace cardiomyocytes and control heart rhythms. With a rising interest in the Heart-Brain axis ...

Researchers at the University of Geneva, together with colleagues in Switzerland, France, the United States and Israel, describe how optogenetic control of brain cells and circuits is already steering ...

High-resolution extracellular electrophysiology is typically used to record from neurons in order to understand brain function. Combining electrophysiology with optogenetics allows researchers to test ...

Before optogenetics emerged, researchers studying neural signaling relied largely on voltage- and calcium-sensitive dyes, as well as probes designed to detect changes in pH. Combined with the use of ...
