Tests in mice using optogenetics showed that when these identified neurons were activated by the light, the mice ate much smaller meals. The intensity of the activation determined how quickly ...

Using optogenetics (inactivating specific brain regions using light), the researchers were surprised to find that frontal cortical regions of the brain—known for tongue control in mice—were ...

A cardiac ventricular arrhythmia can be converted to a normal sinus rhythm (white line) by using a sequence of light pulses (blue line) in an optogenetic mouse heart. Applying such pulsed light ...

works on mice. The study is also the first to combine the use of two investigative techniques called electrophysiology and ...
