Earlier research revealed that the amygdala, an almond-shaped brain structure most commonly linked to fear, was active when rats were hunting and feeding. To see whether this brain region was actually ...

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 ...

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 ...
