What Are Optogenetics?

The video introduces optogenetics, a technology that uses light to control neurons. It explains how neurons communicate through electrical signals and how the discovery of channelrhodopsin, a light-sensitive protein, has enabled scientists to manipulate these signals. The video discusses the applications of optogenetics in studying behavior, understanding brain functions, and potential medical uses like light-based pacemakers. It highlights ongoing research and the vast possibilities of this technology, while also cautioning against its misuse.
