Neuroscientists examine how ‘decision uncertainty’ signals drive rapid changes in pupil size

Advances in optogenetics

Optogenetics is a way of introducing information into the brain using light, it targets specific cells or connections across the brain. It is fast, like brain signaling, and helps you communicate with neural circuitry in a language more similar to what is normally used within the brain.
