WebNov 22, 2024 · How does optogenetics work? Neurons are genetically modified to release light-sensitive membrane proteins, making the brain susceptible to selective photoexcitation. When stimulated by light, these proteins transport ions into (or out of) the targeted neurons, which excites electrical responses that trigger nerve impulses in the brain. WebOptogenetics is a modern research tool that gives neuroscientists an incredible ability to control neurons. It is a method of neuromodulation, which utilises genetic engineering; neurons are modified to express light …
