WebOct 14, 2015 · How does optogenetics work? First introduced around 2005, optogenetics involves genetically engineering neurons to express light-sensitive proteins on their membranes. With those proteins... 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.
