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. WebHow does optogenetics work? Algae found in ponds and lakes contain light sensitive proteins called rhodopsins. These rhodopsins become active when exposed to light. For example, when a nerve cell containing rhodopsins is exposed to a certain colour of light, the rhodopsins becomes stimulated and change shape which in turn changes the activity ...
