Bi-stable neural state switches : Article : Nature Neuroscience
Another channelrhodopsin breakthrough from Deisseroth’s lab. This time light is not required to keep the channel open. Light merely triggers opening and closing behavior. Blue-shifted light opens channels and red-shifted light closes them. This looks like another potentially powerful neurotechnology for interrogating circuits and systems.

Exciting! We’re giving a Wiley Prize to the scientists who discovered channelrhodopsins, so it’s awesome to see these being applied.
