... From the beginning of the 20th Century until the 1990s, it was stated that neurons DID NOT proliferate. The fact that they COULD NOT proliferate did not exclude the possibility of proliferation under “specific conditions.” In fact, the CNS has a considerable regenerative potential depending on ...

Channelrhodopsin
Channelrhodopsins are a subfamily of retinylidene proteins (rhodopsins) that function as light-gated ion channels. They serve as sensory photoreceptors in unicellular green algae, controlling phototaxis: movement in response to light. Expressed in cells of other organisms, they enable light to control electrical excitability, intracellular acidity, calcium influx, and other cellular processes. Channelrhodopsin-1 (ChR1) and Channelrhodopsin-2 (ChR2) from the model organism Chlamydomonas reinhardtii are the first discovered channelrhodopsins. Variants have been cloned from other algal species, and more are expected.
