... Synaptic transmission involves passage of an impulse from one neuron to another through the synaptic cleft. When an action potential reaches a synapse at the end of an axon, it causes the membrane there to depolarize. This results in Ca2+ voltage-gated channels there to open, allowing Ca2+ to diffu ...

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.
