Chronos opsin
WebChannelrhodopsins are nonspecific cation channels that depolarize upon blue light illumination. These light-gated ion channels were isolated from green microalgae of the genus, Chlamydomonas. Structurally, they have a seven-transmembrane region and a C-terminal extension. WebAnimal opsins are G-protein-coupled receptors and a group of proteins made light-sensitive via a chromophore, typically retinal. When bound to retinal, opsins become Retinylidene proteins, but are usually still called …

Surprisingly, neurons did not exhibit narrow-band resonance in specific frequency-ranges, and showed reliably phase-locking up to 140Hz. Strong phase-locking at high frequencies reflected non-linear input/output transformations, with neurons firing ...
