In the course of transduction, stimulus encounter by sensory receptors is converted into existing flow by way of ion channels to create the receptor prospective. This membrane depolarization is then transformed into a train of action potentials by voltage-gated ion channels to carry the sensory signal along the axon. dCIRL increases the mechanically-induced firing frequency of ChO neurons (Scholz et al., 2015). We reasoned that the light-gated cation channel Channelrhodopsin-2 (Nagel et al., 2003) [ChR2; retinal-bound channelopsin-2 (Chop2)] might be utilised to distinguish regardless of whether this effect was exerted in the amount of mechanosensory transduction or transformation. Simply because ChOs are also thermoresponsive (Liu et al., 2003), this approach necessitated an effective ChR variant to limit the heat generated by the required light intensities. We therefore screened for any ChR2 version that combines higher photostimulation efficiency (Dawydow et al., 2014) with excellent temporal precision.
