WebChronos and Chrimson likewise evoked an initial deflection of the LFP signal (Fig. 5B,C). However, neither Chronos nor Chrimson activation of excitatory neurons evoked the characteristic sustained high-frequency LFP activity observed following ChR2 stimulation of the same population of neurons.

WebOur results demonstrate that Chronos has the ability to drive the auditory system at higher stimulation rates than ChR2 and may be a more ideal opsin for manipulation of auditory pathways in future optogenetic-based neuroprostheses. This article is part of a Special Issue entitled "Lasker Award". Web1. Opsin-linked GFP fluorescence demonstrates Chronos expression throughout the injection-targeted dorsal CN with labeling in all 3 CN subdivisions. Chronos expression contiguously extends routinely into the ventral CN and variably on into the auditory nerve. Extension medially into the inferior cerebellar peduncle is also occasionally noted. 1.
