Chronos opsin
WebOct 18, 2016 · Optogenetics provides a unique approach to remotely manipulate brain activity with light. Reaching the degree of spatiotemporal control necessary to dissect the role of individual cells in neuronal networks, some of which reside deep in the brain, requires joint progress in opsin engineering and light sculpting methods. Here we investigate for … WebChronos enables high frequency responses without adaptation High-frequency blue light stimulation (2 ms pulses at 40 Hz for 1 s) was applied with the Lumos to channelrhodopsin-expressing (ChR2) primary rat neurons. The light-evoked neural response showed adaptation with reduced responses to later pulses in the train.
