In this technical report, the authors describe a new, red-shifted variant of channelrhodopsin (called red-activatable channelrhodopsin or ReaChR) that shows faster kinetics and greater photocurrents than currently available red-shifted probes. In addition, they show that ReaChR can be activated in awake mice through the intact skull.
This technical report describes a method to clear fixed brain tissues while allowing for fluorescent dye tracing and retaining cellular morphology. The authors demonstrate the utility of the technique by obtaining a wiring diagram for sister mitral cells.
This Technical Report describes light-activatable metabotropic glutamate receptors based on synthetic photoswitchable tethered ligands, and demonstrates optogenetic control of G protein–coupled receptor activity in neurons in vivo and ex vivo.
