Abstract

We present a set of novel optogenetic devices for mice freely moving in cages. The purpose of the devices is to stimulate specific brain regions using light. The devices we have constructed consist of an electrical connector, cannula and micro- LED chip operating at 470 nm as light source for delivering light into the stimulated region of the mouse brain. We have also demonstrated light conversion from 470 nm to 590 nm by applying a silicate orange phosphor directly to the LED chip. The measured conversion efficiency is approximately 80% for ZIP595I phosphor. We discuss the properties of various forms of implant needles with respect to the ease of LED attachment and experimental validation of the constructed optogenetic implants.
