Optogenetics comprises a growing family of related techniques for the optical interrogation and control of excitable cells. Combining genetic targeting with light delivery systems makes it possible to drive or silence subpopulations of neurons and the related behaviours, with a high spatiotemporal precision. Since optical manipulation is fast, selective, and minimally invasive, it provides distinct...
The demonstration will presents a battery powered multichannel wireless optogenetic headstage providing neural recording and optical stimulation capabilities simultaneously. The proposed headstage, which is entirely built using commercial off-the-shelf components, includes 32 electrophysiological recording channels and up to 32 high-power optical stimulation channels. It can process 32 neuronal signals...
Fiberless optoelectrodes are an emerging tool to enable brain circuit mapping by providing precise optical modulation and electrical monitoring of many neurons. While optoelectrodes having an on-board light source offer compact and optically efficient device solutions, many of them fail to provide robust thermal and electrical design to fully exploit the recording capabilities of the device. In this...
Optogenetics is an emerging technology that allows targetable, fast control and readout of specific neural populations in complex brain circuits. The intricate and complex interactions between different neural populations require novel implantable neural interfaces that are capable of manipulating and probing targeted neurons at multiple sites and with high spatiotemporal resolution. Advanced microtechnology...
In this paper, we present a light-weight, wireless optogenetic headstage which provides optical neural stimulation and electrophysiological recording alongside on-the-fly neural signal processing. The proposed headstage is suitable to conduct long terms in-vivo experiments with small freely moving transgenic rodents, and features two implantable LED-coupled optical fibers and two electrophysiological...
