Title
Live Demonstration: A Wireless Headstage Enabling Combined Optogenetics And Multichannel Electrophysiological Recording
Abstract
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 in real-time with high compression ratio using an FPGA performing spike detection and data compression in-situ for fitting 32 channels over a low-power 2.4-GHz ISM data link (compression ratio > 500), hence greatly decreasing power and complexity. The presented headstage is small and lightweight enough for enabling optogenetic in-vivo experiments with freely moving transgenic rodents.
