OMNI , ,  advances state-of-the-art in implantable closed-loop neuromodulation systems by enhanching the ability to chronically record neural activity and perform closed-loop stimulation at the network level. The large number of channels, low power consumption, and reduced number of implant wires allow OMNI to cover more brain regions, simplify implantation, and operate continuously for longer periods of time. Through its modular and distributed approach to neuromodulation, OMNI is capable of addressing complex disorders that manifest in multiple brain regions at the systems level and require a dynamic approach to the therapy, such as major depression and post-traumatic stress disorders.
OMNI has been tested in vitro in a saline setup (shown below). In vivo testing with the integrated non-modular version of OMNI (missing reference) has also been done in a macaque monkey (see WAND project) in collaboration with Profs. Jose Carmena’s and Rikky Muller’s labs.
This project was a collaboration between Profs. Jan Rabaey and Elad Alon groups at UC Berkeley (CM, AM, and system integration), Cortera Neurotechnologies (NM chip design ), Lawrence Livermore National Laboratory (packaging and electrode fabrication) and UCSF Department of Neurological Surgery.
