Inductive Light Generator (ILG)

This invention is a practical extension of Stanford docket S05-170 (photosensitive proteins Channelrhodopsins) and describes an implantable, light-generating device for the optical stimulation of neural cells. Essentially an optical electrode, this is intended to be a next-generation method providing deep brain stimulation (DBS). Importantly, this neural interface is designed to permit neuron-type-specific modulation. For example, motor fibers might be recruited while leaving immediately adjacent pain fibers undisturbed or excitatory neurons might be harnessed without affecting inhibitory neurons in a region. Targeted, temporally-precise control of neuronal subtypes may enable neuromodulation with fewer side effects and more robust therapeutic efficacy.
