"Programming" the Brain
We are developing next-generation brain computer interfaces that:
- Record large, high-density, brain cell populations and further our understanding of how the brain encodes information at the cellular level, known as the neural code.
- Mimic the neural code by selectively stimulating individual brain cells to remedy various medical conditions such as blindness, epilepsy, and mental disorders.
Programming the brain is the intersection of neuroscience, electrophysiology and biophysics for cell-specific stimulation, algorithm design for emulating the neural code, and hardware-software co-design for a full BCI system. Currently, all work is in collaboration with the Stanford Artificial Retina Project spear-headed by the Chichilnisky Lab, focused on creating a retinal prosthesis.
