Mind-blowing science: ‘Star Wars-style’ holograms to communicate with the brain
Investigators supported by the Chan Zuckerberg Biohub San Francisco are imagining the future of neuroscience
Now a trio of scientists at UC Berkeley are taking brain–machine interfaces to a new level, with a powerful platform that incorporates optogenetics and computer-generated holography in a way that shows promise as a high-throughput, high-precision technique for communication with the brain. Muller is developing ultrafast spatial light modulators; they’re typically slow components used in computer display technologies, but she’s speeding them up using fast-switching piston motion MEMS (micro-electromechanical system) micromirrors coupled to an integrated-circuit driver. Waller got interested in neuroscience after meeting Adesnik, a professor in UC Berkeley’s Department of Molecular and Cell Biology, through a mutual friend, while Muller had previously co-founded a neurotech startup.
