Optical brain-computer interface system and method

Abstract

An optical brain-computer interface system includes an acquisition unit, a preprocessing unit, a registration unit, a decoding unit, and a feedback unit. The acquisition obtains an optical neural signal from an optical acquisition device based on a preset interface. The preprocessing unit preprocesses the optical neural signal to obtain first neural image data, wherein the first neural image data comprises at least one layer of image data. The registration unit performs parallel registration on the first neural image data based on a preset first registration algorithm and a preset second registration algorithm to obtain registered second neural image data. The decoding unit decodes the second neural image data based on a preset region of interest to obtain representation data for neural activity. The feedback unit obtains a feedback control signal based on the representation data for neural activity for performing closed-loop feedback. Methods are performed using such a system.
