Brain-Computer Interfaces and the Interplay between Bio-electronics, Neuroscience, and Applied Probability

In this talk, we use the lens of brain-computer interfaces to discuss the interplay between bio-electronics, neuroscience, and applied probability. We begin with a discussion of recently developed epidermal electronics that enable ways to record neural signals on the surface of the forehead using ultra-thin, flexible, wireless electronics that can be embedded in a temporary tattoo. We demonstrate the ability to record high-quality EEG brain markers in a collection of different paradigms. We then consider closed-loop brain-computer interfaces, where the goal is to sequentially identify the most useful subsequent stimuli to the user, given previously acquired neural signals, to maximize a performance objective. We show how using appropriate applied probability and feedback information theoretic approaches lead to easy-to-use solutions that enable unobtrusive applications for BCIs for clinical applications and beyond.
