Imaging and ultrasound platforms expand non-invasive BCI ambitions

A reported fMRI image-reconstruction decoder reduces subject-specific calibration through two-branch modeling and synthetic training pairs, but its eight-person training base is small and it does not demonstrate imagined-content decoding. Bridge Neurotech’s reported $13.5 million financing, active first study, and Butterfly partnership remain commercialization signals without public human decoding metrics or independent clinical validation. Gestalt Technology’s deep-brain ultrasound claims and interview-level discussion of OPM-MEG and temporal-interference stimulation remain unvalidated as practical BCI capabilities.
