The paper explores whether brain-computer interfaces truly interpret neural intent or simply fit statistical models to signals.
Discusses the bidirectional adaptation between neural signals and decoding mechanisms.
Examines the implications of dimensionality reduction and neural drift on BCI performance.
Proposes a framework for enhancing BCI systems through co-adaptation and algorithmic developments.
Highlights the importance of treating neural drift as a design target for BCIs.
Emphasizes that modern BCIs are not just black boxes but systems that leverage scientific principles for control.
Outlines four practical research priorities for improved BCI functionality and adaptation.
