Applied fMRI covert awareness detection

By Adrian M. Owen, Martin M. Coleman, Melanie Boly, Matthew H. Davis, Steven Laureys, and John D. Pickard

Summary

A patient diagnosed as vegetative was instructed to imagine playing tennis (activates SMA) and walking through her home (activates parahippocampus, etc.). Brain activity was indistinguishable from healthy controls — proving behavioural unresponsiveness ≠ unconsciousness.

Why It Matters

Shattered diagnostic certainty; launched fMRI/BCI covert cognition detection; raised urgent ethical issues about end-of-life decisions.
