Columbia EEG interface lets some unresponsive patients control a tone

A Columbia University team tested a non-invasive EEG brain-computer interface on 41 clinically unresponsive patients with acute brain injuries; about one in three controlled a beeping tone using brain activity alone. The study, published in Brain, is an early demonstration, not yet a way for patients to communicate specific needs or wishes.

Bottom line — All eight patients identified with cognitive motor dissociation controlled the tone, but the study does not establish that the interface can convey patients’ needs.

  1. The system used EEG electrodes already familiar in intensive care, rather than an implanted brain device, according to NR Times.

  2. Patients heard a tone and tried to change its frequency by imagining opening and closing their hands; bedside software analysed their brain signals in real time, EuropHospital reports.

  3. Quomi reports that 13 of the 41 patients controlled the system; all eight whose cognitive motor dissociation was identified in a separate assessment succeeded.

  4. Claassen’s team detected signs of hidden consciousness in 15% of unresponsive patients in a 2019 study using EEG and AI, according to NR Times.

  5. The study’s longer-term aim is to enable communication about basic needs such as pain or hunger; families suggested familiar voices and culturally relevant prompts, EuropHospital reports.
