A Brain Interface Helps Patients Control Beeps

Name: __________________________ Date: __________________

Read the story

A Columbia study tested a noninvasive brain-computer interface in 41 unresponsive patients with acute brain injuries. Around one third controlled a tone after training.

Electrodes recorded brain activity without an implanted chip. Researchers hope to develop communication tools; ordinary conversation was not demonstrated.

Read and practise

1. How widespread was success in this small study?

   1. All patients without training
   2. Exactly half of all hospital patients
   3. Around a third of the 41 patients

2. What distinguishes this system from a brain implant?

   1. It recorded activity with electrodes without a chip
   2. It required an implanted chip
   3. It did not record brain activity

Your turn

Explain why controlling a tone is a step towards communication.
