Sep 10, 2025 NPR brain correspondent Jon Hamilton shares insights on the fascinating world of brain-computer interfaces (BCIs), which connect our brains to computers. He discusses how BCIs can help those with paralysis regain mobility and communication. Hamilton highlights the ethical dilemmas of brain privacy as advancements allow for the detection of thoughts. The conversation touches on the challenges of FDA approval and the potential for misuse, raising questions on how we protect our inner monologues in an increasingly interconnected world.

Episode notes
First Real BCI Demo
- In 2004 Matt Nagel, paralyzed from a stabbing, used BrainGate to move a computer cursor with his thoughts.
- He opened email and demonstrated early BCI capability by controlling a cursor via neural signals.
Technical Progress In Implant Design
- Modern BCIs are wireless, use many more electrodes, and reach higher accuracy by listening to more neurons.
- They now enable robotic arm control and can even provide a sense of touch via feedback to the brain.
ALS Patient Speaking With BCI
- Casey Harrell, who has ALS, uses a BCI to speak through an artificial voice because he can no longer produce words physically.
- His BCI decodes motor cortex signals tied to attempted speech and turns them into understandable audio.
