Summary
A study has shown that brain implants, known as brain-computer interfaces (BCIs), can decode the internal monologue of paralyzed people, raising privacy concerns. These devices can translate imagined speech, not just attempted speech, into words with significant accuracy, utilizing artificial intelligence.
Key Facts
- Brain-computer interfaces (BCIs) help paralyzed people speak by decoding signals from the brain.
- New research shows BCIs can translate a person's inner thoughts, or imagined speech, into spoken words.
- The study was published in the scientific journal Cell.
- BCIs work by using tiny electrode arrays placed on the brain’s motor cortex.
- Researchers achieved up to 74% accuracy in decoding sentences from inner speech.
- The enhancement may allow faster and easier communication for users but also brings up privacy concerns.
- The study involved monitoring brain signals from four people already using BCIs.
- There is concern that inner thoughts could be unintentionally revealed when using these devices.
