Episode notes
Brainwaves to Text
- Scientists turned brain activity into text by tracking neural data from volunteers with implanted electrode arrays.
- The system learned to map brainwaves to spoken words, showing potential for aiding communication in patients unable to speak.
System Limitations
- The system is limited, performing well on trained sentences but struggling with new ones.
- It likely relies on a mix of memorization, word identification, and general pattern recognition.
Predicting Life Outcomes
- Researchers tried predicting children's life outcomes using 13,000 data points from 4,000 families over 15 years.
- No model, simple or complex, achieved reasonable accuracy, highlighting the complexity of such predictions.
