Episode notes
Cognitive Densification
- The world will become more conceptually and cognitively dense.
- Dean W. Ball worries some will struggle to keep up with this increasing complexity.
Neural Technology Basics
- Neural technologies use sensor fusion and signal processing of brain biomarkers.
- EEG measures electrical fields, while MEG measures magnetic fields, both generated by brain activity.
EEG's Surprising Effectiveness
- EEG surprisingly works non-invasively, reading signals from the brain's surface.
- Consumer EEG devices can predict seizures and Parkinson's with high accuracy.
