30 snips
Aug 22, 2025 Jean-Rémi King, a neuroscience researcher at Meta’s Paris lab, joins Neil deGrasse Tyson and co-hosts to explore the potential of decoding thoughts using AI. They discuss the groundbreaking technology behind interpreting brain signals, along with the ethical implications of mind-reading. Insights into the complexity of individual cognition and the challenges of knowledge transfer highlight how unique brain processes affect communication. The conversation also dives into the boundaries of current mind-reading tech and the crucial need for responsible development in this evolving field.

Episode notes
AI As A Model For Brain Research
- Meta's FAIR lab combines neuroscience and AI to both understand the brain and improve AI algorithms.
- They use AI as a modeling framework, not just a data-crunching tool.
Why Noninvasive Signals Are Selective
- EEG and MEG measure tiny electric and magnetic fields generated by aligned neurons near the cortex.
- Only spatially aligned pyramidal cells produce measurable macroscopic signals at the scalp.
Imaging Tradeoffs: Time Versus Space
- fMRI measures blood flow as a proxy for neural activity and has much slower temporal resolution than EEG/MEG.
- Different imaging modalities give different trade-offs between spatial and temporal detail.
