AI & the Brain.
Where neuroscience and artificial intelligence meet, covered the same way as everything else here: verified, and without the hype.
This collection follows a few distinct lines where the two fields touch. Every item links straight to the real brief or article, and nothing here is invented.
- AI used to study brains. Models that read scans or estimate what a scarcer, more specialized tool used to measure directly.
- Brains held up against AI models. How patterns of real neural activity compare with the representations inside systems like GPT-2.
- Brain-inspired AI. Ideas drawn from how the brain works that shape how models are built and understood.
- The clinic, where it applies. What it means, and what still has to be proven, when a model is pointed at a patient.
New here? Start with What does an fMRI actually measure? — the plain-language ground that the imaging and modeling work in this collection is built on.

A Model Estimates Alzheimer’s Tau From a More Common Brain Scan
A machine-learning model trained on how the brain uses energy tries to estimate Alzheimer’s tau burden from an ordinary FDG-PET scan, instead of the specialized tau PET most clinics don’t have. A clear case of AI pointed at a clinical reading, with its limits stated plainly.

The Hippocampus Carries a Map of Meaning That Resembles an AI’s
Recording from single neurons as people listened to spoken stories, researchers found the hippocampus holds a map of word meaning that lines up most closely with the word embeddings inside the language model GPT-2. A direct comparison of brain and model representations.

Can a brain implant read the voice in your head?
A brain implant caught sentences a person only imagined, decoded by a model trained on their own neural activity. The same study shows how limited, and how careful, that reading has to be.
