AI Literally Reads Minds: Tribe V2, fMRI Data Neural Prediction & In-Silico Neuroscience

For decades, neuroscience relied on expensive fMRI scanners to approximate human cognition through noisy blood-flow measurements. This video breaks down Meta’s Tribe V2 foundation model, a multimodal AI system trained on over 1,115 hours of brain scans across 720 subjects. Using Llama 3.2, Wav2Vec BERT, and V-JEPA 2, the architecture predicts synthetic neural activity across 70,000 brain voxels without requiring a physical scanner. The discussion covers multimodal transformers, modality dropout, simulation-based inference, neuromarketing implications, inverse stimulus design, and the rise of in-silico neuroscience. It also explores how AI may become a cleaner biological sensor than the human body itself.
