What is CortexLab and how does it benchmark AI models?

CortexLab's an open-source Python toolkit on TRIBE v2, using RSA/CKA/Procrustes to align AI features with fMRI brain predictions, plus stats like p-values and CIs per brain region.

Which AI models score best on brain alignment in CortexLab?

Early synthetic runs show V-JEPA2 slightly ahead in RSA (+0.0121), LLaMA high in CKA (0.8848), but no model hits significance — highlights need for real fMRI data.

Is CortexLab ready for production AI or neuroscience research?

Yes for analysis pipelines and dashboards; it's got real-time streaming and interpretability. Needs community input on metrics and real datasets for full rigor.
