Cross-species RSA: same learning rules (BP, PC, STDP, FA) tested against both human fMRI and macaque electrophysiology [P]

In three linesCross-species comparison of learning rules (BP, PC, STDP, FA) tested on human fMRI and macaque electrophysiology (V1/V2/V4/IT). STDP and PC dominate V1/V2 (ρ ≈ 0.30/0.28), conserving human pattern. In IT, alignment depends on model capacity (ResNet-50: ρ ≈ 0.25) rather than learning rule. Code and two papers (arxiv 2604.16875, 2605.22401) available.
