Cross-Species RSA Reveals Conserved Early Visual Alignment but Divergent Higher-Area Rankings Across Human fMRI and Macaque Electrophysiology
Researchers have published a study comparing how different learning rules in artificial neural networks align with visual processing in both humans and macaques. The study found that early visual cortex alignment was conserved across species, with artificial neural networks showing higher correlation with macaque electrophysiology data than with human fMRI data. However, at higher visual areas like the IT cortex, the alignment rankings of learning rules diverged significantly between species, suggesting that model capacity and training data play a larger role than the specific learning rule in these areas.
