New study finds conserved visual alignment across species

Researchers have investigated the alignment between learning rules and brain activity across species, comparing human fMRI data with macaque electrophysiology. They found that early visual cortex alignment is consistent between humans and macaques, with spike-timing-dependent plasticity and predictive coding showing the highest correlation. However, alignment in higher visual areas like the inferotemporal cortex (IT) did not show a clear cross-species correlation, suggesting that model capacity and training data are more critical factors for IT alignment than the specific learning rule used.
