A compressed hierarchy for visual form processing in the tree shrew.

ABSTRACT: Our knowledge of the brain processes that govern vision is largely derived from studying primates, whose hierarchically organized visual system¹ inspired the architecture of deep neural networks². This raises questions about the universality of such hierarchical structures. Here we examined the large-scale functional organization for vision in one of the closest living relatives to primates, the tree shrew. We performed Neuropixels recordings^3,4 across many cortical and thalamic areas spanning the tree shrew ventral visual system while presenting a large battery of visual stimuli in awake tree shrews. We found that receptive field size, response latency and selectivity for naturalistic textures, compared with spectrally matched noise⁵, all increa
