Processing of natural scenes in the human pulvinar.

ABSTRACT: Theories of high-level visual processing and object recognition have typically focused on ventral visual cortex, often overlooking potential contributions of subcortical structures. The pulvinar, via extensive connections with visual cortex, is well-positioned to play a role in high-level vision. Here, we investigated how the pulvinar represents visual information using a high-resolution 7 T fMRI dataset of responses to tens of thousands of natural scenes. Encoding models targeting different stimulus features revealed a pulvinar region selective for bodies and faces presented in the contralateral visual hemifield. Complementary model-free analyses demonstrated that this region is co-active with body- and face-selective cortical areas during natural scene viewing. These findings challenge c
