A Differential Circuit via Retino-Colliculo-Pulvinar Pathway Enhances Feature Selectivity in Visual Cortex through Surround Suppression


Fang et al. show that the lateral posterior nucleus of thalamus, the rodent homolog of pulvinar, enhances feature selectivity in primary visual cortex via subtractive surround suppression mediated by inhibition from cortical layer 1 driven by the bottom-up retina-SC-LP-V1 pathway.
