How higher-order thalamic feedback modulates sensory-evoked cortical activity is not fully understood. This study reveals that synaptic feedback from the thalamus selectively increases the excitability of distinct cortical neurons through NMDARs and mGluR-mediated modulation of potassium channels, thereby enhancing sensory processing.
