An expanding repertoire of circuit mechanisms for visual prediction errors

Abstract

Cortical responses to stimuli vary dependingon context and expectation. Adding insight into this process, Furutachi et al. recently demonstrated that higher-order thalamic input to visual cortex cooperates with interneurons to augment responses to unexpected stimuli, consistent with a body of literature implicating top-down modulation and local inhibition in predictive processing.
