Rhythmic interactions between the mediodorsal thalamus and prefrontal cortex precede human visual perception

Abstract

How the thalamus and the cortex interact in the context of perception remains largely unclear. Here, the authors show that rhythmic activity in the human mediodorsal thalamus and prefrontal cortex interact to predict whether a near-threshold visual stimulus will be seen, contradicting the traditional view that the thalamus is a simple relay.
