Abstract

That attention is a rhythmic process has received abundant evidence. Here, the authors reveal the natural sampling rate of auditory and visual periodic temporal attention. Both are antagonistically modulated by overt motor activity, a result generalised in a dynamical model of coupled oscillators.

Abstract

The fact that feed-forward and top-down propagation of sensory information use distinct frequency bands is an appealing assumption for which evidence remains scarce. Here we obtain human depth recordings from two auditory cortical regions in both hemispheres, while subjects listen to sentences, and show that information travels in each direction using separate frequency channels. Bottom-up and top-down propagation dominates in γ- and δ–β (, Sensory processing relies on information transfer in cortical hierarchies. Using depth recordings of neural activity obtained while individuals with epilepsy listen to spoken sentences, the authors show that ascending and descending information is propagated between cortical regions through distinct neural frequencies.
