Translating Expectation into Visual Selection through a Beta-Synchronous Fronto-Parietal Neural Subnetwork.

Top-down expectancy critically determines how fast sensory inputs are processed. Fiebelkorn & Kastner show that translating expectancy into fast stimulus processing is mediated by a subnetwork of beta-synchronized neurons across the fronto-parietal attention network. This finding suggests that precise spike timing determines how efficient fronto-parietal activity selects visual inputs.
