title: Beta and gamma rhythms go with the flow.
abstract: Information flows through visual areas in opposite directions during "bottom-up" intake of current stimuli and "top-down" processes such as attention or memory. In this issue of Neuron, Bastos et al. (2015) report that rhythms of different frequencies coordinate bottom-up and top-down information streams.
