Propagating Waves in Visual Cortex

Spatiotemporal patterns of cortical activation occur superimposed upon sensory, motor, and cognitive maps. The papers by Benucci et al. and Xu et al. in this issue of Neuron demonstrate that visual responses propagate in space and may serve to link different visual areas. This is an important step toward understanding how cortical maps relate to activation patterns, a prerequisite to understanding visual cortex function
