For the first time, patterns of excitation waves found in brain's visual processing center

Neuroscientists have long believed that vision is processed in the brain along circuits made up of neurons, similar to the way telephone signals are transferred through separate wires from one station to another. But scientists at Georgetown University Medical Center discovered that visual information is also processed in a different way, like propagating waves oscillating back and forth among brain areas. Their findings are published in the July 5 issue of the journal Neuron.
