Binocular battles on multiple fronts

The visual percept fluctuates over time when dissimilar patterns are shown to the two eyes (binocular rivalry). Where in the brain are the corresponding fluctuations of neuronal activity? Conflicting results from studies using various techniques have rendered this question unresolved at present. A recent paper by Wilson, however, promises to reconcile previous disagreements, as it demonstrates that rivalry can be located at different stages of the neuronal hierarchy, depending on the nature of stimulation.
