Space-Specific Deficits in Visual Orientation Discrimination Caused by Lesions in the Midbrain Stimulus Selection Network (Current Biology)

Selective attention depends on the ability of the brain to route information according to task demands. Knudsen et al. find that small lesions placed at key nodes in a midbrain network in chickens interfere with their ability to route information about the orientation of visual contours for making perceptual decisions.
