Abstract

From the top The act of shifting the focus of one's attention prepares the brain for a new processing task. How this ‘top down’ control influences the neurons processing the stimulus has been extensively studied in the visual system of primates. New work, in the well studied auditory system of the barn owl, shows that artificial stimulation of forebrain circuits enhances auditory processing in a similar way. So top-down modulation of this type may be a common strategy for brain attention systems.
