The neocortex, evolutionarily the most recent part of the brain, contains maps that represent sensory space. In a report in this issue, Kilgard and Merzenich show that the auditory map of the rat can be coaxed to change dramatically by stimulating a nucleus in the basal forebrain. In her commentary, Juliano discusses this work in the context of what is known about long- and short-term regulation of maps in the brain.
