Postnatal development of corticocortical connections.

In the course of normal development transitory corticocortical projections are formed within each hemisphere and between the two hemispheres. The organization of the transitory projections and the main events in their elimination have been investigated. Experiments on visual areas of the cat indicate that the elimination/stabilization of a fraction of the juvenile projections depends on activity.
