Anomalous localizations of mechanical and electrical cutaneous pulses are produced when widely separated bodily points are successively stimulated with trains of taps. The observer experiences a manifold of discrete "phantom" impressions connecting the points actually touched. The theoretical basis for this perceptual phenomenon is not understood, but some boundary conditions are specified.
