“…The restoration of abilities following a lesion of a nervous structure depends on many factors:the nature of the neural structure, the extent of the lesion, the age at which the lesion was done, and the sensorimotor experience before and after the lesion (Auvray, Caston, Reber, & Stelz, 1989;Caston et al, 1995;Igarashi, Levy, O-Uchi, & Reschke, 1981;Jeannerod & Hecaen, 1979;Lacour & Xerri, 1980;Petrosini, 1983;Precht, 1983;Putkonen, Courjon, & Jeannerod, 1977;Zion, Auvray, Caston, Reber, & Stelz, 1990).
