Abstract
Experimental transection of the corpus callosum in animals and callosotomy practiced in human adults for therapeutic purposes have led to the description of the disconnection syndrome. Typically, adult patients or animals who undergo a callosal section show a permanent deficit in interhemispheric transfer and integration of sensory and motor functions (for reviews, see Sperry et al., 1969; Gazzaniga, 1970). By contrast, few of these deficits are seen in individuals with agenesis of the corpus callosum when there are tested in certain tasks requiring intermanual comparisons. For example, whilst callosotomized patients are unable to cross-match objects held in both hands out of view, acallosal subjects have no difficulties in performing this task although their response times may be longer than in callosally-intact subjects (Ettlinger et al., 1972, 1974; Saul and Gott, 1973; Jeeves, 1979; Sauerwein et al., 1981). The same is true when callosotomy is performed before puberty (Lassonde et al., 1986, 1991).
