The functional characterization of callosal connections
2022, Progress in NeurobiologyCitation Excerpt :Surprisingly, patients with anterior callosotomy do not suffer of any deficit and do not show the symptoms typical of patients with complete commissurotomy (reviewed in Berlucchi, 2012) or with lesion of prefrontal areas. Patients with sections of the trunk of the CC show impaired inter-manual transfer of sensorimotor habits, a certain degree of inter-manual conflict (Wilson et al., 1977; Bogen, 1979), as well as an inability to perform complex bimanual tasks requiring independent sequencing of hand movements (Preilowski, 1975; Zaidel and Sperry, 1977). The learning of new motor skills and their interhemispheric transfer depends on a distributed transcallosal network including dorsal premotor, motor, cingulate motor, somatosensory, and posterior parietal areas, as shown by an EEG study (Andres and Gerloff, 1999).

2014, Behavioural Brain ResearchCitation Excerpt :Liepmann himself was cautious enough to point out that the right hemisphere may also possess some praxis skills, especially for the left half of the body [1]. Since then, the possibility that the right hemisphere may contain some capacity to control skilled purposeful movements in right handers has also been postulated by several authors, as a possible explanation for the sparing of certain left-hand praxis functions in patients with LHD or with surgically or naturally occurring callosal lesions [5,7–10,65]. Patients with ideomotor apraxia (IMA) may commit errors when performing transitive and intransitive gestures.
Interactions between brain structure and behavior: The corpus callosum and bimanual coordination
2014, Neuroscience and Biobehavioral ReviewsCitation Excerpt :Based on the fact that the CC is the major communication link between the left and right hemisphere, one would expect split-brain patients, whose CC connections are sectioned partly or entirely, to show serious deficits in bimanual performance. Apparently, the presence of such deficits is generally dependent on the ‘nature’ of the bimanual task studied (Caille et al., 2005; Eliassen et al., 1999, 2000; Franz et al., 1996, 2000; Jeeves et al., 1988; Kennerley et al., 2002; Preilowski, 1972; Sternad et al., 2007; Zaidel and Sperry, 1977). Indeed, evidence has been advanced that familiar bimanual actions, such as opening a jar or tying shoelaces, remain intact in callosotomy patients, whereas novel actions, such as learning to play golf, are impaired (Franz et al., 2000).
