“…As of yet, the pattern of consistent cognitive deficits in ACC has not been fully described. However, our results thus far, and those appearing in the research literature, suggest that high-functioning adults with ACC typically have moderate but detectable deficits in the following areas: interhemispheric transfer of complex sensory information and learning [15][16][17][18][19][20]; bimanual motor coordination [18,21,22]; complex novel problem-solving [13,14,[23][24][25][26]; processing of subtle phonetic and semantic aspects of language [13,[27][28][29][30][31][32]; comprehension of second-order meanings of language [33][34][35]; and psychosocial understanding and behavior [14,35]. Since the individuals with ACC that we have studied have complete ACC, normal IQs, and few, if any, other structural brain abnormalities, we refer to this form of ACC as Primary ACC.…”

Archival data from a survey of parent observations was used to determine the prevalence of social and behavioral problems in children with agenesis of the corpus callosum (ACC). Parent observations were surveyed using the Child Behavior Checklist (CBCL) for 61 children with ACC who were selected from the archive based on criteria of motor development suggesting a relatively high general level of functioning. Younger children with ACC (ages 2-5) were rated as primarily having problems with sleep. Older children with ACC (ages 6-11) manifested problems in attention, social function, thought, and somatic complaints. The older children with ACC were also compared to CBCL data from 52 children with autism who were selected from a previous study. Children with ACC were generally less impaired than children with autism on nearly all scales, with significantly less severe problems in the areas of attention, anxiety/depression, social function, and unusual thoughts. A further questionnaire related to diagnostic criteria for autism indicated that some children with ACC had traits that are among those that contribute to the diagnosis of autism within the domains of social interaction and social communication, but fewer who manifest repetitive and restricted behaviors.

“…Several decades ago, seminal work on split brain subjects already indicated that the anterior CC is critical for bimanual performance (Preilowski 1972;Jeeves et al 1988). The role of the CC in bimanual learning has received much less attention.…”

“…We partitioned the CC into seven subregions based on its connections to the (1) prefrontal regions, (2) premotor and supplementary motor areas, (3) primary motor cortex, (4) primary sensory cortex, and (5) occipital, (6) parietal, and (7) temporal cortex, as we have done previously Gooijers et al 2011). We investigated the organization of the seven CC subregions in healthy young adults in relation to performance on a bimanual visuomotor task, which is a computerized version of the "Etch-a-sketch" device (for earlier versions, see Preilowski 1972;Jeeves et al 1988;Mueller et al 2009). The novelty of the present task is that we systematically manipulated the following parameters collectively: hand dominance allocation, frequency ratio (FR), and whether the FR was an integer or noninteger ratio, an element that is critical in the timing of fingertapping movements (Summers et al 1993).…”

The corpus callosum (CC) is the largest white matter tract in the brain. It enables interhemispheric communication, particularly with respect to bimanual coordination. Here, we use diffusion tensor imaging (DTI) in healthy humans to determine the extent to which structural organization of subregions within the CC would predict how well subjects learn a novel bimanual task. A single DTI scan was taken prior to training. Participants then practiced a bimanual visuomotor task over the course of 2 wk, consisting of multiple coordination patterns. Findings revealed that the predictive power of fractional anisotropy (FA) was a function of CC subregion and practice. That is, FA of the anterior CC, which projects to the prefrontal cortex, predicted bimanual learning rather than the middle CC regions, which connect primary motor cortex. This correlation was specific in that FA correlated significantly with performance of the most difficult frequency ratios tested and not the innately preferred, isochronous frequency ratio. Moreover, the effect was only evident after training and not at initiation of practice. This is the first DTI study in healthy adults which demonstrates that white matter organization of the interhemispheric connections between the prefrontal structures is strongly correlated with motor learning capability.

“…Young children, in fact, often react as though functionally acallosal (e.g., Gazzaniga, 1974;Jeeves, Silver, & Milne, 1988;Joseph, Gallagher, Holloway, & Kahn, 1984;Njiokiktjien, Driessen, & Habraken, 1986). One measure of this condition is crossed finger localization in which a finger (or fingers) is briefly touched by the examiner and the subject is required to identify the stimulated finger(s) by pointing with the thumb of the other hand.…”
