This article investigated relationship between corpus callosum shape and cognitive functions. In this study, 102 participants were used, and their corpus callosum images were obtained by 3.0-T GE scanner and T1-weighted three-dimensional 3DSPGR sequence. Furthermore, 21 specific cognitive measures with seven composite scores were examined to see the correlation. Overall, this study found that thinner and more curved shaped corpus callosum resulted in slower attention processes and verbal speed. This finding may be related to psychological disorders such as attention-deficit hyperactivity disorder (ADHD), where abnormal courpus callosum are often found in the patients.
