Consistency of right-hand preference correlates with callosal isthmus size. Anterior corpus callosum (CC) regions vary as a function of sex and right- versus left-hand preference. We analyzed regional CC anatomy in a sample of right- and left-handed men and women on the basis of both degree ("Consistency") and direction ("Hand") of hand preference scores. Significant Hand x Consistency effects indicated that both are important factors in CC organization. These data also suggested that a single continuum of hand preference and regional CC size may not be applicable across all subjects.
右手偏好的一致性与胼胝体峡部大小相关。胼胝体前部区域因性别以及右手与左手偏好的不同而有所变化。我们根据手偏好分数的程度(“一致性”)和方向(“手”),分析了一组右利手和左利手男性及女性的胼胝体区域解剖结构。显著的“手×一致性”效应表明,二者都是胼胝体结构中的重要因素。这些数据还表明,单一的手偏好连续体和区域胼胝体大小可能并不适用于所有受试者。
