Neuroanatomical Asymmetry, Handedness, And Family History Of Handedness: A Study Of The Markers Of Structural And Functional Lateralization, Steven A. Lifson
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
This study investigated the associations between (1) handedness (demonstrated preference of one hand for the performance of most unimanual tasks) and neuroanatomical asymmetry (measurable differences in width between the cerebral hemispheres) and (2) familial history of handedness (the presence of a left-handed sibling or parent of a right-handed subject) as an intervening factor in the relation between handedness and neuroanatomical asymmetry. Width measurements of the brain were derived from computerized tomographic (CT) films and grouped in to categories by hand preference (measured by the Edinburgh Handedness Inventory) and family history. The measurements of right (n=68), right with left-handed relatives (n=24), …
