title: Computed tomographic localization of the precentral gyrus.
abstract: The superior frontal, precentral, and central sulci of fixed brain specimens were marked and then scanned by computed tomography. A constant relationship between the posterior ends of the superior frontal and precentral sulci facilitated accurate identification of the anterior border of the precentral gyrus in both unmarked fixed brains and patients. Precise localization of this gyrus can aid in localization of lesions and correlation with functional changes.
