Midsagittal Morphometry of the Corpus Callosum in Native Tibetan Adults: Distinctive Preservation of the Splenium and Anterior Sexual Dimorphism

Native Tibetan adults display a unique CC profile with localized anterior sexual dimorphism and age-associated posterior preservation. These findings likely reflect neuroplastic adaptations to lifelong hypobaric hypoxia and provide essential population-specific reference values to prevent misinterpretation of adaptive morphology as pathology in neurosurgical and craniofacial practice at high altitude.
