Morphological changes in aging brain structures are differentially affected by time-linked environmental influences despite strong genetic stability.

Neurobiology of aging - 1 Feb 2004

Pfefferbaum Adolf, Sullivan Edith V, Carmelli Dorit

Abstract excerpt

This longitudinal study used the full twin model to estimate change and stability of genetic contributions to morphology of two brain structures, the corpus callosum and lateral ventricles. The 142 subjects were 34 monozygotic (MZ) and 37 dizygotic (DZ) elderly male twin pairs from the National Heart, Lung, and Blood Institute (NHLBI) Twin Study who underwent brain magnetic resonance imaging twice, separated by a...
