Midsagittal magnetic resonance images of the corpus callosum and lateral ventricle in (A) a healthy younger adult (aged 30 years); and (B) a healthy older adult (aged 68 years). Note the structural changes with age as the lateral ventricle becomes much larger and the corpus callosum becomes much thinner. However, the length of the corpus callosum remains approximately constant.
