Furthermore, brain imaging data for these very elderly animals shows a slight loss of grey matter (neuronal cell bodies), an effect that the researchers have not yet explained, as well as significantly slowed atrophy of white matter (the neuronal fibers
connecting different areas of the brain).
White matter fibers
connect the different areas of the brain and abnormalities in white matter may be tied to the development of dementia and other cognitive disorders.
