A study of 473 adults has found that people who are overweight have less white matter, which
connects different brain areas and enables signaling between them.

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).

brain, ultimately creating a map of 383
different brain areas,
connected by 6,602 individual links.

connect different parts of the
brain — did not differ, nor did the overall surface
area of the
brain cortex.
Neuroscientists have taken this a step further by assuming that
different areas in the
brain are
connected if they show synchronized variations while the
brain is in a resting state.
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.
When compared to the control group, type 2 patients showed decreased integrity in the white matter of two
different areas in the
brain — the cingulum bundle, which is a fiber tract that
connects regions in the default - mode network, and the uncinate fasciculus, which
connects regions important for executive function and memory.
New York, NY (February 1, 2012)-- For decades, researchers have debated whether Alzheimer's disease starts independently in vulnerable
brain regions at
different times, or if it begins in one region and then spreads to neuroanatomically
connected areas.
White matter acts like the
brain's subway system; it
connects different areas of gray matter to each other, helping messages travel quickly.
