Abstract
1
We recently described the chemical network properties of the human brain using in vivo proton magnetic resonance spectroscopy ( H
MRS). In a separate study of aging we found increased concentration of chemicals in the prefrontal and sensorimotor cortices up to the
third decade of life, and subsequent decrease of chemical concentrations in the same brain regions after the third decade between young
and middle age. We anticipated that these age-dependent differences in chemical concentrations might be a reflection of the chemical
network reorganization of the brain during aging. The pattern of chemical connectivity within and across brain regions for all regional
