The current proposal seeks quantify neural inhibition using magnetic resonance spectroscopy (MRS) and transcranial magenetic stimulation (TMS) in older Veterans to identify how each measures contributes to aging-related changes in motor performance. Currently, over 56% (11.8 million) of Veterans are over age 60. Recent research has shown that aging is associated with decreased cortical inhibition and impaired hand motor function. However, this loss of inhibition is not an inescapable consequence...
