Tonic and kinetic motor units revisited: does motor unit firing behavior differentiate motor units?
Motor unit firing behavior in a muscle may be fitted for its function.
T2' values differed significantly between MS patients and healthy subjects. The reduced T2' values in the basal ganglia are presumably related to higher iron concentration whereas the increased T2' in frontal NAWM most probably reflects reduced tissue metabolism. T2' imaging is feasible for routine-use and promising for monitoring therapy effects.
