Corticospinal Plasticity in Bilateral Primary Motor Cortices Induced by Paired Associative Stimulation to the Dominant Hemisphere Does Not Differ between Young and Older Adults

Figure 3

Normalized MEP changes following PAS. The amplitude of MEPs following PAS was not affected by age. The percentage of MEP change post-PAS relative to baseline did not differ significantly between the stimulated and unstimulated hemispheres nor between the attend left and attend right conditions.
