Figure 4. Changes in Cortical Excitability.

Figure 4

Changes in cortical excitability were indexed using motor-evoked potentials (MEPs). Here MEP amplitudes are averaged and presented across all conditions, prior to stimulation (PRE), in-between stimulations (INTER) and immediately after stimulation (POST). (*Denotes significance. *(blue) infers significance PRE vs INTER, *(purple) INTER vs POST.
