Promoting Motor Cortical Plasticity with Acute Aerobic Exercise: A Role for Cerebellar Circuits

Figure 4

MEP recruitment curve data before and after PAS under rest (a and c) and aerobic exercise conditions (b and d) for each participant in both the PAS₂₅ (a and b) and PAS₂₁ (c and d) groups. Unfilled circles and filled squares depict MEP amplitude at each stimulator intensity for each participant at pre- and post-PAS time points, respectively. Likewise, dashed and solid lines depict linear regression lines showing average recruitment curve slope for the group at pre- and post-PAS time points, respectively. MEP: motor evoked potential; M_max: maximal motor-wave; PAS₂₅: paired associative stimulation with 25 ms interstimulus interval; PAS₂₁: paired associative stimulation with 21 ms interstimulus interval; TMS: transcranial magnetic stimulation; RMT: resting motor threshold.
