Clinical Trial Summary

Investigating modulation of motor cortex excitability by transcranial magnetic stimulation and transcranial direct current stimulation.


Clinical Trial Description

Purpose of this pilot study is to modulate the motor cortex excitability by transcranial magnetic stimulation and transcranial direct current stimulation. Electromyography will be recorded on right abductor digiti minimi muscle to find the motor threshold and measure motor evoked potentials for each healthy participant. In addition, electroencephalography (EEG) data will be collected on the scalp with a high-density EEG net. Eighteen healthy participants will be in this study. Each participant will be seated in a reclining chair and applied non-invasive magnetic and electrical stimulations on the scalp. At baseline, the participant's resting motor threshold (RMT) will be estimated by adjusting the intensity of TMS applied on the left motor cortex to achieve motor-evoked potentials of about 50 uV with 10 TMS pulses at a rate of 0.25 Hz. Then a 3-condition, 3-session, 6-sequence randomized crossover experiment will be used to characterize and compare three versions of tDCS stimulation: anode, cathode, sham. Before and after a 10-min tDCS condition is applied, TMS pulses at 120% of RMT intensity will be applied for 10 minutes and TMS-evoked potential and motor-evoked potential amplitudes will be measured. Each session has at least 1-day gap to remove outlasting effects. We will also be collecting structural magnetic resonance imaging (sMRI) to target primary motor cortex precisely. ;
