Investigational drug(s) / intervention(s)

Theta Burst Stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation)

Theta Burst Stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation): Participants will receive a single session of either iTBS or cTBS (600 pulses) targeting the right cerebellar Crus I/II. One week after the initial TBS, they will receive another single session of iTBS or cTBS (600 pulses) at the same site.

Study summary

This study aims to establish a personalized theta burst stimulation (TBS, an advanced variant of repetitive transcranial magnetic stimulation, rTMS) protocol considering autistic idiosyncrasy (interindividual variability).

Primary outcome measure(s)

  • Functional MRI (default mode network) - BOLD Signal — Baseline, Week 1, Week 2
    Blood-oxygen-level-dependent (BOLD) signal is a measurement used in fMRI, which reflects the neural activity.
  • MEP amplitude — Baseline
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 1 (5 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 2 (5 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 1 (10 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 2 (10 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 1 (15 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 2 (15 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 1 (20 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
  • MEP amplitude — Week 2 (20 minutes post-TBS)
    MEP (motor evoked potential) amplitude is a measure of corticospinal excitability.
