Treating pain with transcranial alternating current stimulation (tACS)


  • Transcranial alternating current stimulation (tACS) did not modulate tonic experimental pain or autonomic responses in healthy subjects.

Why this matters ?

  • tACS is an emerging non-invasive, safe, cost-efficient and potentially mobile neuromodulation technique that involves modulating neural oscillations in the brain by a weak alternating, sinusoidal current applied to the scalp.

  • The research on tACS is currently lacking, with only two studies conducted to date and showing that this treatment at alpha frequencies over somatosensory areas has the potential to produce analgesia.
