Perception is biased by amplitude and phase dynamics of ongoing alpha oscillations, while effects of alpha oscillations in somatosensation are less well understood.

tACS was tuned to individual somatosensory alpha oscillations (mu-tACS) and applied during a somatosensory perception task.

Mu-tACS modulates somatosensory perception phasically, but not tonically.
- class="label">•
tACS tuned to visual alpha oscillations (alpha-tACS) does not modulate somatosensory perception.

Our results support the validity of the pulsed inhibition framework in somatosensation.
