Click detectability depends on which half of a 4-Hz stimulation cycle it falls in

Evidence

Experiment 1 revealed that click detection under 4-Hz tACS is modulated by tACS phase: performance was significantly better during one half of the 4-Hz tACS cycle than during the opposite half. Performance without tACS was intermediate, but did not differ significantly. The tACS phase effect was strongest in the vicinity of the tACS frequency but not strictly frequency-specific as it extended to higher frequencies. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4768
