Phase-specific aftereffects of transcranial alternating current stimulation on visual processing

Phase-specific aftereffects of transcranial alternating current stimulation on visual processing
Oscillatory neural activity has been assigned a functional role in various cognitive processes and neuropathologies. The direct modulation of brain oscillations by transcranial alternating current stimulation (tACS) offers the unique opportunity to probe their causal relevance for cognition. Critically, the assumption of phase-specific modulation of neural activity by tACS is an important prerequisite but still open to debate. Here, we investigated the phase-specificity of immediate tACS aftereffects on stimulus-driven oscillatory responses, namely steady state visual evoked potentials (SSVEP). ... read more
