tACS : Alternating Current Stimulation
Learn about transcranial Alternating Current Stimulation (tACS) here.
What is tACS?
tACS is a type of non-invasive brain stimulation.
With tACS, the electrical current increases and decreases like a wave function. Compare this to tDCS which has a contsant current level.
tACS researchers use specific frequencies of tACS stimulation to influence known brainwaves e.g. Alpha waves, Gamma waves
