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

Other Stimulation Modes:

Direct Current Stimulation

Random Noise Stimulation

Pulsed Current Stimulation

Rippled Current Stimulation
