Transcranial Alternating Current Stimulation (tACS) is a neuromodulation technique that uses gentle oscillating electrical currents to interact with the brain's natural rhythmic activity. Unlike tDCS, which primarily influences neuronal excitability, tACS is designed to target specific brainwave frequencies and encourage synchronization of neural networks associated with cognitive and emotional functioning.

Because different brainwave patterns are associated with processes such as attention, memory, sleep, learning, and emotional regulation, tACS can be tailored to address specific functional goals. This personalized approach may help improve focus, information processing, mental performance, and overall brain efficiency. tACS is a non-invasive and comfortable intervention that can be integrated into comprehensive brain optimization and wellness programs.
