Transcranial Alternating Current Stimulation (tACS)
Similar to the nature in which electrical signals from the brain are obtained by EEG, signals can be delivered to the brain. Through the delivery of low-level electrical current waveforms, interactions with the underlying neurons are possible. This is a minimally invasive, patient specific treatment that can be used by both individuals with neuronal disorders, as well as those looking to optimize brain function.
The BrainTrain digital therapeutics system integrates many technologies including tACS, and EEG. With treatments like tACS drug-free interventions of Alzheimer's, attention-deficit/hyperactivity disorder, stroke rehabilitation, and mental state selection are possible. The BrainTrain device operates with a unique closed-loop EEG+tACS feedback system allowing this level of superior functionality.
