Transcranial Direct Current Stimulation (tDCS): A form of neurostimulation that uses constant, low direct current delivered via electrodes on the head.
Electroconvulsive Therapy (ECT):A procedure, done under general anesthesia, in which small electric currents are passed through the brain, intentionally triggering a brief seizure and causing changes in brain chemistry that can quickly reverse symptoms of certain mental health conditions.
Neurofeedback: A type of biofeedback that uses real-time displays of brain activity—most commonly electroencephalography (EEG)—to teach self-regulation of brain function.
