Can You Use Electricity to Supercharge Your Brain?

Transcranial Direct Current Stimulation (TDCS) is a technique using electric currents to stimulate the brain, claimed to enhance memory, focus, and treat conditions like depression. However, its effectiveness is debated, with studies showing mixed results. TDCS involves electrodes placed on the scalp, delivering a mild current, and is less intense than electroconvulsive therapy. While some research suggests potential benefits for mood disorders and stroke recovery, inconsistencies in study methodologies and the unknown physiological effects pose challenges. Caution is advised for home use until more is understood.
