Introduction Transcranial direct current stimulation (tDCS) is a non-invasive neuromodulation technique that delivers low-intensity direct current (typically 0.5 to 2 mA) to the cerebral cortex via surface electrodes placed on the scalp. It modulates cortical excitability by altering resting membrane potentials without directly inducing neuronal action potentials. Depending on polarity: These effects are subthreshold, but…
