Transcranial direct current stimulation (tDCS) is a non-invasive brain stimulation technique that involves applying a low electrical current to specific areas of the brain using electrodes placed on the scalp. This technique is used to modulate neural activity and has been studied for its potential therapeutic effects in a variety of neurological and psychiatric disorders. tDCS has been shown to enhance learning and memory, improve motor function, and alleviate symptoms of depression, among other potential benefits. The precise mechanisms by which tDCS exerts its effects are not fully understood, but it is thought to alter neuronal excitability and synaptic plasticity.
