Transcranial Direct Current Stimulation in Psychiatry

Transcranial Direct Current Stimulation is a safe Non-invasive brain stimulation technique studied in various psychiatric disorders.(3) It involves the application of low-intensity electric current using electrodes placed over the head to modulate cortical activity. It alters the neuronal resting membrane potential causing depolarization or hyperpolarization, resulting in an increase or decrease in cortical excitability. Anodal and cathodal tDCS are often used to increase and decrease excitability. It can target different areas of the brain including cognitive and motor networks.
