TPCS

Transcranial pulsed current stimulation (tPCS) is a non-invasive brain stimulation technique that modulates neuronal activity by delivering oscillatory current to the cortex via surface electrodes placed on the auricular structures (Datta et al., 2013). This method shows promising features as a neuromodulatory tool, as it is simple, painless, easy to use, portable and safe (Castillo Saavedra et al., 2014, Fitzgerald, 2014, Morales-Quezada et al., 2014); however little is known regarding its mechanisms of modifying behaviors.
