Neurostimulation

technique of brain electric stimulation therapy which uses low current delivered via electrodesm placed on the scalp

Neurostimulation is the purposeful modulation of the nervous system's activity using invasive (e.g., microelectrodes) or non-invasive means (e.g., transcranial magnetic stimulation, transcranial electric stimulation such as tDCS or tACS). Neurostimulation usually refers to the electromagnetic approaches to neuromodulation.
