Non-invasive cerebellar stimulation
Non-invasive cerebellar stimulation (NICS) is the application of non-invasive neurostimulation techniques on the cerebellum to modify its electrical activity. Techniques such as transcranial magnetic stimulation (TMS) or transcranial direct current stimulation (tDCS) can be used.
