REVIEW Cerebellar tDCS: How to Do It

# The Author(s) 2014. This article is published with open access at Springerlink.com Abstract Cerebellar transcranial direct current stimulation (cerebellar tDCS) is a non-invasive technique for inducing prolonged functional changes in the human cerebellum. Avail-able data show that this simple and safe technique can mod-ulate several motor and non-motor cerebellar functions in healthy humans. Also, preliminary data suggest that cerebellar tDCS is a possible therapeutic option in patients with cerebel-lar disorders. To provide a reference for those approaching this technique for the first time in healthy humans and patients, we here briefly and practically review the methodology for cere-bellar tDCS, discussing electrode types, positions, DC dura-tion and intensity. Recent modelling studies confirm that the electric field generated with the methodology reviewed here reaches the cerebellum at a strength within the range of values for modulating activity in the cerebellar neurons experimen-tally assessed
