Brain Stimulation

Current technologies claim to alter neural activity with the use of magnetic or electrical stimulation externally applied to the head. We are interested in understanding the impact of these low levels of electrical stimulation (e.g. tDCS) in terms of the nature and reliability of the effects induced.
