Current limits

Despite not being fully understood, TDCS is widely considered safe for short experimental use (Utz et al. (2010)). Work by Bikson et al. (2009) to establish rough bounds on the safe currents and exposure times for TDCS failed to produce damage to mouse brains with less than 142.9A, about 700,000 times the current used in most human trials. Further, the damage (brain lesions) scaled linearly with charge density, which is consistent with a simple burning e ect (i.e. an e ect unlikely to occur at lower amperage).
