for 1mA 35cm2 50uA/cm2 i use 30 min (L-DLPFC and right orbital) for 2mA 9cm2 in higher current density work much faster efect is precivable after few second

for 1mA 35cm2 50uA/cm2 i use 30 min (L-DLPFC and right orbital) for 2mA 9cm2 in higher current density work much faster efect is precivable after few second (aplication 3min) bud ther is a problem - skin iritation and is little itchi (early expediments) in publication is recomandet current density under 60uA/cm there was much more but still under tishue damge limit ATA from BRMLAB
