[Note (updated 8/9/15): Alex is using a research version of the mindGear device. The device as available to the general public does not include a tDCS program.]
The folks at the Neural Engineering Group (associated with Marom Bikson’s NY City College Neural Engineering Lab) are producing a series on tDCS. Here is their first episode!
My Notes: Could you force an action potential with tDCS? (TMS does)
Visual memory improved by non-invasive brain stimulation (paywall)
Richard P. Chi, Felipe Fregni, Allan W. Snyder
Dosage: mA x time, i.e. 30 mA minutes could be 1.5mA for 20 minutes.
Memory improvement montage: Anode between T8 & FT8, Cathode between T7 & FT7
