tdcs device

tDCS is the practice of passing mA currents through one’s brain in order to enhance or retard neural excitability between the electrodes placed on the skull (read the link for better grokking of the concept; I’m at lunch and time is short).  It is used in research primarily to understand if it is any use at all in Parkinson’s disease, tinnitus, amblyopia, fibromyalgia, and post-stroke motor deficits.

The gizmo above is the constant-current  supply circuit rendered by my colleague Noel, with 0.5, 1.0, 1.5 and 2.0 mA selectable switches.  I think it beautifully done; only the 12V battery and the electrodes are not shown.  There is testing to be done, but it is heartening to see it looking so nice
