2014-10-20 (M) tDCS Unit

The manual steps were numbered 1-66.

Some research was done into HDtDCS where the primary difference seems to be electrodes encircle a central electrode placed over the area of interest on the scalp. This is supposed to reduce the negative effects of treatment such as reduced ability in other brain functions due to proximity to the cathode electrode. More searching was done to make a custom shape electrode which completely encircles a small electrode. A material was found which is absorbent and does not require stitching at the edges. It was a car shammy made from a gamy material. Its absorbency makes it a top candidate for electrode material. The shammy became rigid when dry but is pliable when wet.

Car shammy held out to show rigidity
