Electrode$Care!–!It is advised that you replace your electrode sponge inserts every 3-4 uses, and replace your
sponge electrode shells every 2 months.
It is important to properly maintain sponge electrode shells and electrode sponge inserts in order to obtain
consistent and uniform current distribution throughout the tDCS electrode. Reusing the sponge inserts past the
recommended number of uses results in inconsistencies in current density distributions.
Saline application - An application of ~7 ml of 0.9% saline to the 2x2 electrode sponge insert or ~15 ml of 0.9%
saline to the 3x3 electrode sponge insert is recommended for optimal stimulation configuration. Saline
application should be performed after dry electrode sponge has been inserted into electrode holder.
