Transcranial Direct Current Stimulation (tDCS) is a form of non-invase neurostimulation that delivers a constant low level current to the brain through the use of electrodes placed on the scalp. This neuromodulation technique uses a steady current between 1 - 2 mA delivered through electrodes to targeted regions of the brain to modulate brain function. Using different electrode configurations, tDCS can be used to either excite or inhibit neuronal activity in the targeted region.
Headquartered in New York City, Caputron is the leading worldwide distributor of home, clinical and research neurostimulation technology, such as tDCS, TMS, CES and EEG. By partnering with world-class device manufacturers, we supply a range of excellent neurostimulation devices and accessories, such as Transcranial Magnetic Stimulation (TMS), Cranial Electrotherapy Stimulation (CES) and Transcranial Direct Current Stimulation (tDCS).
These affordable sponge inserts are the same ones used in research labs and clinics. They come dry and expand when wet. A pack contains 10 high quality replacement sponges.
These Sponge inserts by Caputron are used as replacement sponges and come in different sizes. The 2"x2" and 3"x3" square sponge inserts fit into their respective size electrodes from Caputron, Amrex, Apex and Mettler. The 1.5" round sponge inserts fit both the BrainDriver and Fisher Wallace electrodes.
Pack comes with 10 sponge inserts.
It is important to properly maintain electrode sponge inserts in order to obtain consistent and uniform current distribution throughout the tDCS electrode, this minimizes the chance of current “hotspots” where current may tend to concentrate at certain areas of the electrode sponge surface due to the constant wear and subsequent degradation of the sponge material through usage—this results in inconsistencies in current density distributions. As a result, it is advised that you replace your electrode sponge inserts every 3-4 uses.
These sponges come dry. As soon as one applies saline solution to them, they immediately absorb the solution and expand. They work best when inserted into the rubber electrode pad first as they expand quickly when wet. They provide excellent contact with and conductivity to the application area.
Saline application - An application of ~7 ml of 0.9% saline to the 2x2 electrode sponge insert, ~15 ml of 0.9% saline to the 3x3 electrode sponge insert, or ~3 mL of 0.9% saline to the 1.5" electrode sponge insert is recommended for optimal stimulation configuration. Saline application should be performed after dry electrode sponge has been inserted into electrode holder.

Everything was fine.
This is amazing. I did it
Activadose II tDCS kit
The replacement sponges for the electrodes worked just fine. Purchase and fulfillment went just fine also.
