Neuroelectrics Sponstim

The Sponstims are a family of sponge-based electrodes suitable for any type of transcranial electrical stimulation with Starstim® and Starstim®-Home, including tDCS, tACS and tRNS waveforms. The Sponstim electrodes offer a range of different shapes and sizes to suit various experiment requirements. The circular model with 25 cm² and the rectangular model with 35 cm² provide a large, comfortable and reliable contact, which is ideal for bipolar (anodal or cathodal) experiments. The smaller Sponstim models, one with a circular area of 8 cm² and one with pellet area of π cm², are the solutions designed for multi-electrode tES. All models must be used with saline solution.
