The MRI Sponstim is a family of sponge-based radio translucent electrodes suitable for any type of transcranial electrical stimulation with Starstim® during magnetic resonance imaging (MRI). The MRI 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 MRI Sponstim models, one with a circular area of 8 cm² and one with a pellet area of π cm², are the solutions designed for multi-electrode tES. All models must be used with saline solution.
Chosen sizes of MRI Sponstim are included with Starstim® MRI extension kits.
