The Soterix Medical HD-tDCS system delivers non-invasive, precision neuromodulation by replacing conventional diffuse sponge pads with compact, high-definition electrodes arranged in the industry-standard 4x1 ring montage. Engineered to deliver targeted, focal stimulation to specific cortical regions, it pairs anatomical accuracy with comprehensive subject comfort controls, automated double-blinding, and full multimodal neuroimaging compatibility.

Key Features

4x1 Focal Optimization: Specifically designed for the validated 4x1 ring montage (one central electrode surrounded by four return electrodes), restricting current flow to targeted cortical structures without diffuse peripheral spread.
SMARTscan™ Impedance Monitoring: Continuous, real-time visual "traffic light" indicators provide instant feedback on electrode contact quality prior to, during, and after stimulation runs.
Auto-Sham Double Blinding: An intelligent, single-switch sham feature automatically replicates the active ramp-up and ramp-down profiles to maintain rigorous study blinding without operator bias.
Pre-Stimulation Tickle Mode: Delivers a low-intensity conditioning current prior to protocol execution, habituating naive subjects to skin sensations and minimizing dropout rates.
On-the-Fly Relax Slider: Allows operators to transiently dial down current intensity if a subject reports discomfort, resuming target stimulation levels without terminating or invalidating the trial session.
Multimodal Compatibility: Fully compatible with concurrent EEG, fMRI (with artifact management), MEG, PET, fNIRS, and eye-tracking setups.
Scalable MxN Architecture: Built for modular growth, supporting upgrades and daisy-chaining into multi-channel MxN arrays as research needs evolve.
Neurotargeting™ Integration: Direct native workflow compatibility with Soterix Neurotargeting and HD-Explore modeling software for finite element method (FEM) current flow simulation and dose design.
