HD-Explore software

The most advanced and intuitive software to simulate brain current flow during tDCS, tES, HD-tDCS and HD-tES.

HD-Explore™ was the first commercial software for precision modeling of brain current flow during transcranial electrical stimulation. And over 5 years HD-Explore™ has continued to introduce state-of-the-art features in support of optimized tDCS, tES, HD-tDCS and HD-tES.

HD-Explore™ is protected by patents, other intellectual property rights, patents pending or other intellectual property rights pending.


Easy to use software without compromising accuracy

HD-Explore™ is the only stand-alone modeling software that provides predictions of brain current flow with equivalent accuracy to the most advanced engineering software. The reason is a breakthrough in how models are solved based on the principles of linearity and super-position. The result is that Soterix Medical HD-Explore™ is able to provide performance comparable to a team of engineers working with a super-computer for days, using a laptop in just minutes.

HD-Explore™ is the only research grade software used in hundreds of research publications including:

The same breakthrough that allows instant current flow solutions making HD-Explore™, the only software that can do simulation for any tDCS, tES, HD-tDCS and HD-tES montage.

Neurotargeted Montage:

Using Soterix Medical’s exclusive Neurotargeting software, HD-Explore, research optimized High-Definition tDCS to target the angular gurus. High-Definition tDCS, an exclusive Soterix Medical Technology, uses HD electrode arrays to maximize brain targeting. Here, researchers at the University of Pennsylvania were able to designed a 4x1 montage that maximizes targeting. HD-Explore is simple to use and runs on a conventional laptop, yet the results are compatible to state-of-the-art computational lab approaches.

Rigorous Science:

Published in the Journal of Neuroscience, the University of Pennsylvania teams discover a causal role of the left angular gyrus in lexical-semantic integration which provides motivation for novel therapeutic applications in patients with lexical-semantic deficits. This discovery is only possible using focal HD-tDCS which is the only target and sub-threshold neuromodulation approach. Only though targeted and specific neuromodulation could the the angular gyrus have been isolated. Conventional tDCS lacks the focality needed for angular gyrus stimulation and TMS will lead to supra-threshold secondly activation.

Real Impact:

Several news agencies highlight both the scientific and clinical impact of this work including Science Daily and John Hopkins News. The combination of scientific innovation and state-of-the-art technology (Soterix Medical HD-Explore and HD-tDCS) make this work foundational. Because a brain region was directly implicated using targeted sub-threshold neuromodulation, the work establishes a foundation for ongoing exploration of brain function and treatment options.
