Consistent neuromodulation
Even slight differences in cortical source location and orientation across subjects results in drastically different scalp anodal (red) and cathodal (blue) electrode positions¹. GTEN calculates individualized stimulation montages for consistent targeting between subjects.

High fidelity head models
High fidelity head models
The reciprocity theorem states that a source’s scalp voltage projection and the stimulation pattern required to modulate that source are the same. Therefore, the accuracy of both source localization and neuromodulation depend on the head model used. Our high fidelity head models thus ensure both the most accurate source localization and neuromodulation results possible.
