Direct Cortical Measurement of the Intensity and Pattern of Current Flow Produced by TDCS

NCT02263274 · Status: COMPLETED · Phase: NA · Type: INTERVENTIONAL · Enrollment: 30

No results posted yet for this study

Summary

The primary study objective is to measure the electrical fields evoked by tDCS using subjects who have implanted intracranial electrodes as part of their evaluation for epilepsy surgery. The measurements obtained in these subjects and their brain MRI will be employed to validate existing mathematical models.

In the future, these refined models can be used to target tDCS to predetermined brain regions in healthy and subjects and patient populations. As described above in the safety section, the intensities of stimulation applied in this project are not expected to produce changes in brain function, are below intensities commonly applied in clinical trials, and fall well below safety limits suggested by animal studies.
