Originally developed for the Martian Republic by Trivol Enterprises, Neuro Feedback Devices were intended for use during interrogations. These small, handheld devices could be carried by field officers and put to use in the field by officers with minimal training. Electrodes on these devices were configured for use on various neurological trigger point using autosensing technology. Despite the production of several hundred of these devices no such device was ever officially used by the Martian Republic or any recognized military unit.
