Pilot Study of Neurofeedback for Photosensitivity in Mild Traumatic Brain Injury
Sponsor: VA Office of Research and Development
Summary
The goal of this study is to complete a pilot study testing the feasibility and acceptability of low-intensity pulse-based transcranial stimulation (LIP-tES) neurofeedback intervention for reducing photosensitivity symptoms in Veterans with a history of mild traumatic brain injury (mTBI). The study will also complete resting-state MRI scans to assess neurophysiological markers of photosensitivity and changes associated with LIP-tES intervention.

Micro Current Neurofeedback Device using Low-Frequency Pulse-Based Transcranial Electrical Stimulation
The EEG interface device is a J\&J Engineering 1-330 C2 box. The software used to determine LIP-tES feedback patterns was developed by Neurogen High Performance Neurofeedback. The EEG sampling frequency is 256 Hz on each of 2 EEG acquisition channels. The feedback LIP-tES is delivered via the 4 EEG leads (A+,A-,B+,B-), with respect to the Common Neck Reference. During each session, 2 electrodes (A- and B-) are attached to the participant's left and right mastoids, while the remaining two electrodes (A+ and B+) are moved to various locations on the scale to record EEG signals. All four (A+,A-,B+,B-) electrodes are involved in applying weak electrical pulses back to the brain (feedback process). The brief feedback pulse (\~100mV) is adaptive and determined based on the offset of the frequency spectrum recorded across the left and right hemisphere (A vs. B) electrodes in the time window immediately prior to stimulation.
