About this trial
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.
