Peak Brain Institute, a neuromodulation clinic in San Diego, offers neurofeedback therapy and biofeedback therapy supported by quantitative EEG brain mapping. The practice employs a PhD neuroscientist who interprets electroencephalography data to inform individualized neurofeedback protocols targeting attention, anxiety, sleep, and cognitive performance. Treatment focuses on training neural activity patterns rather than pharmacologic intervention, and patients receive real-time feedback during sessions to reinforce desired brain states. The clinic serves patients with ADHD, anxiety disorders, sleep disturbance, and those pursuing cognitive optimization. Care is available in-clinic and remotely, and the practice maintains locations across multiple cities including Los Angeles and New York.
