Jayne E. Moynihan, PhD operates Better Brains Inc. from Carlsbad Village's Harding Street, a neurofeedback and biofeedback practice specializing in brain performance optimization and neurological rehabilitation. Quantitative EEG-guided neurofeedback treats acquired brain injuries, post-concussion syndrome, and stroke recovery through neuroplasticity-based training protocols, a neurorehabilitation focus that aligns with the diagnostic capabilities at The Neurology Center of Southern California - Carlsbad. Clinical populations include children and adults with attention-deficit presentations, missed or misdiagnosed learning disabilities, IQ-related processing discrepancies, and age-related cognitive decline. Ongoing assessment and lifestyle coaching supplement the biofeedback protocols to reinforce gains in sustained attention, executive function, and emotional regulation between training sessions. Optimal-functioning clients — executives, athletes, and students seeking cognitive performance enhancement — use the same neurofeedback technology to sharpen focus and processing speed, a peak-performance methodology that pairs with the physical conditioning programs at Equinox La Costa. The most complex protocols involve multi-channel neurofeedback mapping across 19 or more electrode sites for patients with diffuse traumatic brain injuries, requiring sequential training of individual cortical regions before integrating cross-hemispheric coherence targets.
