Proof: The superior method for enhancing neuroplasticity in adults is neurofeedback
training compared to exercise or sleep optimization.
Generated: 2026-03-27
Verdict direction: DISPROOF — evidence from peer-reviewed meta-analyses shows exercise
has stronger, more replicated, mechanism-linked neuroplasticity effects than neurofeedback,
