Research and Insight
Science-backed articles on bilateral stimulation, EMDR audio, nervous system regulation, and frequency research. Written by Andrew Sorg.
The speed at which bilateral stimulation alternates between ears is one of the most clinically meaningful variables in EMDR audio. Here is what the research says about choosing the right rate for each phase of treatment.
EMDR apps and bilateral audio files serve different clinical functions. Understanding the difference helps therapists choose the right tool for each session context.
174Hz is the most physically grounded of all the solfeggio frequencies. Here is what the research says about its relationship to smooth muscle tension, the vagus nerve, and autonomic regulation.
Between-session bilateral audio use can support nervous system regulation and integration without replacing the therapeutic work. Here is how to use it safely and effectively.
Most frequency stacks called golden ratio are not derived from phi at all. Here is the actual mathematics behind true phi-derived frequency architecture and why it sounds different.
