Slowest Shared Resonance (SSR) between coupled neural clusters.

Coupled system	Slowest Shared Resonance (SSR)	Estimated distance**
Retinal-brain	3–4 Hz	5 cm
Olfactory-brain*	0.16–0.33 Hz	7–10 cm
Cardiac-brain	0.1 Hz	30 cm
Gastric-brain	0.05 Hz	50 cm
Corticospinal-brain	N/A	15–50 cm (wide range due to length of spinal cord)

*Tentative placement.

**Rough estimate provided in normal stature adult human, provided for illustration only. Additional research is required to provide better estimates.
