Endogenous body-brain periodicities and spontaneous behaviors (tapping, walking, speaking) align in a cross-frequency architecture with successive rates spaced by about {varphi}≈1.618 and rhythm-class ratios captured by e≈2.72.
- Why it matters: Behavioral timing may not match arbitrary clock units, leaving open what internal temporal reference frame coordinates precise coordination across body and brain.
- What they did: Using high temporal resolution multimodal recordings, the study analyzed periodicities in pupil fluctuations, saccades, respiration, cardiac activity, neural oscillations, and behaviors, fitting an arithmetic progression in natural logarithmic frequency space.
- The result: Lack of power-law scaling and the failure of harmonic anchoring to individual heart rates argue against a single pacemaker, implying an irrational, largely independent yet dynamically interacting set of rates.
