Episode notes
Mitochondria Likely Produce Photons
- Mitochondria are the likely source of cellular photons via electron transfers in metabolism.
- Disrupting the electron chain changes the light emitted, linking photons to metabolic activity.
Neural Activity Boosts Photon Counts
- A dish with ~1 million rat neurons emits ~100 photons/sec at rest and 1,000–2,000 when active.
- Cellular photon counts rise substantially with neural activation.
Prepare For Scientific Pushback
- Expect skepticism when researching unconventional phenomena and prepare for pushback.
- Persist with reproducible data and collaborate internationally to gain acceptance.
