Photons detected in the active nerve by photographic technique

" Several studies focused on the possible role of photons in neural communication and provided evidence of the transfer of photons through myelinated axons. A hypothesis is that myelin sheath would behave as an optical waveguide, although the source of photons is controversial. In a previous work, we proposed a model describing how photons would arise at the node of Ranvier. In this study we experimentally detected photons in the node of Ranvier by Ag+ photoreduction measurement technique, during electrically induced nerve activity. Our results suggest that in association to the action potential a photonic radiation takes place in the node." {Credits 1}

" Consequently the most probable wavelength spectrum of propagation should fall in the interval 700–1800nm. Taking into account the absorption efects above 1600nm [4,30], the useful bandwidth probably reduces to 700–1600nm." {Credits 1}
