Biophotons as neural communication signals demonstrated by in situ biophoton autography

" Cell to cell communication by biophotons has been demonstrated in plants, bacteria, animal neutrophil granulocytes and kidney cells. Whether such signal communication exists in neural cells is unclear. By developing a new biophoton detection method, called in situ biophoton autography (IBA), we have investigated biophotonic activities in rat spinal nerve roots in vitro. We found that different spectral light stimulation (infrared, red, yellow, blue, green and white) at one end of the spinal sensory or motor nerve roots resulted in a significant increase in the biophotonic activity at the other end. Such effects could be significantly inhibited by procaine (a regional anaesthetic for neural conduction block) or classic metabolic inhibitors, suggesting that light stimulation can generate biophotons that conduct along the neural fibers, probably as neural communication signals. The mechanism of biophotonic conduction along neural fibers may be mediated by protein–protein biophotonic interactions. This study may provide a better understanding of the fundamental mechanisms of neural communication, the functions of the nervous system, such as vision, learning and memory, as well as the mechanisms of human neurological diseases."

In the experiments apart from an anesthetic they also used a metabolic inhibitor, using both (anesthetic and metabolic inhibitor) cause quenched completely biophotonic activity, but using one solely don't suppress activity completely suggesting that the observed biophotonic signals after light stimulation consist of two components: action and background biophotons.

It can be taken into account that procaine affects microtubule polymerization / depolymerization, and that microtubules are believed to act as optical fibers for biophoton propagation along axons.

Anyways the authors propose a biophoton propagation through protein-protein interaction, where two different proteins may achieve biophotonic conduction if they form a biophotonic interaction couple, meaning that one protein absorbs a certain spectral biophoton (for example 630 nm) and emits another spectral biophoton (for example 670 nm). In contrast, the other protein of the couple absorbs 670 nm biophotons and emits 630 nm biophotons. In this way, 630 and 670 nm biophotons can conduct along a neural fiber if the protein couple is distributed and assembled in the neural fiber.

On the other hand they remind us that there is experimental evidence for a correlation between biophotonic activity and the EEG activity.
