Neurons communicate using light-based signals

Neurons communicate not only through electrical and chemical signals, but also through low-intensity bio-photons. These bio-photons are emitted by neurons and can inform neighboring neurons about their activity state or damage. Different colors of light emitted by these bio-photons carry different messages and stimuli, similar to how neurons communicate chemically and electrically. The use of light in neuronal communication is especially prominent in pathways involving dopamine, serotonin, noradrenaline, and fluorescence. This discovery opens up new possibilities for understanding neurological disorders and developing treatments that enhance and strengthen these light-based communication networks.
