Neural biophotons and animal intelligence

Spectral measurements of biophotons, ultraweak light emitted by cells, in brain slices stimulated with the neurotransmitter glutamate revealed that the wavelengths of biophotons generated by neural circuits are shorter in animals—bullfrog, mouse, chicken, pig, and rhesus monkey—than humans, suggesting that this property might be associated with neural signal transmission and processing in humans as well as humans’ relatively higher intelligence compared with other animals, according to a study. - Read at PNAS.org
