Figure 1|Schematic diagram outlining the potential modes of biophoton network communication and repair among neurons.
Although the precise function of biophotons is not entirely clear at present, we will focus on two possible actions. First, biophotons may form a major means of communication between neurons. Biophotons emitted by one neuron may inform bystander neurons of their activity state and whether they are functioning normally or are damaged (Figure 1). Their emission could for example, influence many intracellular functions, including mitochondrial activity and energy production, ion channel stimulation and/or permeation at molecular binding sites. This form of communication can be expressed by biophotons using a considerable spectral range (200–950 nm) and different patterns of intensity (i.e., number of biophotons) (Grass et al., 2004; Liebert et al., 2014; Tang and Dai, 2014; Salari et al., 2015; Mothersill et al., 2019; Van Wik et al., 2020; Zangari et al., 2021).
