A new theory based on possible existence of timing control by intracellular photons in tonically active neurons.

Time perception in living organisms, especially mammals, and understanding the timing of their internal organs, have always been the topic of interest in neuroscience. In this study, our theory considers the photonic behavior on time control by some particular or some block of neurons. Photon emission by mitochondria has regular timing in intercellular process. In other words, due to the main mitochondrial function of cellular respiration as well as the source of photon emission, it is possible to deduce photon at a specific rate in TANs (Tonically Active Neurons). If photoreceptors exist in the neurons of the nervous system, photons can be received at a regulated time. Thereby, neurons can produce a constant-frequency signal for subsequent stimuli. Our studies conducted in the CNS (Central Nervous System) and TANs, and it seems that photoreceptors are present in TANs. Photons are interpreted by a series of neurons and produce an oscillating rhythm. These rhythms can be the basis of the body's chronological activity in different areas of the CNS. If this hypothesis is true, it can be deduced that an independent factor, excluding circadian activities, exists for living activities. Different neuronal structures will also be responsible for understanding the time. Although this hypothesis is far from a complete evaluation, it can compensate for some of the other problems. For instance, a series of inconsistencies that occur in some neurological diseases, such as Parkinson diseases can be well justified by this hypothesis.
