Ultraweak Photon Emission in the Brain
Keywords:
Brain, Ultraweak Photon Emission, Biophotons, Neural Metabolism, Oxidative Stress, NeuroimagingAbstract
Ultraweak photon emission (UPE) or biophoton emission is a spontaneous emission of low intensity photons by living cells as a byproduct of metabolic and oxidative activities. According to recent research, the brain being a high metabolism and oxidative environment is a significant source of UPE. Though the amount of these emissions is nowhere near the threshold that the human eye can sense, the emissions can be sensed with a sensitive photomultiplier tube or charge-coupled device, which offers a potential non-invasive look at the functioning of the neuron and systemic oxidative stress. In this view, the mechanistic basis of the brain UPE with a particular focus on its connection with the reactive oxygen species production, mitochondrial activity, and cellular signaling pathways is explored. We will talk about the possible relationship between UPE intensity and changes in neuronal metabolic states, neuroinflammatory conditions, and oxidative burden and present a possible biomarker of neurological activity and disease. Moreover, the article addresses the theoretical consequences of UPE in brain monitoring, such as the opportunities of optical-based neuroimaging, the early diagnosis of neurodegenerative diseases, and real-time evaluation of the treatment mode. The problems of measuring such as signal-noise constraints, standardization of detection procedures and environmental interference are also identified to guide future studies. Given that such synthesis of current evidence and conceptual frameworks, this perspective will be used to offer a foundation to integrate brain UPE into experimental and clinical neuroscience. Further development of the given field could eventually allow new methods of diagnostics and monitoring, as well as allow us to learn more about the physiology and pathophysiology of the brain under the influence of non-invasive optical signals.
