Brain, eyes, light: biological electrical magnetism of light and neurorehabilitation of cognitive impairment

Biological electrical magnetism of light and neural networks of the brain is the adaptation and optimization of external and internal lighting conditions (type, nature, duration) to improve the cognitive brain. Homo sapiens brain operates in a 24-hour biological electrical magnetic environment. Light is the strongest synchronizing signal for the circadian system, and therefore keeps most biological and psychological rhythms internally synchronized, which is important for the optimal functioning of H. sapiens brain. Circadian Sleep-Wake disorders and chronic circadian misalignment, often seen in psychiatric and neurodegenerative diseases, may be effective in neurorehabilitation of cognitive impairment. Beneficial effects on circadian synchronization, sleep quality, mood and cognitive performance-depend on the time, intensity and spectral composition of light exposure. Multidisciplinary and multimodal interaction in the triad ‘brain-eyes-vessels’ allows to identify early biomarkers of both General accelerated and pathological aging, and timely diagnose neurodegeneration, and conduct effective neurorehabilitation of cognitive disorders...
