Projekt

The use of modern technologies such as mobile phones results in the exposure of the human brain to artificial blue light and electromagnetic radiation (EMR), which are distinct from the natural stimuli that our brains have evolved to respond to over the course of evolution. Although the effects may not be immediately apparent, it is probable that our brains are being affected in ways that are not yet fully understood. The project team is utilizing animal model experiments to investigate the effects of overexposure to blue light and EMR on the brain. The project team is focusing on oligodendrocytes and the development of myelin, which protects nerve cells. If these oligodendrocytes are damaged or stressed, this can have a negative impact on the neurons. The current studies indicate that in these cells, the protein cryptochrome, which is capable of sensing light and magnetic fields, malfunctions when there is an excess of blue light and EMR. The project's objective is to bridge the knowledge gap regarding the molecular effects of artificial blue light and EMR exposure on myelin development, thereby providing insights into brain health in the present era.
