Progress in the Study of Neurobiological Effect on Electromagnetic Field and Its Mechanism
With the rapid development of modern science and technology and the boost of information-based measure,people get more and more opportunities to access to a variety of environments and electromagnetic field(EMF).The issue of EMF on human health draw people's concern.Effects of electromagnetic radiation on the central nervous system in particular high-level cognitive brain function have become the hot point of the study.Researchers have done many years of exploration through the methods of epidemiological investigation and clinical observation,experimental animal research including analysis of the neurobehavioral and morphological changes,neurophysiological and neurochemical changes,and molecular biological changes,and so on.This paper summarized the development of the studies in recent years.
Over half of a human’s brain circuits are devoted to vision and eye movements, making it a system that can be easily compromised by a mild traumatic brain injury (mTBI). Changes in a patient’s eye movements could be a sensitive and objective biomarker of injury, and could also be useful for assessment of the pathways affected by the damage. Here, we discuss the specific dysfunctions found in afferent, efferent, and visual association pathways that may be useful for making a diagnosis of mTBI. Early diagnosis is critical to prevent further injury and to allow appropriate physical and cognitive rest to ensure full recovery, but more research is greatly needed in this area, since diagnosis of mTBI currently relies heavily on subjective complaints.
