Abstract

The paper reports the results of the study on the influence of weak low-frequency magnetic fields on human vision. In particular, it determines the primary magnetic fields frequency ranges that cause magnetobiological reactions, i. e., individual contraction of oculomotorius muscles. The magnitude of magnetic fields did not exceed 300 μT, which makes it possible to classify such fields as safe for human health according to the current legislation. Exposure of eye motoneurons to an external alternating magnetic field causes reactions on the part of specific oculomotorius muscles that are identical to their reactions under natural motoneuron control. Neurons located at other hierarchical levels show more complex reactions in which several oculomotorius muscles take part. The study found that the frequency of oculomotorius muscles ranges from 40 to 85 Hz. Each neuron can be characterized by its ‘frequency range’ of external magnetic control. Hence, the knowledge of frequency ranges for all neurons of a particular control system not only allows the possibility of external control of such a system, but also the possibility of its diagnosis by means of external noninvasive examination. The conducted research is another contribution into weak fields magnetobiology. It aims to create alternative noninvasive technologies for practical medicine.
