The influence of low-frequency electromagnetic field on the operability of gray seals

Gray seals are widely used in biotechnical systems for various purposes. In the study of the effect of an artificial electromagnetic field (EMF) with 8 Hz frequency on the performance of gray seals, the method of conditioned reflexes has been used (one of the most informative for experimentally studying the functional state of the higher divisions of the Central nervous system). Two adult female grey seal have been used in the experiment; two series of experiments have been conducted for each individual gray seal. The first series of experiments has been conducted in the conditions of natural (background) geomagnetic field. During the second series of experiments, individuals of gray seals have been affected by an artificial electromagnetic field throughout the training. The criterion for assessing the effect of EMF on the operability of animals is the implementation of skills due to their behavior. During the study, the following parameters of instrumental reflexes have been monitored: the average retention time of the target pointer (the Target command); average target search time (the Search command); total time spent on training; the number of mistakes made by the seal per workout...
