[Vegetative reactions of dolphins to a change in the permanent magnetic field].
Vegetative responses of dolphin to changes in permanent magnetic field were studied. Electrocardiograms, cutaneogalvanic reactions, and respiration were registered. These parameters were compared with the functional behavior of dolphin: motion, sharp frequent expirations, and acoustic activity. Functional responses to permanent magnetic fields of 32; 108 and 168 microT were registered in 79.2, 63.3 and 52.9% of presentations, respectively. The frequency of responses in control at a power of geomagnetic field of 48.5 microT was 32.7%. Five latent periods were observed in the response of dolphin to changes in magnetic field (72% of responses). It is shown that dolphins have a high responsiveness to changes in permanent magnetic field "magnetic sense").
