Investigations on the effect of vibration on the neurosecretory cerebral system using 35-S-cysteine.

The investigations were carried out on guniea pigs subjected to vibration of varying parameters and varying duration. Isotope method with 35-S-cysteine administered suboccipitally was used, and the investigated material included supraoptic nuclei and the pars nervosa of the hypophysis. Exposure to vibration was followed by more rapid release of labelled cysteine as demonstrated by reduction in the number of silver grains in autoradiograms.
