[Pituitary hormone secretion induced by optokinetic stimulation (author's transl)]

A slight optokinetic stimulation induces a significant increase of serum levels of antidiuretic hormone 1,1 +/- 0.8 pg/ml (mean +/- SD) to 3,3 +/- 1,9 pg/ml (mean +/- SD). Serum levels of gGH and cortisol remain unchanged, whereas serum prolactin levels decrease slightly. The ADH secretion seems to be the most sensitive hormonal parameter of the stimulation of the vestibular nuclei induced either by the optokinetic stimulation or by the Coriolis effect.
