[Characteristics of the effects of the midbrain reticular formation on the heart and respiration in exposure to centripetal accelerations].
Experiments were carried out on white rats and rabbits exposed to transverse accelerations of 6--10 g for 5 min. Before, during and after centrifugation the reticular formation of the midbrain underwent high-frequency electric stimulation. During centrifugation the inhibitory effects of the reticular formation on the cardiorespiratory rhythm decreased, whereas stimulatory effects either remained unchanged or increased.
