role of the cerebellum in the control of plasma vasopressin in hypotensive haemorrhage

ABSTRACT

A study was made in anaesthetized cats of the relative roles of buffer nerves and the fastigial nucleus of the cerebellum in the increased release of ADH following haemorrhage in intact cats, a haemorrhage of 20 cc/kg resulted in a significant increase in plasma ADH titer. nevers sectioning resulted in a marked but transient increase in plasma ADH titer, stimulation of the nucleus fastigius of the cerebellum which has a Cardiovascular pressor effect produced a significat decrease in ADH titer, suggesting, for the first time, that the nucleus fastigus of the cerebellum through its sympathoexcitatory pressor pathway is involved in the fluid and electrolyte balance
