[The effect of electrical stimulation of the cerebellar fastigial nuclei on local blood flow in the brain].
In acute experiments on unanesthetized cats, continuous recording revealed an increase (30%) as well as a decrease (70%) in local blood flow in the sensomotor cortex of the left hemisphere in response to electrical stimulation (30 Hz, 30 V) of the contralateral fastigial nuclei of cerebellum. The stimulation seems to lead to a primary vasoconstriction as well as vasodilatation of the blood vessels regulating the local cerebral blood flow.
