[The interaction of the thalamic parafascicular complex with the brain stem centers that inhibit locomotor activity].

Effects of electrical and chemical stimulation of the thalamus parafascicular complex on the rat behaviour and functional state of the inhibitory brain stem centres were studied in chronic experiments. The electrical stimulation of the parafascicular complex suppressed the locomotion and augmented multiunit activity in the inhibitory brain stem centres. The lesion of the raphe magnus nucleus and the medial portion of the reticular giganto-cellular nucleus eliminated the inhibition.
