title: Spatial interactions of opposite vasomotor reflexes.
abstract: The simultaneous interactions of pressor and depressor reflexes evoked by stimulation of the central ends of the vagal, tibial and median nerves were studied in urethan and chloralose-urethan anaesthetized cats. The responses obtained to simultaneous activations of opposite reflexes differed from the algebraic sum of the separately evoked ones. The direction and the extent of the differences were determined by the type of the prevailing neural process and by the size of the individual reflex responses. The relations between the responses evoked simultaneously and separately may be characterized by multiple linear regression.
