[The functional asymmetry of the olfactory control of visceral functions]

In amphibia (frogs) and mammals (rats, guinea pigs, cats), unilateral electrical stimulation of olfactory lobes or section of olfactory tracts resulted in considerable functional changes in respiratory and cardiovascular systems, the olfactory influences being functionally asymmetric. Possible interactions of asymmetric influences at the level of truncal visceral centers, are discussed.
