The Lateral Olfactory Tract, the Anterior Commissure, and Other Olfactory Connections
Although all complex organisms utilize multisensory input to monitor the external environment, each species appears to have one system which is predominantly used. For man and most avian species, the dominant sensory system is vision. For rats and many other species of rodents, the dominant sensory system is olfaction. It is necessary to consider the olfactory system in some detail not only because it represents the primary source of sensory input for the rat, but also because of its close interrelationship with the structures of the limbic system; the notion that the primary function of the limbic system (rhinencephalon) was to process olfactory information is also of historical importance (cf. Chapter 1 and Brodai, 1947).
