From the olfactory bulbs, sensory information passes caudally through the large left and right olfactory tracts. Each if these then divides into the medial and lateral olfactory stria, which convey impulses to the opposite and same side of the brain, respectively. A major connection of the lateral stria is with the pear-shaped or piriform cortex, where yet more information processing takes place. From all these structures, nerve fiber bundles ramify throughout the brain, including centers for conscious perception of smell.
ANATOMY The chapter on anatomy describes the gross structure of the canine nose and its evolutionary and developmental origin. Due to centuries of artificial selection for different functions and body shapes, dog breeds, as no other animal species, differ in head and muzzle shape. Long-headed breeds, such as borzois, have extremely long and narrow snouts, whereas bulldogs and other brachycephalic breeds with extremely short noses suffer from overly long palates in proportion to the head, which creates fluttering during breathing accompanied by a stertorous noise.
