2011; Buck and Bargmann 2013). Signals are transmitted mainly to the olfactory cortex, which includes the anterior olfactory nucleus, the anterior and posterior nuclei of the amygdala, the olfactory tubercle, part of the entorhinal cortex, and the piriform cortex (Shipley and Ennis 1996). Pyramidal neurons of the piriform cortex in turn transmit the information indirectly to the orbitofrontal cortex via the thalamus and directly to the frontal cortex. The pathways to higher cortical areas are thought to be important for odor discrimination (Buck and Bargmann 2013).

7a). The two organs each give rise to the tiny fibers of the vomeronasal component of the olfactory nerve, which pass caudally in the nasal septum and converge immediately before passing through the ethmoid bone into the cranium and the vomeronasal parts of the olfactory bulbs of the brain. Although dogs undoubtedly possess a well-developed sense of vomerolfaction, they make less dramatic facial expressions when drawing air into their vomeronasal organs than many species. These expressions are often called the flehmen reaction and are seen mainly in males.

The roof of much of the nasal cavity is formed by the long, thin nasal bones, although the most caudal regions of the dorsal nasal cavities are enclosed by the large frontal bone (Pasquini et al. 1995; Konig and Liebich 2007). 3.
