If you are attempting to view the olfactory bulbs on a preserved specimen, they may be missing or incomplete. Then this might be a case of congenital anosmia.
A good sense of smell depends on the olfactory bulb since it sends scent information from the nose to the brain. Olfactory receptors are activated by scent molecules, and signals are sent up the olfactory nerves to the olfactory bulb and then via the olfactory tract to the rest of the brain.
People with congenital anosmia are born without the sense to smell, which affects them for the rest of their lives. It may manifest alone (with no further symptoms) or in connection with a particular genetic condition (such as Kallmann syndrome or congenital insensitivity to pain).
