Location
The olfactory bulb sits just intracranially to the cribriform plate. It receives input from olfactory nerves located in the nasal epithelium.
Branches
At its posterior margin, the olfactory bulb becomes the olfactory tract.
Supplied Structures
The olfactory bulb is sensory, organizing and conveying the sense of smell. Fibers from the olfactory bulb travel posteriorly in the olfactory tract to reach the olfactory cortex in the temporal lobe of the brain.

Olfactory Bulb
In the OB, axons from ORNs that express single odorant receptor genes segregate into small subsets of glomeruli (Figure 20.1), the specialized accumulation of dendritic neuropil that receives direct ORN input.
