For instance, Dorman notes that half of the nasal cavity of a rat is lined with olfactory-system cells. In humans, this receptive area is much smaller, he says - "only about 3 to 5 percent."
The projection of the ventral tegmental area (VTA) to the olfactory tubercle(OT) was studied with in 20 rats with retrograde axonal transport of hoseradish peroxidase(HRP).

The ventral tegmental area is another source of centrifugal fibers to the olfactory bulb.
