Fibers in the anterior commissure control the olfactory regions in each hemisphere.
2.
Olfactory regions, which are in the paleocortex, are also in some ways more primitive, so they are simpler.
3.
The enlarged olfactory region of ankylosaurids indicates a well-developed sense of smell, and the position of the orbits of " Ankylosaurus " suggest some stereoscopic vision.
4.
In neural terms, there are only two major olfactory regions in the brain : the olfactory bulb and the pyriform cortex, with a few small accessory structures.
5.
Olfaction is very interesting in that the primary olfactory region, the olfactory bulb, is almost miraculously similar to the primary olfactory regions of insects, which almost certainly evolved separately.

7.
Though it had large nostrils and a fleshy snout, " Nigersaurus " had an underdeveloped olfactory region of its brain and thus did not have an advanced sense of smell.
