We just learned about the Olfactory Bulb.
Another part of the way humans smell is the Primary Olfactory Cortex.
This is the last part of the brain that takes the messges from the Olfactory Bulb, figures out what the smell is that you are smelling, and tells the rest of your brain whether it is a good smell or a bad smell!
