The Olfactory Pathway

This short clip follows nicely after the clip above. In a similar fashion to the previous clip, the narrator reviews how air passes the olfactory membrane to the cranial nerves, and eventually to the olfactory cortex.

Imagine you are blindfolded and someone places an object under your nose. You are asked to identify it. Suppose you correctly identified the object. How did you do it? Explain the process using what you know about the olfactory pathway.
