I was expecting it would be just a low level feature detector since smell is like like a bag-of-words format (unordered) while vision is at least 2D (space) and hearing 1D (time).
I'm definitely glad we have this feature first thing in the morning before brushing my teeth!
Fun to watch this work when my dog is ratting for voles in the yard.

It's all well and good to have awesome algorithms for detecting X, Y, or Z in a stream of stimuli but it's smell that tells us which things to anticipate.
