This is your brain on hops. I have no idea what a mouse’s brain would look like.
Welcome to my biannual reminder that less may be more, in this case referring to compounds that create beer aroma.
Some basics
Olfactory receptors are buried in the two patches of yellowish mucous membrane called the olfactory epithelium. Humans have about 20 million receptors, covering the epithelium of both our right and left nostrils. The first stop a collection of molecules otherwise known as an odor makes on the way to the brain, and to being identified as a particular aroma, is in the receptors. Once activated, neurons transmit signals to the olfactory bulb of the brain, which relays those signals to the olfactory cortex. Olfactory information is sent from there to a number of other brain areas, including higher cortical areas thought to be involved in odor discrimination and deep limbic areas. Odor sensation becomes olfactory perception.
