If you've ever been to Las Vegas, you're well aware of the unique scents of the various casinos & hotels up and down The Strip.  In fact, if you ask people what one of their favorite parts of Vegas is, they'll tell you "it's the smell inside the casinos".  And it seems that everyone has their own preferred scent - so much so, that there are thousands of posts online from people asking how to either purchase or duplicate their favorite casino scent.

But what's the big deal about smell?  Why is the scent of a casino so important that the companies that own them spend MILLIONS of dollars on creating these so-called "signature scents"?

To get the answer, I decided to talk to an expert...

My guest for this episode is Dr. Rachel Herz, a world-renowned expert on the psychological science of smell.  Dr. Herz is a cognitive neuroscientist, a TED-X speaker and a published author of both numerous research publications and several books on the topic of the science of smell.

We discussed what piqued her interest in the psychology of scent, the connection between scent and emotion & memory and how businesses use scent to affect customer behavior.

To learn more about the science and psychology of scent, visit Dr. Herz's website or follow her on Twitter.  You can also pick up one of her books:

• "The Scent Of Desire: Discovering Our Enigmatic Sense Of Smell"
