woman: 
Yeah, synthetic smells are so fake.
Man:
Well, they’ve done tests, and take for 
example, lime essential oil which is sharply 
intense. The vast majority of subjects 
in the lab actually identify it as smelling 
chemical, while the artificial odour lime 
oxide is seen as smooth and natural. And 
there’s this chemical that has an almond-
like smell, and it’s universally seen as 
natural, apart from by chemists and chefs.
woman:
How interesting. So, was the programme 
all about smell then?
Man:
It was a big focus. It also dealt with human 
and animal brains. Way back, there was 
this scientist who found that the brain 
region in humans that processes odour 
detection is smaller, relative to total brain 
volume, than in dogs or rats. New findings 
show the number of neurons, you know 
nerve cells in the brain, related to smell is 
remarkably consistent across mammals.
