Wageningen: Wageningen scientists drew an unexpected conclusion after experiments
with odours; when smelling bread, test subjects did not choose bread
more often. MRI brain scans of the test subjects did show an effect of
the smell of bread: the reward system in the brain was activated. But
when the test subjects had to choose between standardised images of
white bread, brown bread and cookies, the exposure to the bread aroma
had varying effects. The aroma of bread turned out to increase the
choice for cookies, whereas the smell of warm wood led to a more
prominent preference for brown bread.
