Fruit flies have a set of neurones that fire only when they encounter real sugar – triggering the release of a hormone that is not released when they eat a non-calorific sweetener. And researchers suggest that humans possess the same ‘molecular machinery’.
Nottingham University researchers have reported improvements to the
method of functional magnetic resonance imaging (fMRI) of the brain
to give scientists a more "natural" insight into the perception of
taste and aroma.
