Not the first study to come up with something like this, but apparently the first that looks directly at reaction in the 'reward centre' of the brain. I can't remember undergrad psychology well enough to know how sceptical to be about this.

It would be interesting to see if the same results would pertain if the reward being given was say, chocolate, or sex. (More detailed report on Medicexchange.com)
