And this made animals eat five times more than normal.
It would make the rats eat eight times more than normal.
And people thought they ate more because they liked the food more.
But when we looked at the facial expressions, they didn't like the food more.
In fact, they kind of showed a little more disgust, but they still ate eight times more than usual.
All right.
You say the one liking thing is it's probably fair to say the field didn't believe us for about 10 years, but then some drug studies, clever drug studies by a number of people.
One great example is Marco Layton in Montreal in the early 2000s.
He was giving people volunteers who would participate in the study.
They could get free.
And he asked them, how much do you like this cocaine?
And how much do you want to take a little bit more cocaine once you've taken this first dose?
And he gave them low dose or medium dose or high dose.
And the higher the dose they took, the more they liked the cocaine.
It made sense.
And the higher the dose they took, the more they wanted to take even more cocaine.
It makes you want it even more.
Well, this is half the study.
The second half is he gave them the cocaine, but he simultaneously suppressed their dopamine with a dopamine-blocking drug.
And when he now asked them, how much do you like the cocaine and how much do you want it?
