Thanks for posting, Xei.

This is where my assumption came from:

I recall reading an article about a study where they hooked up electrodes to a rats brain and were able to induce its brain to release endorphins (or dopamine) which caused it to feel "happy".

They hooked up a lever beside its food and water and the rat could stimulate its brain via electrodes whenever it pressed the electrodes. The rat actually stopped eating and drinking and just pressed the lever over and over until it died. I'm trying to find a link to the story but i'm not having much luck.
