Mechanism involved in addictions and some forms of obesity discovered in U of A lab
Date:10/4/2010

showed the same properties as cells found in rats, and they also undergo dopamine-dependent cellular learning when stimulated in the same fashion as the laboratory models.

Considering Colmers and his group's major focus is in obesity, this is a very exciting finding.

"You can find the fridge and you know there's good stuff in there, so you can find it in your sleep, and people do," said Colmers. "So there's this whole reward aspect to place that we've been able to unravel."

These results help explain the mechanisms that underlie the formation of reward-cued spatial memories in both the laboratory model and human dentate gyrus. Understanding this mechanism not only explains the biology of an important form of learning, but may also lead to potential treatments for addiction and obesity.
