Sense of Adventure Rests in Primitive Brain Region
Date:6/25/2008

The brain's reward system for making novel choices could have even more serious consequences, said study co-author Professor Nathaniel Daw.

"The novelty bonus may be useful in helping us make complex, uncertain decisions, but it clearly has a downside. In humans, increased novelty-seeking may play a role in gambling and drug addiction, both of which are mediated by malfunctions in dopamine release," Daw said.

The study was published online in Neuron.

The National Institute of Neurological Disorders and Stroke has more about the brain.
