Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that gambling addiction has a primary dopaminergic basis in the brain?

Yes. Multiple peer-reviewed studies and clinical literature establish that gambling addiction shares a neurobiological basis in the brain's reward system, where dopamine and dopaminergic pathways play a central role in reward signaling and reinforcement.
