I talk with Howard Cromwell who is a neuro scientist at BGSU in Ohio. Howard is well versed in the ways in which dopamine shape our incentives and allow us to progress through an environment of rewards. We talk about the basics of rewards, as well as complications in gambling addiction and drug addiction.
