Why do we like rewards? Why do we like sugar? Is sugar addictive? And how is dopamine related to rewards?
This video is all about the neuroscience behind how the brain processes feelings of reward (and punishment). It is more than just dopamine.
We discuss everything from how the brain makes predictions about potentially rewarding outcomes and how we update these predictions, to how we reliably can measure this in the brain. We will discuss brain signals that relate to getting a reward. How the reward size is processed, how the brain deals with unexpected outcomes and how the positive feeling of a reward becomes conscious.
We also talk about the role of dopamine in feelings of reward, and we discuss the topic of addiction in relation to rewards, dopamine, and opiates.
