Over the course of evolution our brains have become excellent at detecting rewards (e.g. food or a potential mate) in our environment and in turn generating motivation to obtain that reward. While this system was originally necessary for survival, it can easily become maladaptive in a world where access to rewards (such as high-calorie food, drugs and alcohol, gambling) are present in abundance. Unfortunately, this reward detection system can become hypersentitive in some individuals, in turn causing excessive desire and craving each time they come across a reward cue in their world. This talk addresses how and why this reward system can become dysregulated in some individuals. Answering these questions will help scientists discover new treatment options for individuals living with addiction or psychiatric disorder.
