Caffeinated Decisions: Investigating the Neural Economics of Risk and Reward This laboratory exercise explores the relationship between caffeine consumption and ventromedial prefrontal cortex (VPC) function through a correlational study. Students begin by calculating their daily caffeine intake using an online calculator, then assess their VPC function by completing the Iowa Gambling Task, a decision-making assessment that relies on the ventromedial prefrontal cortex. After obtaining their own
