Separate Neural Systems Value Immediate and Delayed Monetary Rewards Reaction Paper Tuhin Chakraborty These two papers talked about how different neural systems in the brain valued monetary rewards differently based on whether they were received immediately or if they were delayed. More specifically, one also looked at the extent to which subjects were willing to sacrifice some of their reward in order to receive it sooner. I really enjoyed reading these articles because the subject matter is very intuitive. Structures in the brain such as the ventral striatum, medial prefrontal cortex, and posterior cingulate cortex, structures generally associated with planning and controlled action, were the ones activated when presented with delayed monetary rewards. These are the regions activated when we act rationally. For example, if I were to receive $100 today, or $125 two weeks from now, I would probably choose to receive $100 today. But if I were to receive the same amount a year from now, or $125 a year and two weeks from now, I would probably wait the extra two weeks. In reality, however,
