Figure 1 Stress-Induced Changes in Decision-Making (A) Just like humans, rats exposed to chronic stress make more “high-reward but high-cost” choices. (B) Friedman et al. (2017) reveal changes in striatal circuits that contribute to altered decision-making. While it has been well established that stress weakens the “top-down” influence of the prefrontal cortex, this study revealed the consequences on striatal physiology, where reduction in feed-forward inhibition by fast-spiking interneurons led to stronger striatal output from the projection neurons in striosomes, driving more high-risk/high-reward choices.
