Abstract:

Stress influences various types of memory, but its effects on other cognitive functions are relatively unknown. We investigated the effects of uncontrollable stress on subsequent decision-making in rats, using a computer vision-based water foraging choice task. Stress impaired the animals’ ability to bias their responses toward the larger reward when transitioning from equal to unequal quantities, and this stress effect was dependent on the amygdala.
