At UT San Antonio College of Sciences, researchers are discovering the connections between stress, hormones, and how to respond to stress disorders between men and women.

Studies suggest that a single stressful event can sharpen how the male brain learns to associate environmental cues with rewards, creating the essential motivational building blocks to master new skills. On the other hand, more prolonged stress can be a deterrent to learning.

After testing this pattern, the research team decided to investigate a new question: Does the female brain respond the same way to stress, and do fluctuations in hormones affect these reactions?
