What Happens To Your Brain Under Stress?

Ever wonder what stress actually does to your brain? In my neuroscience lab, we intentionally stress people out (ethically, I promise!) to watch how their brains respond. In this video, I’ll show you what happens inside the Trier Social Stress Test—a classic experiment where participants must give a 5-minute speech to judges who refuse to smile or react. Their brains flood with cortisol, performance plummets, and something fascinating unfolds: • The hippocampus, your memory hub, shuts down under stress. • The amygdala, your threat detector, ramps up. • Memory for neutral details collapses—but memory for negative ones strengthens. You’ll learn how evolution shaped this bias to protect us, and why in today’s world of chronic stress, that same system can quietly rewire your brain toward negativity. 🎓 What you’ll learn: ✅ How the Trier test induces real stress safely ✅ Why emotionless faces feel threatening ✅ The neuroscience behind performance anxiety ✅ How chronic stress trains your brain to over-focus on the negative If you’ve ever frozen during a presentation or fixated on what went wrong, this will make you see your brain—and yourself—differently. #Neuroscience #Stress #Memory #Students #Learning #BrainScience #Psychology #CollegeLife
