Sleep-Deprived Fruit Flies Show Sharper Memory via PKA Signaling

by

Summary: Fruit flies with genetic mutations that severely reduce sleep show enhanced performance in olfactory memory tasks, challenging assumptions about sleep’s role in cognition. This paradox appears to be driven by increased protein kinase A (PKA) signaling in the mushroom body, a brain region responsible for memory and sleep regulation. The study suggests that heightened … Read more

Stressed? Your Brain Might Be Playing Tricks on Your Hearing

by

A week of stress changed how mice processed sound, making them less sensitive to loud noises. The study revealed altered brain activity in key auditory regions, suggesting stress reshapes perception, not just emotions. Stress doesn’t just affect emotions — it changes how we perceive the world. A study found that mice exposed to a week … Read more
