Zoning Out or Zoning In? How Aimless Wandering Trains the Brain
Summary: New research reveals that the brain may be learning even during unstructured, aimless exploration. By recording activity in tens of thousands of neurons, scientists found that the visual cortex…
How PTSD Disrupts Brain Cell Communication
Summary: A new study has examined brains affected by PTSD at the single-cell level, uncovering distinct genetic alterations that may drive the disorder. Researchers focused on the dorsolateral prefrontal cortex,…
Why Some People Struggle to Recognize Faces of Other Races
Summary: New research reveals that some individuals may experience selective difficulty recognizing faces from racial groups different from their own, a phenomenon known as category-selective face blindness. While general face…
Facial Expressions Reveal Hidden Cognitive States
Summary: New research shows that facial expressions can reveal internal cognitive states, accurately predicting task performance across both macaques and mice. By analyzing facial features during a foraging task in…
Wellbeing May Help Protect Memory in Middle Age
Summary: A new 16-year study of over 10,000 adults finds that higher wellbeing is linked to better memory performance in middle age. Researchers tracked participants’ psychological wellbeing and memory recall,…
AI Generates Relatable Empathy Experiences
Summary: Researchers have developed an AI tool called EmoSync that boosts empathy by tailoring emotional analogies to each user’s personality and life experiences. Unlike traditional empathy tech that assumes uniform…
Pain Perception in Babies Develops in Stages After Birth
Summary: A new study shows that the networks responsible for processing pain in infants develop gradually, with emotional and cognitive pain responses maturing only after birth. Researchers scanned the brains…
Gut Microbiome May Influence Bipolar Medication Response
Summary: A new review has examined how bipolar disorder medications interact with the gut microbiome, revealing important links between treatment response and gut microbial composition. Researchers analyzed 12 studies comparing…
