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, a brain region tied to emotional regulation, analyzing individual cell nuclei to map communication differences across PTSD, major depression, and...
Why Some Individuals Attempt to Recognize Heads of Another 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 blindness (prosopagnosia) is well-documented, this study shows that many people perform well with own-race faces but poorly with others.The researchers...
Hidden Mental State Are Discovered by Facial Emotions
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 a virtual reality setup, researchers identified patterns linked to motivation, focus, and responsiveness.These patterns were consistent across species, suggesting a...
Neuron Overactivity in the Medulla is Related to Chronic Pain
Summary: A new study reveals that neurons in the brainstem respond very differently to acute versus chronic pain, potentially explaining why some pain persists long after injury. In acute pain, neurons in the medullary dorsal horn reduce their activity through a natural “braking” system involving A-type potassium currents, helping limit...
New Autism Data Provides New Evidence on New Circumstances
Summary: Researchers have released genetic and behavioral data from over 1,500 children and adolescents with autism who were hospitalized in psychiatric units across the U.S. This group, often representing those with profound autism—marked by minimal language and high support needs—has been largely missing from previous datasets.The new release includes rich...
In the Middle Ages, Wellbeing Does Support Protect Memory.
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, finding that those with higher life satisfaction were more likely to retain stronger cognitive function over time.This effect persisted even...
KETMA PLUS Therapy Provides Long-Term Relief for Serious Depression
Summary: A first-of-its-kind clinical trial shows that ketamine treatment for severe, treatment-resistant depression is significantly more effective when paired with psychotherapy and supportive environments. Patients who underwent this combined treatment reported a 30% drop in depression symptoms, with reduced anxiety and suicidal thoughts lasting at least eight weeks.Those who experienced...
Expect defeats delight as the key to the meaning of life.
Summary: Hope isn’t just about wishful thinking—it’s a unique emotional experience that may be more essential to well-being than happiness or gratitude. A new study shows that hope stands out among positive emotions as the most consistent predictor of a meaningful life.Researchers analyzed responses from over 2,300 participants across six...
AI Produces Realistic Empathic Experience
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 emotional responses, EmoSync uses a large language model (LLM) to map personal traits and generate custom scenarios that resonate more...
Children ‘ perception of pain develops in periods 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 of 372 infants, primarily born prematurely, to track how three brain subsystems related to pain perception matured over time.While babies...
