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.
Chronic Pain Linked to Neuron Overactivity in the Brainstem
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 pain signals.
Wellbeing May Help Protect Memory in Middle Age
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.
Ketamine Plus Therapy Offers Lasting Relief for Severe Depression
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.
Hope Outshines Happiness as Key to Life’s Meaning
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.
AI Generates Relatable Empathy Experiences
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 deeply. In a study of over […]
