How to Teach AI to Adapt

featured 69972

Summary: Researchers have developed an AI-inspired neural model that mirrors how the prefrontal cortex uses gating to regulate information flow between neural regions. This framework improves adaptive learning and could guide more brain-like artificial intelligence systems. Source: Salk Institute Teaching computers to think and learn like humans remains a central goal in artificial intelligence. Human … Read more

Why We Crave Sugar: The Science of Sugar Cravings

featured 27240

Scientists have long blamed sugar’s sweet taste and high calorie content for undermining diets. A new study from Yale University, however, shows that the brain processes taste and calories in distinct ways, and that only the calorie-driven response reliably predicts why people often abandon diet goals. The research, published Jan. 25, 2016 in the journal … Read more

How Sensory Pathways Detect and Respond to External Temperature

featured 42571

Summary: By selectively disabling specific brain regions in rats and observing the animals’ preferred ambient temperatures, researchers clarified how distinct neural pathways contribute to sensing and responding to external temperature. These findings advance understanding of thermoregulation and may shed light on disorders such as heatstroke. Source: Nagoya University. Maintaining a stable body temperature requires coordinated … Read more

Summary: Researchers report that a very low dose of the anti-cancer drug romidepsin reduced social deficits in animal models of autism. Source: University at Buffalo. Social difficulties are among the most disabling features of autism spectrum disorder (ASD), and currently no approved treatment directly targets these core symptoms. New research from the University at Buffalo … Read more

Eye-Tracking Study Reveals How Autism Alters Social Attention

featured 99391

Summary: Researchers report that children with autism spectrum disorder (ASD) develop distinct visual attention patterns compared with typically developing children, tending to focus more on non-social elements—objects, textures and irregularities—than on faces and social interactions. A longitudinal eye-tracking study in which children watched short cartoons showed that, unlike typically developing peers who converge toward similar … Read more

Study: Traffic Noise Linked to Higher Tinnitus Risk

Summary: New national research finds that people who live near heavy road traffic and are exposed to higher residential noise levels face an increased risk of developing tinnitus. Source: University of Southern Denmark Living close to a busy road can raise stress levels and disrupt sleep. Prolonged stress and poor sleep quality are known contributors … Read more

Beyond Caffeine: How Coffee Boosts Brain Readiness and Focus

featured 95117

Summary: Drinking a cup of coffee produces changes in brain connectivity that make people more alert and better prepared to shift from rest to task-focused activity — effects that are not fully reproduced by caffeine alone. A group of Portuguese researchers reported that a standard cup of coffee reduced connectivity within the brain’s default mode … Read more
