Summary: Up to 90% of people with Parkinson’s disease experience a reduced sense of smell, often years before motor symptoms appear. New research from Yale identifies biological changes in the olfactory system that explain this early loss of smell: mice engineered to model Parkinson’s show severe pathology in the projection neurons of the olfactory pathway … Read more

What do they possess that others might lack, and can it be measured? One common explanation is high emotional intelligence (Mayer & Salovey, 1993). Emotional … Read more

Summary: A new meta-analysis has identified a distinct brain network that connects the diverse patterns of brain atrophy observed in schizophrenia. Analyzing neuroimaging findings from more than 90 published studies and over 8,000 participants, researchers generated an atrophy-connectivity map that converges on regions long implicated in schizophrenia—most notably the insula, hippocampus and fusiform cortex. This … Read more

For people who sleep well, emotional intensity linked to embarrassing or … Read more

The study found no clear preference for a generous person over a … Read more

Summary: New research adds to evidence that chronic, low-grade inflammation during pregnancy is linked to a higher risk of neurodevelopmental delays in children. Source: Elsevier Obesity, diabetes, high blood pressure, depression and anxiety during pregnancy are associated with greater odds of learning difficulties, behavioral problems and early mental health concerns in children. A study published … Read more

Summary: Researchers report that adaptive music systems that sync tempo and rhythm to a user’s movement can make exercise more enjoyable and more motivating. These personalized interactive music systems (PIMSs) use real‑time data from wearables and smartphones to align musical features with walking, cycling, or strength training intensity, helping users keep time, maintain effort, and … Read more
