Five Sleep Types Revealed: How Your Brain Wiring Reflects Rest

Summary: A new study has identified five distinct “sleep-biopsychosocial” profiles that connect how we sleep with our brain networks, mental health, cognition, and lifestyle. Using data from over 700 participants,…

Psilocybin Rewire Brain Circuits Tied to Pain and Mood

Summary: New research shows that psilocybin, the active compound in psychedelic mushrooms, can reduce both chronic pain and pain-related depression by modulating brain circuits rather than acting at the site…

Alzheimer’s Study Finds Blood-Brain Barrier Largely Intact

Summary: A new study suggests that the blood-brain barrier (BBB) remains intact in a widely used mouse model of Alzheimer’s disease. Using a tracer molecule and advanced analysis, scientists found…

PET Tracer Maps Synapse Loss After Spinal Cord Injury

Summary: Researchers developed a new PET tracer capable of measuring synapse loss after spinal cord injury, offering insights into both spinal and brain changes. In rat models, the tracer revealed…

Artificial Sweeteners Tied to Faster Cognitive Decline

Summary: A large study of nearly 13,000 adults found that consuming high levels of certain artificial sweeteners is linked to faster declines in memory and thinking over eight years. The…

New Drug Aims to Block Pain Without Addiction Risks

Summary: Chronic pain affects millions, but opioid medications bring high risks of dependence and side effects. Researchers have now pinpointed specific neurons in the amygdala that make pain feel unpleasant,…

Neuron Discovery Could Help Restore Breathing After Spinal Injuries

Summary: Scientists have discovered a specialized group of spinal cord interneurons that help regulate breathing when the body faces challenges like high carbon dioxide levels. Blocking these neurons impaired the…

When Gut Rhythms Over-Sync With the Brain, Mental Strain Rises

Summary: A large-scale study has found that unusually strong coordination between brain activity and the stomach’s slow, rhythmic waves may signal greater mental distress. Using fMRI and electrogastrography on more…

DNA Reveals Multiple Sclerosis Risk Before Symptoms Begin

Q: What is this study trying to discover about MS?A: Researchers aim to understand how genetic risk factors and immune response to the Epstein-Barr virus may interact to trigger multiple…

No Link Found Between Aluminum in Vaccines and Autism, ADHD

Summary: A massive Danish study of over 1.2 million children has found no evidence that aluminum in early childhood vaccines increases the risk of neurological, autoimmune, or allergic disorders. Researchers…
