Triggered Hypothermia Protects the Brain After Injury
Summary: Scientists have discovered a way to induce a hibernation-like state that protects the brain after injury—without using external cooling. By activating a specific population of neurons, researchers created a…
Inflammatory Brain Cells Driving Progressive MS Discovered
Summary: Researchers have identified a rare type of brain cell that may drive the chronic inflammation and neurodegeneration seen in progressive multiple sclerosis (MS). These cells, called disease-associated radial glia-like…
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…
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…
