Scientists identify new brain circuit in mice that controls body’s inflammatory reactions

The brain can direct the immune system to an unexpected degree, capable of detecting, ramping up and tamping down inflammation, shows a new study in mice from researchers at Columbia’s Zuckerman Institute. “The brain is the center of our thoughts, emotions, memories and feelings,”…

Sleep resets brain connections — but only for first few hours

During sleep, the brain weakens the new connections between neurons that had been forged while awake — but only during the first half of a night’s sleep, according to a new study in fish by UCL scientists. The researchers say their findings, published in…

Neuroscientists Reveal Secret of Superagers’ Excellent Memories

Neuroscientists Reveal Secret of Superagers' Excellent Memories

People who still have very sharp memory into old age—known as “superagers”—may get their impressive powers from certain areas of the brain being preserved. Brain structures known as white matter usually decline in integrity with age, but in superagers, white matter remains structurally sound,…

hNSC transplantation alters microglial cell signaling in the brain of 5XFAD mice after 34 weeks. Circle plots of ligand-receptor pair interactions between cell types with hNSCs as (A) sender and (B) receiver in the brain of hNSC injected 5XFAD mice. Circle plots of differential…

New study reveals microplastic chemicals can enter the human body through sweat

New study reveals microplastic chemicals can enter the human body through sweat

A recent study conducted at the University of Birmingham in the United Kingdom has found that chemical additives within microplastics can infiltrate the human body through sweat . Microplastics, tiny particles measuring a millionth of a gram, are present in virtually everything humans consume…

Definitive Therapy to the Primary Site Improves Survival in Brain-Only Metastatic NSCLC

Definitive Therapy to the Primary Site Improves Survival in Brain-Only Metastatic NSCLC

0 TOPLINE: In patients with non–small cell lung cancer (NSCLC) who have metastases to the brain only, definitive treatment to the primary site improved overall survival outcomes following stereotactic radiosurgery, a retrospective analysis found. METHODOLOGY: The American Society of Radiation Oncology guidelines strongly recommend…

New studies examine the effects of napping on infant and preschooler brain development

New studies examine the effects of napping on infant and preschooler brain development

A University of Massachusetts Amherst sleep scientist, funded with $6.7 million in grants from the National Institutes of Health (NIH), has launched two unprecedented studies that will track over time the brain development of infants and preschoolers to confirm the role of napping in…

Brainless memory makes the spinal cord smarter than previously thought

Aya Takeoka at the RIKEN Center for Brain Science (CBS) in Japan and colleagues have discovered the neural circuitry in the spinal cord that allows brain-independent motor learning. Published in Science on April 11, the study found two critical groups of spinal cord neurons,…

Neuroscientists Warn of ‘Cascading’ Alzheimer’s Risk From These Two Habits

Neuroscientists Warn of 'Cascading' Alzheimer's Risk From These Two Habits

Two common habits could be putting you at an increased risk of Alzheimer’s and related dementias, neuroscientists have warned. Alzheimer’s disease affects roughly 5.8 million Americans, according to the Centers for Disease Control and Prevention. The progressive condition is the most common form of…
