Enriched Blood Cells Preserve Cognition in Mice With Features of Alzheimer's Disease

July 7, 2015 — Researchers have successfully tested two new methods for preserving cognition in laboratory mice that exhibit features of Alzheimer's disease by using white blood cells from bone marrow and a ... read more

July 2, 2015 — Researchers report that the deletion of the PTEN gene would enhance compensatory sprouting of uninjured CST axons. Furthermore, the deletion up-regulated the activity of another gene, the mammalian ... read more

Sialic Acid: Key to Unlocking Brain Disorders

June 30, 2015 — A common molecule found in higher animals, including humans, affects brain structure, researchers report. They found that mice that had altered sialic acid attachment had significant neurological ... read more

Microtubule 'Roadway' in the Retina Helps Provide Energy for Vision

June 29, 2015 — Researchers have discovered a thick band of microtubules in certain neurons in the retina that they believe acts as a transport road for mitochondria that help provide energy required for visual ... read more

June 29, 2015 — The human retina contains some 100 million photoreceptor cells. When these are stimulated with light, they communicate that information to the brain and we perceive light. Researchers have now ... read more

June 27, 2015 — A specific calcium channel plays a crucial role in deep, slow-wave sleep, scientists have discovered. This is a key step toward understanding both normal and abnormal waking brain ... read more

June 26, 2015 — Studies on mice reveal that a special protein in the brain's tiniest blood vessels may affect the risk of stroke. Scientists are learning how the blood-brain barrier develops and what makes the ... read more

June 25, 2015 — A study supports a surprising alternative approach to controlling asthma: targeting certain sensory nerve endings in the lungs. The researchers show that specialized sensory neurons called ... read more

What Controls Blood Flow in the Brain?

June 25, 2015 — Scientists present the strongest evidence yet that smooth muscle cells surrounding blood vessels in the brain are the only cells capable of contracting to control blood vessel diameter and thus ... read more

Therapy Affects the Brain of People With Tourette Syndrome

June 25, 2015 — In addition to its effect on chronic tics, cognitive behavioural therapy (CBT) can change the brain function of people with Tourette syndrome, new research confirms. Tourette syndrome is a ... read more

Redrawing the Language Map of the Brain

June 25, 2015 — For 140 years, scientists' understanding of language comprehension in the brain came from individuals with stroke. But now they have redrawn that brain map based on new research with individuals ... read more

June 24, 2015 — Scientists have profiled key features of the genetic material inside three types of brain cells and found vast differences in the patterns of chemical modifications that affect how the genes in each ... read more

Atlas of Older Brains Could Help Diagnosis of Alzheimer's Disease

June 24, 2015 — A digital map of the aging brain could aid the diagnosis of Alzheimer's disease and other neurodegenerative disorders in older people, a study suggests. The atlas created using images from MRI ... read more

June 23, 2015 — Ten weeks of intensive reading intervention for children with autism spectrum disorder was enough to strengthen the activity of loosely connected areas of their brains that work together to ... read more

Quiet That Ringing in the Brain

June 23, 2015 — Epilepsy and tinnitus are both caused by overly excitable nerve cells. Healthy nerves have a built-in system that slams on the brakes when they get too excited. The 'brakes' are actually ... read more

Parkinson's Disease May Begin in the Gut

June 23, 2015 — A major epidemiological registry-based study indicates that Parkinson's disease begins in the gastrointestinal tract. The study is the largest in the field so ... read more

New Light Shed on How Neurons Control Muscle Movement

June 23, 2015 — Researchers studying how the brain controls movement in people with paralysis, related to their diagnosis of Lou Gehrig's disease, have found that groups of neurons work together, firing in ... read more

First Genetic Mutation Associated With Aicardi Syndrome

June 19, 2015 — A genetic mutation responsible for a debilitating childhood neurological condition known as Aicardi syndrome has been identified by researchers. They identified mutations to a gene known as TEAD1, ... read more

June 19, 2015 — The thickness of the brain's cerebral cortex could be a key to unlocking answers about intellectual development in youth with Down syndrome. It could also provide new insights to why individuals ... read more

June 19, 2015 — Mapping the human brain's network of interconnections, known as the connectome is typically done with help from computational tools because recreating interconnections between different brain ... read more
