Mammalian brains, with their unmatched number of nerve cells and density of communication between them, are the most complex networks known. While methods to analyze neuronal networks sparsely, accessing about one in every ten thousandth nerve cell have been available for decades, the dense mapping of neuronal circuits by imaging each and every synapse and...

Escaping Alzheimer’s
There is, in Colombia, a family with a tragic legacy of forgetfulness. “People in this large family get Alzheimer’s like clockwork at age 45-50,” said UC Santa Barbara neuroscientist Kenneth S. Kosik, the campus’s Harriman Professor of Neuroscience and co-director of the Neuroscience Research Institute. Their aggressive, genetic form of the disease has been passed...

The first test to detect dysphagia in patients with cognitive problems
by University of Granada Researchers from the Mind, Brain and Behaviour Research Centre (CIMCYC) of the University of Granada (UGR) have designed a test to detect dysphagia, a disorder that prevents people from swallowing when eating. It affects 8 percent of the world’s population. Dysphagia is prevalent among older people in particular (30 percent to...

New insights into how the brain perceives and processes odors
by Society for Neuroscience New research makes advances in understanding how smells are perceived and represented in the brain. The findings were presented at Neuroscience 2019, the annual meeting of the Society for Neuroscience and the world’s largest source of emerging news about brain science and health. Olfactory cues provide essential information for finding food, navigation, predator avoidance, and social...

Polymerized estrogen shown to protect nervous system cells
Research could enable improved treatment of spinal cord injuries RENSSELAER POLYTECHNIC INSTITUTE TROY, N.Y. — Spinal cord damage that causes paralysis and reduced mobility doesn’t always stop with the initial trauma, but there are few treatment options to halt increased deterioration — and there is no cure. Researchers at Rensselaer Polytechnic Institute have developed a...

Early warning sign of dementia may be missed in women because they perform better at memory tests
Up to 10% of women pass tests for cognitive impairment when they should not This is important because cognitive impairment frequently leads to dementia If not picked up early, medications and lifestyle changes may not work as well By VICTORIA ALLEN SCIENCE CORRESPONDENT FOR THE DAILY MAIL Memory problems may be missed in women because they perform better in certain tests than men. A study has found...

Function and Characteristics of Astrocytes in Disease and Development
Sponsored Content by Axol Bioscience Ltd Characteristics of Human Astrocytes Astrocytes, also known as astroglia, are characterized by their star-like shape and are the most abundant cell type in the brain. They have important roles in the blood-brain barrier function and in synaptic activity, and are closely linked to neurons. The study of astrocytes using in vitro co-culture models is becoming more important...

Does migraine leave your head spinning? Noninvasive treatment shows early promise
AMERICAN ACADEMY OF NEUROLOGY MINNEAPOLIS – There may be some good news for people with vestibular migraine, a type of migraine that causes vertigo and dizziness with or without headache pain. A small, preliminary study suggests that non-invasive nerve stimulation may show promise as a treatment for vestibular migraine attacks, a condition for which there...

Synchronized or independent neurons: This is how the brain encodes information
by International School of Advanced Studies (SISSA) “Like a book in which the single pages are not all different but carry small portions of common text, or like a group of people who whistle a very similar tune”: this is how our brain cells work, say scientists. It is the phenomenon of “co-relation,” in which...
