Treatment of obstructive sleep apnea (OSA) in children normalizes disturbances in the neuronal network responsible for attention and executive function, according to a new study. "OSA is known to be associated with deficits in attention, cognition, and executive function," said lead author Ann Halbower, MD, Associate Professor at the Children's Hospital Sleep Center and University of Colorado Denver. "Our study is the first to show that treatment of OSA in children can reverse neuronal...

A study by a new member of the Medical Faculty of the University of Geneva and a group of American researchers opened a novel window on the neuronal circuits involved What happens at the level of individual neurons while we learn? This question intrigued the neuroscientist Daniel Huber, who recently arrived at the Department of Basic Neuroscience at the UNIGE. During his stay in the United States, he and his team tried to unravel the network mechanisms underlying learning and memory at the...

Multiple disease-related changes progress in parallel through distinct stages Studying a mouse model of Alzheimer's disease, neuroscientists at the Technische Universitaet Muenchen have observed correlations between increases in both soluble and plaque-forming beta-amyloid — a protein implicated in the disease process — and dysfunctional developments on several levels: individual cortical neurons, neuronal circuits, sensory cognition, and behavior. Their results, published in...

Breakdown of white-matter pathways affects decision-making as we age If you are an aging baby boomer and you've noticed it's a bit harder to drive to unfamiliar locations or to pick a new brand of olive oil at the supermarket, you can blame it on the white matter in your brain. A brain-mapping study, published in the Apr. 11 issue of The Journal of Neuroscience, has found that people's ability to make decisions in novel situations decreases with age and is associated with a reduction in...

Study published in Cell by Allen Institute for Brain Science examines cellular and molecular organization of human and mouse brain Scientists at the Allen Institute for Brain Science have identified similarities and differences among regions of the human brain, among the brains of human individuals, and between humans and mice by analyzing the expression of approximately 1,000 genes in the brain. The study, published online today in the journal Cell, sheds light on the human brain in...

Seeing Beyond The Visual Cortex

[ Watch the Video ] Research could lead to new rehabilitative therapies when visual cortex is damaged It's a chilling thought--losing the sense of sight because of severe injury or damage to the brain's visual cortex. But, is it possible to train a damaged or injured brain to "see" again after such a catastrophic injury? Yes, according to Tony Ro, a neuroscientist at the City College of New York, who is artificially recreating a condition called blindsight in his lab. "Blindsight...

The first atlas of the surface of the human brain based upon genetic information has been produced by a national team of scientists, led by researchers at the University of California, San Diego School of Medicine and the VA San Diego Healthcare System. The atlas reveals that the cerebral cortex — the sheet of neural tissue enveloping the brain — is roughly divided into genetic divisions that differ from other brain maps based on physiology or function. The genetic atlas...

If you are looking for a particular object – say a yellow pencil – on a cluttered desk, how does your brain work to visually locate it? For the first time, a team led by Carnegie Mellon University neuroscientists has identified how different neural regions communicate to determine what to visually pay attention to and what to ignore. This finding is a major discovery for visual cognition and will guide future research into visual and attention deficit disorders. The study,...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
