Brain's Motor Areas Can Directly Turn Down Hearing
2014-09-02 03:06:42

Duke University When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements. This interplay between movement and hearing also has a counterpart deep in the brain. Indeed, indirect evidence has long suggested that the brain's motor cortex, which controls movement, somehow influences the auditory cortex, which gives rise...

brain changes mathematics
2014-08-19 03:30:41

Erin Digitale, Stanford University School of Medicine As children learn basic arithmetic, they gradually switch from solving problems by counting on their fingers to pulling facts from memory. The shift comes more easily for some kids than for others, but no one knows why. Now, new brain-imaging research gives the first evidence drawn from a longitudinal study to explain how the brain reorganizes itself as children learn math facts. A precisely orchestrated group of brain changes, many...

April Flowers for redOrbit.com - Your Universe Online Last night you couldn't get to sleep until the wee hours, and today you can't seem to concentrate on anything. You know the two are related, but how? A new study led by NYU Langone Medical Center and funded by the National Institutes of Health (NIH) has found that just a few nerve cells in the brain may control the switch between internal thoughts and external distractions. The findings, published in Cell, may represent a breakthrough...

3d brain tissue
2014-08-12 05:03:27

redOrbit Staff & Wire Reports - Your Universe Online A team of bioengineers from Tufts University in Massachusetts have developed three-dimensional brain-like cortical tissue that is similar in structure and function to tissues found in the brain of a rat, exhibits biochemical and electrophysiological responses, and can be kept alive in the laboratory for more than eight weeks. In research published in the August 11 early online edition of the journal Proceedings of the National...

sight and sound in the visual cortex
2014-05-26 04:33:05

redOrbit Staff & Wire Reports - Your Universe Online While analyzing the brain processes associated with sight, researchers from the University of Glasgow have discovered that the visual cortex processes information not just from the eyes, but from the ears as well. Writing in the journal Current Biology, the study authors explain that the auditory input makes it possible for a person’s visual system to predict incoming information, thus giving them an advantage in potentially...

Scientists Hunt Down Origin Of Huntington's Disease In The Brain
2014-04-29 17:24:09

Elaine Schmidt, University of California - Los Angeles Health Sciences The gene mutation that causes Huntington's disease appears in every cell in the body, yet kills only two types of brain cells. Why? UCLA scientists used a unique approach to switch the gene off in individual brain regions and zero in on those that play a role in causing the disease in mice. Published in the April 28 online edition of Nature Medicine, the research sheds light on where Huntington's starts in the...

The Prenatal Origins Of Autism In The Developing Brain
2014-03-28 07:48:58

Rebekah Eliason for redOrbit.com - Your Universe Online A new study from the University of California, San Diego School of Medicine and the Allen Institute for Brain Science provides evidence that the development of autism begins during pregnancy. For this study, 25 genes in the post-mortem brain tissue of children both with autism and without were analyzed. Researchers included Eric Courchesne, PhD, professor of neurosciences and director of the Autism Center of Excellence at UC San...

Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act. Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests — snack,...

Males Differ From Females In Specific Brain Structures
2014-02-12 13:09:03

University of Cambridge Reviewing over 20 years of neuroscience research into sex differences in brain structure, a Cambridge University team has conducted the first meta-analysis of the evidence, published this week in the prestigious journal Neuroscience and Biobehavioral Reviews. The team, led by doctoral candidate Amber Ruigrok and Professors John Suckling and Simon Baron-Cohen in the Department of Psychiatry, performed a quantitative review of the brain imaging literature testing...

Genetic Variation Linked To Intellectual Ability
2014-02-12 04:19:25

Brett Smith for redOrbit.com - Your Universe Online Previous research studies have demonstrated that the thickness of the cerebral cortex, or “cortical thickness,” is closely related to intellectual ability, and a new study from scientists at King's College London has revealed a gene related to both cortical thickness and intelligence . Published in the journal Molecular Psychiatry, the new study could help reveal the biological mechanisms behind some forms of intellectual...

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...
