Study Reveals Brain's Mysterious Switchboard Operator
2012-08-17 16:08:49

A mysterious region deep in the human brain could be where we sort through the onslaught of stimuli from the outside world and focus on the information most important to our behavior and survival, Princeton University researchers have found. The researchers report in the journal Science that an area of our brain called the pulvinar regulates communication between clusters of brain cells as our brain focuses on the people and objects that need our attention. Like a switchboard operator, the...

Brain Scans Can Assess Child’s Age
2012-08-17 10:33:52

Connie K. Ho for redOrbit.com — Your Universe Online A group of researchers, led by scientists from the University of California, San Diego (UCSD), have created a set of measurements that can measure a child´s age with 92 percent accuracy. The study´s results, published in the September 25 edition of Current Biology, highlighted the issue on biological variability in children. The researchers found that structural measures and maturational differences during adolescence...

Brain Power, Not Muscle Strength Related To Force Of Karate Punch
2012-08-16 12:29:05

Connie K. Ho for redOrbit.com — Your Universe Online Brain scans of karate experts recently showed distinctive features. Researchers believe that the images show how the ability to punch for black belts and karate novices could be related to a certain feature in the brain. The researchers, hailing from Imperial College London and University College London, discovered differences in the structure of the connection between brain regions, otherwise known as white matter. To begin,...

Scientists from The Scripps Research Institute have identified a new stem cell population that may be responsible for giving birth to the neurons responsible for higher thinking. The finding also paves the way for scientists to produce these neurons in culture–a first step in developing better treatments for cognitive disorders, such as schizophrenia and autism, which result from disrupted connections among these brain cells. Published in the August 10, 2012 issue of the journal...

Imaging Neural Pathways In Brain Show Intelligence Levels
2012-08-02 12:51:02

Connie K. Ho for redOrbit.com — Your Universe Online The brain is an intricate part of the body to say the least. And new research has focused on the effect of neural connectivity on one area of these intricacies, imaging a person's brain to estimate their level of intelligence. Researchers have long thought that overall brain size can affect individual variations in intelligence. A past study delved into this particular topic and demonstrated that the brain´s lateral...

Wayne State University School of Medicine researchers, working with colleagues in Canada, have found that one or more substances produced by a type of immune cell in people with multiple sclerosis (MS) may play a role in the disease's progression. The finding could lead to new targeted therapies for MS treatment. B cells, said Robert Lisak, M.D., professor of neurology at Wayne State and lead author of the study, are a subset of lymphocytes (a type of circulating white blood cell) that...

UCLA researchers say blocking this molecule may improve and speed recovery FINDINGS: Researchers at UCLA have identified a novel molecule in the brain that, after stroke, blocks the formation of new connections between neurons. As a result, it limits the brain's recovery. In a mouse model, the researchers showed that blocking this molecule–called ephrin-A5--induces axonal sprouting, that is, the growth of new connections between the brain's neurons, or cells, and as a result...

Several years ago, Prof. Michael Fainzilber and his group in the Biological Chemistry Department made a surprising discovery: Proteins thought to exist only near the cell nucleus could also be found in the far-off regions of the body's longest cells — peripheral nerve cells that extend processes called axons, reaching up to a meter in length in adult humans. These proteins, known as importins, have a well-studied role in the vicinity of the nucleus: They shuttle various molecules...

Neuroscientists from Wayne State University and the Massachusetts Institute of Technology (MIT) are taking a deeper look into how the brain mechanisms for memory retrieval differ between adults and children. While the memory systems are the same in many ways, the researchers have learned that crucial functions with relevance to learning and education differ. The team's findings were published on July 17, 2012, in the Journal of Neuroscience. According to lead author Noa Ofen, Ph.D.,...

Korean scientists have used tiny stars, squares and triangles as a toolkit to create live neural circuits in a dish. They hope the shapes can be used to create a reproducible neural circuit model that could be used for learning and memory studies as well as drug screening applications; the shapes could also be integrated into the latest neural tissue scaffolds to aid the regeneration of neurons at injured sites in the body, such as the spinal cord. Published today, 20 July, in IOP...

Midbrain
2013-07-25 15:13:23

The midbrain, also known as the mesencephalon is the part of the brain most responsible for vision, motor control, arousal, temperature regulation, alertness and hearing. Formation and Orientation The midbrain is found under the cerebral cortex and above the hindbrain. The mesencephalon is not divided into any other portions of the brain unlike the other two vesicles that stem from the neural tube. There are four separate lobes on the side of the cerebral aqueduct within the...

Brain
2013-03-05 13:54:00

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...

tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
