Smithsonian researchers report that the brains of tiny spiders are so large that they fill their body cavities and overflow into their legs. As part of ongoing research to understand how miniaturization affects brain size and behavior, researchers measured the central nervous systems of nine species of spiders, from rainforest giants to spiders smaller than the head of a pin. As the spiders get smaller, their brains get proportionally bigger, filling up more and more of their body cavities....

Multiple sclerosis (MS) may progress from the outermost layers of the brain to its deep parts, and isn't always an "inside-out" process as previously thought, reported a new collaborative study from researchers at the Mayo Clinic and the Cleveland Clinic. The traditional understanding is that the disease begins in the white matter that forms the bulk of the brain's inside, and extends to involve the brain's superficial layers, the cortex. Study findings support an opposite, outside-in...

Neuroimaging has provided fascinating insight into the dynamic nature of human brain maturation. However, most studies of developmental changes in brain anatomy have considered individual locations in relative isolation from all others and have not characterized relationships between structural changes in different parts of the developing brain. Now, new research describes the first comprehensive study of coordinated anatomical maturation within the developing human brain. The study,...

How the human brain and human cognitive abilities evolved in less than six million years has long puzzled scientists. A new study conducted by scientists in China and Germany, and published December 6 in the online, open-access journal PLoS Biology, now provides a possible explanation by showing that activity levels of genes in the human brain during development changed substantially compared to chimpanzees and macaques. What's more, these changes might be caused by a handful of key...

New Brain Study Illuminates Complexity of Linguistic Processing

While researchers have long known that the left hemisphere of the human brain is critical in the process of  producing and decoding semantics and language, the intricacies of the ℠division of labor´ between the different areas of the brain have largely remained a mystery. Technological advances in the field of brain imaging in the last decade, however, have begun to allow researchers to get a better look into the geography of the brain in these extremely complex cognitive...

Soccer 'Headers' Can Lead To Brain Injury

Soccer players beware: Doctors warn that ℠heading´ too many balls can lead to brain damage. That´s the message in a new study from researchers who persented their research at the annual meeting of the Radiological Society of North America. Using diffusion tensor imaging (DTI) to study the effects of soccer ℠heading,´ researchers have found that players who head the ball very frequently have brain abnormalities similar to those found in traumatic brain injury...

Recovery depends on the exchange of information between the brain hemispheres The structure of the corpus callosum, a thick band of nerve fibres that connects the two halves of the brain with each other and in this way enables the rapid exchange of information between the left and right hemispheres, plays an important role in the regaining of motor skills following a stroke. A study currently published in the journal Human Brain Mapping has shown that in stroke patients with particularly...

A new study using magnetic resonance imaging data of 406 adult human twins affirms the long-standing idea that the genetic basis of human cortical regionalization — the organization of the outer brain into specific functional areas — is similar to and consistent with patterns found in other mammals, indicating a common conservation mechanism in evolution. The findings by researchers at the University of California, San Diego School of Medicine and colleagues are published in...

The brain scans of high school football and hockey players showed subtle injury -- even if they did not suffer a concussion — after taking routine hits to the head during the normal course of play, according to a University of Rochester Medical Center study. The research, reported  online in the journal Magnetic Resonance Imaging, is preliminary, involving a small sample of athletes, but nonetheless raises powerful questions about the consequences of the mildest head injury...

Researchers at UCLA have found a possible explanation for why autistic children act and think differently than their peers. For the first time, they've shown that the connections between brain regions that are important for language and social skills grow much more slowly in boys with autism than in non-autistic children.   Reporting in the current online edition of the journal Human Brain Mapping, senior author Jennifer G. Levitt, a professor of psychiatry at the Semel Institute for...


Word of the Day
cenobite
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
