Poverty may have direct implications for important, early steps in the development of the brain, saddling children of low-income families with slower rates of growth in two key brain structures, according to researchers from the University of Wisconsin–Madison. By age 4, children in families living with incomes under 200 percent of the federal poverty line have less gray matter — brain tissue critical for processing of information and execution of actions — than kids growing up in...

UAlberta medical researchers examine brain development of FASD participants as they age Medical researchers at the University of Alberta recently published findings showing that brain development is delayed throughout childhood and adolescence for people born with Fetal Alcohol Spectrum Disorder (FASD). Christian Beaulieu and Carmen Rasmussen, the two primary investigators in the research study, recently published the results of their work in the peer-reviewed journal, The Journal of...

Bigger Brains Indicate Hobbit Humans Evolved From Homo Erectus

Lawrence LeBlond for redOrbit.com - Your Universe Online The hobbit human, a small-statured race that evolved separately from our own ancestor Homo erectus on an island of the Indonesian Archipelago some 50,000 years ago, has been discovered by Japanese scientists to have a bigger brain than once believed. Hobbit humans, named after the tiny folk from JRR Tolkein's novels, are collectively known as Homo floresiensis (Man of Flores). The remains of the ancient humans were discovered on...

-A new study examined what brain volume recovery may take place during the first 14 days of abstinence from alcohol. -Findings indicate that recovery of cerebral gray matter volume can begin for alcoholic patients after only a few days of detoxification. -Recovery may vary among brain regions. Chronic alcohol abuse can severely damage the nervous system, particularly cognitive functions, cerebral metabolism, and brain morphology. Building upon previous findings that alcoholics can...

An Evolutionary Biologist at The University of Manchester, working with scientists in the United States, has found compelling evidence that parts of the brain can evolve independently from each other. It's hoped the findings will significantly advance our understanding of the brain. The unique 15 year study with researchers at the University of Tennessee and Harvard Medical School also identified several genetic loci that control the size of different brain parts. The aim of the...

(Ivanhoe Newswire) -- Scientists using magnetic resonance imaging (MRI) observed that the brains of children with autism spectrum disorder are larger than those without autism, but this difference appears related to increased rates of brain growth before 2 years of age. Autism researchers have long known of the connection between the developmental disorder and an increase in brain size, although the cause and timing are not well defined. "The timing of brain enlargement in autism is of...

Whether cognitive differences exist between modern humans and Neanderthals is the subject of contentious disputes in anthropology and archaeology. Because the brain size range of modern humans and Neanderthals overlap, many researchers previously assumed that the cognitive capabilities of these two species were similar. Among humans, however, the internal organization of the brain is more important for cognitive abilities than its absolute size is. The brain's internal organization depends on...

The brains of newborn humans and Neanderthals are about the same size and appear rather similar overall. It's mainly after birth, and specifically in the first year of life, that the differences between our brains and those of our extinct relatives really take shape, according to a report published in the Nov. 9 issue of Current Biology, a Cell Press publication. The findings are based on comparisons of virtual imprints of the developing brain and surrounding structures (known as endocasts)...

 For the past 2 million years, the size of the human brain has tripled, growing much faster than other mammals. Examining the reasons for human brain expansion, University of Missouri researchers studied three common hypotheses for brain growth: climate change, ecological demands and social competition. The team found that social competition is the major cause of increased cranial capacity.To test the three hypotheses, MU researchers collected data from 153 hominid (humans and our...

Packs of hunting dogs, troops of baboons, herds of antelope: when people observe social animals, they are often struck by how intelligent they seem, and recent studies suggest that sociality has played a key role in the evolution of larger brain size among several orders of mammals. But new research from two evolutionary biologists, John Finarelli of the University of Michigan and John Flynn of the American Museum of Natural History, calls this hypothesis into question"”at least for the...

baudekin
  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
