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...

Over the first few years of life, human cognition continues to develop, soaking up information and experiences from the environment and far surpassing the abilities of even our nearest primate relatives. In a study published online today in Genome Research, researchers have identified extended synaptic development in the human brain relative to other primates, a finding that sheds new light on the biology and evolution of human cognition. "Why can we absorb environmental information during...

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...

IQ Can Change Significantly During Teen Years

New research funded by the Wellcome Trust suggests that IQ scores in teenagers can dramatically change in conjunction with changes that occur in the brain, according to various media reports. IQ, the standard measure of intelligence, has been thought to remain stable across a person´s life, and childhood scores are often used to predict education outcome and job prospects as an adult. However, based on findings from the study, researchers caution using the 11+ exam for grammar school...

(Ivanhoe Newswire) -  Can human brain be “plastic”? According to the research funded by the Welcome Trust it can. Apparently, IQ, the standard measure of intelligence, can increase or fall significantly during teenage years.   Researchers at the Welcome Trust Centre for Neuroimaging at UCL (University College London) and the Centre for Educational Neuroscience discovered that our IQ is actually not constant and may change throughout our lifetime.   The research...

Researchers Find First Human From Primate Gene Split In Brain

A new analysis has found that the first genes which appeared after the primate branch split are more likely to be expressed in the developing human brain. Researchers believe that evolutionary recent genes may be responsible for constructing the uniquely powerful human brain. "We found that there is a correlation between new gene origination and the evolution of the brain," senior author Manyuan Long, PhD, Professor of Ecology & Evolution at the University of Chicago, wrote in the...

New research suggests the growth rate of the brain's cerebral cortex in babies born prematurely may predict how well they are able to think, speak, plan and pay attention later in childhood. The research is published in the October 12, 2011, online issue of Neurology, the medical journal of the American Academy of Neurology. The cerebral cortex is the outer layer of the brain covering the cerebrum, and is responsible for cognitive functions, such as language, memory, attention and thought....

(Ivanhoe Newswire) -- The bigger the better! New research shows that may be true when dealing with the brains of premature babies. The research suggests the growth rate of a premature baby's cerebral cortex may predict how well they are able to think, speak, plan and pay attention later in childhood. "The period before a full-term birth is critical for brain development. Problems occurring at this time have long-term consequences, and it appears that preterm birth affects brain growth,"...

Call a bird "birdbrained" and they may call "fowl." Cornell University researchers have proven that the capacity for learning in birds is not linked to overall brain size, but to the relative size and proportion of their specific brain regions. Songbirds with upper brain regions that are larger in relation to lower regions have a greater capacity for learning songs. Higher brain areas control the majority of cognitive and learning functions, while lower brain areas control more motor...

How well our brain functions is largely based on our family's genetic makeup, according to a University of Melbourne led study. The study published in the international publication The Journal of Neuroscience provides the first evidence of a genetic effect on how "Ëœcost-efficient' our brain network wiring is, shedding light on some of the brain's make up. Lead author Dr Alex Fornito from the Melbourne Neuropsychiatry Centre at the University of Melbourne said the findings have...


Word of the Day
grass-comber
  • A landsman who is making his first voyage at sea; a novice who enters naval service from rural life.
According to the OED, a grass-comber is also 'a sailor's term for one who has been a farm-labourer.'
