Brain Similarities In Humans And Monkeys
2014-01-29 04:46:02

April Flowers for redOrbit.com - Your Universe Online A new study from Oxford University researchers suggests a surprising degree of similarity in the organization of brain regions that control language and complex thought processes in humans and monkeys, as well as key differences. The team's finding demonstrate valuable insights into the evolutionary processes that established the link between humans and other primates and what made humans distinctly different. "We tend to think that...

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...

Specific area of the brain linked to anxiety disorders in youth Anxiety disorders are common in children and adolescents, affecting up to 25 percent of the youth population. Anxiety causes distress and functional impairment and, if left untreated, can result in bad grades, problems at home and increased rates of psychiatric disorders in adulthood. These risks constitute a significant public health burden, and they underscore the importance of continued efforts to understand the cause...

Non-motor symptoms, including abnormalities in cognition, mental behaviors, autonomic nerves and sensory perception, have the greatest effect on the quality of in Parkinson's disease patient life. Voxel-based morphometry can be used to quantitatively compare structural differences and func-tional changes of gray matter in subjects. According to a study, Gray matter images of 32 Parkinson's disease patients and 25 healthy controls were compared using voxel-based morphometry to investigate the...

In a breakthrough for understanding brain evolution, neuroscientists have shown that differences between primate brains - from the tiny marmoset to human – can be largely explained as consequences of the same genetic program. In research published in the Journal of Neuroscience, Professor Marcello Rosa and his team at Monash University's School of Biomedical Sciences and colleagues at Universidade Federal do Rio de Janeiro, in Brazil, used computer modelling to demonstrate that the...

Socialness In Carnivores Linked To Size Of Frontal Cortex
2013-10-09 05:49:36

April Flowers for redOrbit.com - Your Universe Online A growing body of research from Michigan State University reveals that the region of the brain that makes humans and primates social creatures may play a similar role in carnivores. Sharleen Sakai, professor of neuroscience, has studied spotted hyenas, lions, and most recently the raccoon family to find a correlation between the size of the animals' frontal cortex and their social nature. The current study, published in the journal...

Trying to explain riding a bike is difficult because it is an implicit memory. The body knows what to do, but thinking about the process can often interfere. So why is it that under certain circumstances paying full attention and trying hard can actually impede performance? A new UC Santa Barbara study, published today in the Journal of Neuroscience, reveals part of the answer. There are two kinds of memory: implicit, a form of long-term memory not requiring conscious thought and expressed...

Mental Illness Gene Treatment Schizophrenia
2013-07-16 09:13:45

Rebekah Eliason for redOrbit.com - Your Universe Online A new study involving brain impaired mice has the potential to improve therapy for people suffering from schizophrenia and major depressive disorder. While further research is necessary, this discovery is already being heralded as a major step toward understanding a variety of mental illnesses. The brain's prefrontal cortex, located in the anterior section of the frontal lobes, is associated with executive functions that help...

Frontal Lobe May Not Be Key To Intelligence After All
2013-05-14 08:56:44

redOrbit Staff & Wire Reports - Your Universe Online The frontal lobes are not disproportionately larger compared to other regions of the brain, suggesting other areas of the brain may play a role in humans´ unique cognitive abilities, according to new research published Monday in the Proceedings of the National Academy of Sciences (PNAS). Researchers from Durham University and Reading University compared the size of the frontal lobes — regions of a...


Word of the Day
monteith
  • A large punch-bowl of the eighteenth century, usually of silver and with a movable rim, and decorated with flutings and a scalloped edge. It was also used for cooling and carrying wine-glasses.
  • A kind of cotton handkerchief having white spots on a colored ground, the spots being produced by a chemical which discharges the color.
This word is possibly named after Monteith (Monteigh), 'an eccentric 17th-century Scotsman who wore a cloak scalloped at the hem.'
