Strongly influenced by their self-interest, humans do not protest being overcompensated, even when there are no consequences, researchers in Georgia State University’s Brains and Behavior Program have found. Atlanta, GA (PRWEB) August 22, 2014 Strongly influenced by their self-interest, humans do not protest being overcompensated, even when there are no consequences, researchers in Georgia State University’s Brains and Behavior Program have found. This could imply that humans are less...

Rayshell Clapper for redOrbit.com - Your Universe Online People suffer from stress under a litany of situations. Some situations are temporarily stressful and then dissipate while others lead to long-term psychological problems including post-traumatic stress disorder (PTSD). It seems that more people these days suffer from the consequences of stress, which leads to many studies about the mental illness. In one study completed by Duke University, the study's senior author Dr. Kafui...

Elsevier The inability to ignore irrelevant stimuli underlies the impaired working memory and cognition often experienced by individuals diagnosed with schizophrenia, reports a new study in the current issue of Biological Psychiatry. Our brains are usually good at focusing on the information that we are trying to learn and filtering out the "noise" or thoughts that aren't relevant. However, memory impairment in schizophrenia may be related in part to a problem with this filtering...

A Link Found Between Musical Training And Executive Brain Function

Alan McStravick for redorbit.com - Your Universe online Musical training and performance programs like Suzuki Strings have long been thought to be beneficial to the child student though little, if any, research was able to substantively back up that assertion. With research recently conducted at Boston Children's Hospital, evidence now exists that shows just how beneficial early musical training can be in helping to determine an individual's later academic success and prolonged executive...

In life, many tasks have a context that dictates the right actions, so when people learn to do something new, they'll often infer cues of context and rules. In a new study, Brown University brain scientists took advantage of that tendency to track the emergence of such rule structures in the frontal cortex — even when such structure was not necessary or even helpful to learn — and to predict from EEG readings how people would apply them to learn new tasks speedily. Context and rule...

Keep this in mind: Scientists say they've learned how your brain plucks information out of working memory when you decide to act. Say you're a busy mom trying to wrap up a work call now that you've arrived home. While you converse on your Bluetooth headset, one kid begs for an unspecified snack, another asks where his homework project has gone, and just then an urgent e-mail from your boss buzzes the phone in your purse. During the call's last few minutes these urgent requests — snack,...

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...

A team of researchers at Inserm led by Cyril Herry (Inserm Unit 862, “Neurocentre Magendie,” Bordeaux) has just shown that interneurons located in the forebrain at the level of the prefrontal cortex are heavily involved in the control of fear responses. Using an approach combining in vivo recordings and optogenetic manipulations in mice, the researchers succeeded in showing that the inhibition of parvalbumin-expressing prefrontal interneurons triggers a chain reaction resulting in fear...

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...


Word of the Day
cock-a-hoop
  • Exultant; jubilant; triumphant; on the high horse.
  • Tipsy; slightly intoxicated.
This word may come from the phrase 'to set cock on hoop,' or 'to drink festively.' Its origin otherwise is unclear. A theory, according to the Word Detective, is that it's a 'transliteration of the French phrase 'coq a huppe,' meaning a rooster displaying its crest ('huppe') in a pose of proud defiance.' Therefore, 'cock-a-hoop' would 'liken a drunken man to a boastful and aggressive rooster.'
