Research shows morally laden scenarios get different responses from people of different ages.Moral responses change as people age says a new study from the University of Chicago.Both preschool children and adults distinguish between damage done either intentionally or accidently when assessing whether a perpetrator has done something wrong, said study author Jean Decety. But, adults are much less likely than children to think someone should be punished for damaging an object, for example,...

A University of Toronto study shows that when formerly depressed people experience mild states of sadness, their brain's response can predict if they will become depressed again. "Part of what makes depression such a devastating disease is the high rate of relapse," says Norman Farb, a PhD psychology student and lead author of the study. "However, the fact that some patients are able to fully maintain their recovery suggests the possibility that different responses to the type of emotional...

Researchers at Mount Sinai School of Medicine have published new data on why the aging brain is less resilient and less capable of learning from life experiences. The findings provide further insight into the cognitive decline associated with aging and neurodegenerative diseases like Alzheimer's. The study is published in the May 25 issue of the Journal of Neuroscience. The Mount Sinai team evaluated the prefrontal cortex"”the part of the brain that controls a wide range of cognitive...

A new study from Karolinska Institutet in Sweden shows that the brain has built-in mechanisms that trigger an automatic reaction to someone who refuses to share. The reaction derives from the amygdala, an older part of the brain. The subjects' sense of justice was challenged in a two-player money-based fairness game, while their brain activity was registered by an MR scanner. When bidders made unfair suggestions as to how to share the money, they were often punished by their partners even if...

Study highlights the importance of cognitive skills in exercising control over addictive drugs A study, completed by researchers from Trinity College and the Research Institute for a Tobacco Free Society, Dublin, Ireland, compares former smokers to current smokers, and obtains insight into how to quit smoking might be discovered by studying the brains of those who have successfully managed to do so. Functional MRI images were obtained while current smokers, former smokers and never smokers...

With certain variations people will stick longer with instructions that contradict experience Researchers at Brown University have found that specific genetic variations can predict how persistently people will believe advice they are given, even when it is contradicted by experience. The story they tell in a paper in the April 20 issue of the Journal of Neuroscience is one of the byplay between two brain regions that have different takes on how incoming information should influence thinking....

Drugs like marijuana act on naturally occurring receptors in the brain called cannabinoid receptors. However, the mechanisms by which these drugs produce their sensory and mood altering effects within the brain are largely unknown. Research led by Steven Laviolette at The University of Western Ontario has now identified a critical brain pathway responsible for the effects of cannabinoid drugs on how the brain processes emotional information. The findings, published in The Journal of...

By Yasmin Anwar, University of California, Berkeley A sleepless night can make us cranky and moody. But a lesser known side effect of sleep deprivation is short-term euphoria, which can potentially lead to poor judgment and addictive behavior, according to new research from the University of California, Berkeley. Researchers at UC Berkeley and Harvard Medical School studied the brains of healthy young adults and found that their pleasure circuitry got a big boost after a missed night's sleep....

New study reveals that 'categorical' information is processed by the right hemisphere Consider the simple situation in which you are walking around the kitchen and decide to pick up your own cup of tea, which is identical to others lying on the table. Your brain chooses the correct cup of tea by using different types of information that you have stored about the position of the cup in relation to the kitchen table. The information can be represented in qualitative terms (left, right, above,...

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
Cthulhu
  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
