The willingness of people to punish others who lie, cheat, steal or violate other social norms even when they weren´t harmed and don´t stand to benefit personally, is a distinctly human behavior. There is scant evidence that other animals, even other primates, behave in this “I punish you because you harmed him” fashion. Although this behavior — called third-party punishment — has long been institutionalized in human legal systems and economists have...

The part of the brain we use when engaging in egalitarian behavior may also be linked to a larger sense of morality, researchers have found. Their conclusions, which offer scientific support for Adam Smith's theories of morality, are based on experimental research published in the latest issue of the Proceedings of the National Academy of Sciences. The study, coming seven months after the start of the Occupy Wall Street Movement, which has been aimed at addressing income inequality, was...

Individuals with major depressive disorder (MDD) often undergo multiple courses of antidepressant treatment during their lives. This is because the disorder can recur despite treatment and because finding the right medication for a specific individual can take time. While the relationship between prior treatment and the brain's response to subsequent treatment is unknown, a new study by UCLA researchers suggests that how the brain responds to antidepressant medication may be influenced by...

(Ivanhoe Newswire) — Autism is a highly heritable neurodevelopmental disorder, yet the genetic underpinnings in the brain at young ages have remained largely unknown. But for the first time, researchers have identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder Until now, few studies have been able to investigate whole-genome gene expression and genotype variation in the brains of young patients...

Genetic studies find dysregulation in pathways that govern development of the prefrontal cortex in young patients with autism A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets...

(Ivanhoe Newswire) -- My toy, my snack, my juice box, kids can be selfish! A new study suggests that age-associated improvements in the ability to consider others are linked with maturation of the brain region involved in self control. The study may help to explain why children can be selfish when they are taught better and could improve educational strategies that are designed to encourage successful social behavior. Social interactions involve two parties who want the greatest possible...

(Ivanhoe Newswire) — Stress is a term commonly used today, and we know it can have an impact on one´s mental and physical well-being. Now researchers are saying it may affect your memory too! New research out of State University in New York, uncovered a neural mechanism that directly links repeated stress with impaired memory. Stress hormones are known to influence the prefrontal cortex (PFC), a brain region that controls high level "executive" functions such as working memory...

Neuron paper by UB researchers reveals why chronic stress in adolescence impairs memory, may trigger mental illness Chronic stress has a more powerful effect on the brain during adolescence than in adulthood and now there's proof at the molecular level. "We have identified a causal link between molecules and behaviors involved in stress responses," says Zhen Yan, PhD, a professor in the Department of Physiology and Biophysics in the UB School of Medicine and Biomedical Sciences. "It's...

A new study suggests that age-associated improvements in the ability to consider the preferences of others are linked with maturation of a brain region involved in self control. The findings may help to explain why young children often struggle to control selfish impulses, even when they know better, and could impact educational strategies designed to promote successful social behavior. Human social interactions often involve two parties who want to maximize their own outcomes while...


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.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
