UCSF Study Shows Digital Cognitive Training Improves Brain Function and Behavior for People with Schizophrenia People with schizophrenia who completed 80 hours of intensive, computerized cognitive training exercises were better able to perform complex tasks that required them to distinguish their internal thoughts from reality. As described in the journal Neuron on Feb. 22, 2012, a small clinical study conducted at the San Francisco VA Medical Center (SFVAMC) and the University of...

It´s Valentine´s Day, he forgot to bring flowers, and somehow that painfully sad look on her face is simply not registering in his mind.  Could be it´s a problem in his prefrontal cortex? Neuropsychology researchers at the Montreal Neurological Institute and Hospital — The Neuro, McGill University, have found that two areas of the prefrontal cortex (PFC) are critical for either detecting or distinguishing emotions from facial expressions.  People with damage...

Strategy for maximizing uncertain rewards shows in MRI, math models Life shrouds most choices in mystery. Some people inch toward a comfortable enough spot and stick close to that rewarding status quo. Out to dinner, they order the usual. Others consider their options systematically or randomly. But many choose to grapple with the uncertainty head on. "Explorers" order the special because they aren't sure they'll like it. It's a strategy of maximizing rewards by discovering whether as yet...

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...

In the classic film "12 Angry Men," Henry Fonda's character sways a jury with his quiet, persistent intelligence. But would he have succeeded if he had allowed himself to fall sway to the social dynamics of that jury? Research led by scientists at the Virginia Tech Carilion Research Institute found that small-group dynamics -- such as jury deliberations, collective bargaining sessions, and cocktail parties -- can alter the expression of IQ in some susceptible people. "You may joke about...

Brain circuits for visual categorization revealed by new experiments Hundreds of times during a baseball game, the home plate umpire must instantaneously categorize a fast-moving pitch as a ball or a strike. In new research from the University of Chicago, scientists have pinpointed an area in the brain where these kinds of visual categories are encoded. While monkeys played a computer game in which they had to quickly determine the category of a moving visual stimulus, neural recordings...

Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation of long-term memories. The findings, published today [13 Dec] in the...

Major depressive disorder (MDD) is a severely debilitating illness characterized by sadness and an inability to cope. Not only does it affect a person's ability to concentrate and make decisions, it also alters their ability to experience pleasurable emotion, and instead prolongs negative thoughts and feelings. New research published in BioMed Central's open access journal Biology of Mood & Anxiety Disorders used functional magnetic resonance imaging (fMRI) to show aberrant connectivity...

Primates learn from feedback that surprises them, and in a recent investigation of how that happens, neurosurgeons have learned something new. The insight they gleaned from examining the response of specific brain tissues during a learning task may inform future rehabilitative therapies after stroke or traumatic brain injury. "It's been known for a long time that it's unexpected events in particular that drive learning," said Wael Asaad, assistant professor of neurosurgery in the Warren...

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...


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.
