Can measure human intelligence?
Researchers at Washington University in St. Louis (USA) determined the factors that make a person more intelligent than another. According to the study, published in the Journal of Neuroscience, the high level of activity neuronal connections in the lateral prefrontal cortex of the brain, is one of the main signs that a person is smarter than another.
Other studies have shown that this brain area, located beneath the temple, plays a key role in the high-level mental processing, as they produce complex cognitive functions, decision-making, coordinating thoughts, goals, actions and purposes.
Smart Tasks
The study consisted of subjecting participants to functional magnetic resonance imaging (fMRI) while resting passively. Following this, the volunteers performed various tasks for measuring intelligence, which were based on their ability to think quickly and use abstract thinking, as well as cognitive control tasks to calculate the levels of brain connectivity.
Find a potential negative effect of excessive brain of violent video games
An analysis of functional magnetic resonance imaging, performed in the brain to detect possible long-term effects of playing violent video games for many hours, has revealed temporal changes in brain regions associated with cognitive functions and control of emotions in young adults after a week to devote several hours to play with a game of this type.
The controversy over whether or not violent video games are potentially harmful to users is in the spotlight for many years. However, there is little scientific evidence to demonstrate unequivocally that video games of this kind have prolonged negative neurological effects.
The effects of winning or losing is felt almost everywhere in the brain
The human brain devotes significant resources to the results of games where you win or lose, and similar situations, suggests a new study.
This study shows that during a game, almost the entire brain in each participant is involved, not just the reward centers of the scientific community that they have been attributing the leading role in shaping human behavior adaptive.
Speaking and understanding speech share the same parts of the brain
The brain has two main tasks associated with the sonic language: speaking, and understand what others are talking. For a long time, psychologists and other students of the brain have been debating whether these tasks required of two very different types of activity, or whether, on the contrary, both used the same regions of the brain.
Now, a new study seems to have found the definitive answer. The team of Menenti Laura (University of Glasgow, UK), Peter Hagoort (Radboud University Nijmegen, Netherlands), and Sarah Gierhan and Katrien Segaert (Max Planck Institute for Psycholinguistics, also in the Netherlands), technology used functional magnetic resonance imaging (fMRI) to measure brain activity in people who were listening or saying phrases.
Best Analysis of Dyslexia
Certain brain scans might be able to predict which children with dyslexia are likely to improve their reading skills over time. This is the conclusion reached in a new study.
Many children suffer from dyslexia, a learning disorder that makes it difficult to read. In the United States are estimated to represent between 5 and 17 percent of the children.
Many dyslexic children are able to make significant improvements in their reading skills, but it is not clear how they do it, and standardized reading tests can not predict which children are likely to improve reading skills.
If larger studies confirm the findings from recent research by a team of experts led by specialists from MIT and Stanford University could be used brain scans using functional magnetic resonance imaging (fMRI) as a tool for predict improvements in reading in dyslexic children. John Gabrieli, a professor of brain and cognitive sciences at MIT, believes that the scans of that class may also help scientists and educators to develop new teaching methods that harness the brain pathways that dyslexic children seem to use to compensate for their problem. These strategies might help dyslexic children regardless of brain patterns exhibited.
