How Our Brains Keep Us Focused

In a new study to appear in Neuron, scientists at the RIKEN Brain Science Institute (BSI) have uncovered mechanisms that help our brain to focus by efficiently routing only relevant information to perceptual brain regions. The results provide valuable insights on how our brains achieve such focus and on how this focus can be disrupted, suggesting new ways of presenting information that augment the brain's natural focal capabilities.

Focus on what I am about to tell you! Our complex modern world is filled with so many distractions - flashing images on a television screen, blinking lights, blaring horns - that our ability to concentrate on one thing at a time is of critical importance. How does our brain achieve this ability to focus attention?

fMRI Reveals Functional Brain Pathways Disrupted In Children With ADHD

Using functional magnetic resonance imaging (fMRI), researchers have identified abnormalities in the brains of children with attention deficit/hyperactivity disorder (ADHD) that may serve as a biomarker for the disorder, according to a study presented at the annual meeting of the Radiological Society of North America (RSNA).

ADHD is one of the most common childhood disorders, affecting an estimated five to eight percent of school-aged children. Symptoms, which may continue into adulthood, include inattention, hyperactivity and impulsivity behaviors that are out of the normal range for a child's age and development.

Performance Linked To Changes In Human Brain Structure Function: Findings Explore Complexities Of How The Brain Learns, Stores, And Recalls Info

New research just released provides insight into one of neuroscience's most intriguing mysteries: how the human brain learns and remembers. These studies - involving topics as diverse as musical memory, "change blindness," and attention deficit hyperactivity disorder (ADHD) - illustrate the profound influence that specific changes in either the brain's structure, function, or both, can have on human behavior.

The research findings were presented at Neuroscience 2011, the Society for Neuroscience's annual meeting and the world's largest source of emerging news about brain science and health.

Specifically, the studies show that:
