Neurons for numerosity: Parietal neurons 'sum up' individual items in a group
As any child knows, to answer the question "how many," one must start by adding up individual objects in a group.   view more (2007-07-24)

Everything in its place: Researchers identify brain cells used to categorize images
Socks in the sock drawer, shirts in the shirt drawer, the time-honored lessons of helping organize one's clothes learned in youth. But what parts of the brain are used to encode such categories as socks, shirts or any other item, and how does such learning take place?   view more (2006-08-28)

QBI scientist looks at why stroke causes vision problems
The research, by QBI neuroscientist Professor Jason Mattingley and colleagues at the University of Melbourne and University College London, has implications for understanding "spatial neglect", a disorder associated with damage to the brain's parietal lobe - an area that plays an... view more (2007-06-07)

Brain imaging and genetic studies link thinking patterns to addiction
Scientists have for the first time identified brain sites that fire up more when people make impulsive decisions. In a study comparing brain activity of sober alcoholics and non-addicted people making financial decisions, the group of sober alcoholics showed significantly more "impulsive"... view more (2007-12-26)

Cognitive, genetic clues identified in imaging study of alcohol addiction
People with clinical addictions know first-hand the ravages the disease can take on almost every aspect of their lives. So why do they continue addictive behaviors, even after a period of peaceable abstinence"   view more (2007-12-26)

Neuroscientists searching for roots of empathy
In a pair of pioneering studies, a French (INSERM) and American team of social-cognitive neuroscientists have identified a network of brain regions that are involved in human imitation and specific brain areas that enable a person to distinguish the self from others. The research is part of a... view more (2002-01-23)

Studies yield insight into the numerical brain
Two studies in the January 18, 2007, issue of the journal Neuron, published by Cell Press, shed significant light on how the brain processes numerical information—both abstract quantities and their concrete representations as symbols.   view more (2007-01-18)

The root of dyscalculia found
Scientists led by UCL (University College London) have induced dyscalculia in subjects without the maths learning difficulty for the first time. The study, which finds that the right parietal lobe is responsible for dyscalculia, potentially has implications for diagnosis and management through... view more (2007-03-23)

Researchers gain insight into why brain areas fail to work together in autism
Researchers have found in two studies that autism may involve a lack of connections and coordination in separate areas of the brain.   view more (2006-07-13)

Gene variant is associated with brain anatomy, clinical course of ADHD
A variant of the dopamine receptor gene may be associated with attention-deficit/hyperactivity disorder (ADHD) and with thinner tissue in areas of the brain that handle attention, but also appears associated with better clinical outcomes among individuals with the disorder.   view more (2007-08-07)

Inhibitory systems control the pattern of activity in the cortex
Inhibitory systems are essential for controlling the pattern of activity in the cortex, which has important implications for the mechanisms of cortical operation, according to a Yale School of Medicine study in Neuron.   view more (2005-08-29)

Sound adds speed to visual perception
The traditional view of individual brain areas involved in perception of different sensory stimuli-i.e., one brain region involved in hearing and another involved in seeing-has been thrown into doubt in recent years.   view more (2008-08-12)

Blindsight: How brain sees what you do not see
Blindsight is a phenomenon in which patients with damage in the primary visual cortex of the brain can tell where an object is although they claim they cannot see it.   view more (2008-10-15)

When your memories can no longer be trusted
You went to a wedding yesterday. The service was beautiful, the food and drink flowed and there was dancing all night. But people tell you that you are in hospital, that you have been in hospital for weeks, and that you didn't go to a wedding yesterday at all.   view more (2008-05-29)

Brain studies reveal the mechanisms of the voluntary control of visual attention
Neuroscientists at Duke University have mapped the timing and sequence of neural activations that unfold in the brain when people focus their attention on specific locations in their visual fields.   view more (2007-01-04)

People Use Separate Brain Mechanisms to Make Ambiguous and Risky Choices
Distinct regions of the human brain are activated when people are faced with ambiguous choices versus choices involving only risk, Duke University Medical Center researchers have discovered.   view more (2006-03-06)

Selective attention increases both gain and feature selectivity of the human auditory cortex
On Sept. 19, a research report by Helsinki University of Technology, Laboratory of Computational Engineering scientists will appear in the online, open-access journal PLoS ONE, showing that selective attention increases both gain and feature selectivity of the human auditory cortex.   view more (2007-09-19)

Brain circuits that control hunger identified
Researchers at UCLA have determined the brain circuits involved in hunger that are influenced by a hormone called leptin. In previous clinical trials, supplementation of leptin, the signaling molecule produced by fat cells, produced moderate weight loss in some obese patients, purportedly by... view more (2007-10-30)

Social exclusion changes brain function and can lead to poor decision-making
Poor Bridget Jones. At the beginning of the first film about her diary and life, the character, played by actress Renée Zellweger, is fat and alone in her apartment where she mimes one of the great self-pitying song hits of all time: "All by Myself." But Bridget's problem may be... view more (2006-11-09)

Pular antidepressants boost brain growth, Hopkins scientists report
The beneficial effects of a widely used class of antidepressants might be the result of increased nerve-fiber growth in key parts of the brain, according to a Johns Hopkins study being published in the January 2006 issue of the Journal of Neurochemistry.   view more (2005-12-20)

Effects of preterm birth and early environmental risks continue into adolescence
In one of the first studies to use brain imaging with adolescents born prematurely, New Jersey researchers report that the effects of premature birth and environmental risks on the brain during the first three years of childhood continue through adolescence.   view more (2006-03-22)

Clues to the progression of Alzheimer's disease revealed in brain imaging studies
A novel imaging agent heralded for its potential to diagnose Alzheimer's disease during life is now giving researchers information never before available about how and where the disease progresses in the brain.   view more (2005-11-15)

Quicker and easier rehabilitation following a stroke
By artificially vibrating certain muscle parts, the brain areas and neuronal pathways responsible for movement can be trained. This has the potential to help stroke patients recover their mobility more quickly. These are the results of PhD research by Maarten Steyvers of the Department of... view more (2004-06-11)

Neuroscientist scans brain for clues on best time to multitask
In today's fast-paced world, multitasking has become an increasingly necessary part of our daily routine. Unfortunately, multitasking also is notoriously inefficient. However, a new brain imaging study led by a cognitive neuroscientist at the University of New Hampshire finds that there are optimal... view more (2008-09-03)
