A molecule that protects from neuronal disorders
Many neuronal disorders, including epilepsy, schizophrenia and lissencephaly - a form of mental retardation -, result from abnormal migration of nerve cells during the development of the brain. view more (2007-09-17)
Electronic chip, interacting with the brain, modifies pathways for controlling movement
Researchers at the University of Washington (UW) are working on an implantable electronic chip that may help establish new nerve connections in the part of the brain that controls movement. view more (2006-10-25)
Daytime light exposure dynamically enhances brain responses
Exposure to light is known to enhance both alertness and performance in humans, but little is understood regarding the neurological basis for these effects, especially those associated with daytime light exposure. view more (2006-08-22)
Brain changes in patients with migraine
Researchers from Harvard Medical School have found increased thickness of two areas of the brain cortex in people with migraine when compared to healthy controls. view more (2006-10-17)
Brain cells work differently than previously thought
Scientists know that information travels between brain cells along hairlike extensions called axons. For the first time, researchers have found that axons don't just transmit information - they can turn the signal up or down with the right stimulation. view more (2007-08-20)
Brain malfunction explains dehydration in elderly
As Australia faces another hot, dry summer, scientists from Melbourne's Howard Florey Institute have warned that elderly people are at risk of becoming dehydrated because their brains underestimate how much water they need to drink to rehydrate. view more (2007-12-18)
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)
Taking up music so you can hear
Anyone with an MP3 device -- just about every man, woman and child on the planet today, it seems -- has a notion of the majesty of music, of the primal place it holds in the human imagination. view more (2009-08-18)
Adult brain processes fractions 'effortlessly'
Although fractions are thought to be a difficult mathematical concept to learn, the adult brain encodes them automatically without conscious thought. view more (2009-04-08)
Researcher developing new method for hearing loss assessment
A Purdue University researcher is working on a new technique to diagnose hearing loss in a way that more accurately reflects real-world situations. view more (2007-09-07)
Cortical plasticity: it's time to get excited about inhibition
Research from Brandeis University published online this week in Nature offers new insight into how neural circuits are shaped by experience. The article provides new evidence for the mechanisms that affect the ability of the visual cortex to plastically rearrange itself following periods of visual deprivation. view more (2006-08-24)
Revealing the machinery underlying the 'plastic' juvenile brain
Among the central mysteries of neurobiology is what properties of the young brain enable it to so adeptly wire itself to adapt to experience—a quality known as plasticity. view more (2007-03-01)
Human cerebellum and cortex age in very different ways
Researchers have found that the two primary areas of the human brain appear to age in radically different ways: The cortex used in higher-level thought undergoes more extensive changes with age than the cerebellum, which regulates basic processes such as heartbeat, breathing and balance. view more (2005-08-02)
The Fancier the Cortex, the Smarter the Brain?
Why are some people smarter than others? In a new article in Current Directions in Psychological Science, a journal of the Association for Psychological Science, Eduardo Mercado III from the University at Buffalo, The State University of New York, describes how certain aspects of brain structure and function help determine how easily we learn new... view more...

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" neural activity. view more (2007-12-26)
When less attention improves behavior
new study conducted at the Centre for Studies and Research in Cognitive Neuroscience of the University of Bologna, and published by Elsevier in the February 2009 issue of Cortex shows that, in confabulating patients, memory accuracy improves when attentional resources are reduced. view more (2009-01-22)
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)
Two minutes of magnetic stimulation can change your brain for an hour
A couple of minutes is all it takes to 'knock out' bits of your brain for an hour, according to a new study by a University College London (UCL) team. The team have been working on ways to improve a method known as transcranial magnetic stimulation (TMS) and are now using their adapted version of TMS to investigate possible treatments for stroke... view more...

Common gene version optimizes thinking — but with a possible downside
Most people inherit a version of a gene that optimizes their brain's thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking, scientists at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have discovered. view more (2007-02-09)
Is sleep 'hard-wired' into the brain?
Falling asleep is usually thought of as something we can control ourselves as part of our behaviour patterns. In a new article in the December Journal of the Royal Society of Medicine, Dr Bidi Evans argues that waking and sleeping is actually controlled by a physical mechanism that is 'hard-wired' into the brain. She suggests that evidence from... view more... (2002-11-25)
