Auditory neurons in humans far more sensitive to fine sound frequencies than most mammals
The human ear is exquisitely tuned to discern different sound frequencies, whether such tones are high or low, near or far. But the ability of our ears pales in comparison to the remarkable knack of single neurons in the brain to distinguish between the very subtlest of sound frequencies. view more (2008-01-11)
Anemia affects body ... and maybe the mind
For older adults, anemia's trademark loss of oxygen-toting red blood cells has long been linked to fatigue, muscle weakness and other physical ailments. view more (2006-09-14)
Study charts origins of fear
A team of researchers led by the University of Toronto has charted how and where a painful event becomes permanently etched in the brain - a discovery that has implications for pain-related emotional disorders such as anxiety and post-traumatic stress. view more (2005-09-16)
UI study reveals second pathway to feeling your heartbeat
A new study suggests that the inner sense of our cardiovascular state, our "interoceptive awareness" of the heart pounding, relies on two independent pathways, contrary to what had been asserted by prominent researchers. view more (2009-11-03)
Brains response to visual stimuli helps us to focus on what we should see, rather than all there is to see
Delving ever deeper into the intricate architecture of the brain, researchers at The Salk Institute have now described how two different types of nerve cells, called neurons, work together in tiny sub-networks to pass on just the right amount and the right kind of sensory information. view more (2005-10-24)
Brain imaging can predict effectiveness of cognitive behavior therapy for treating depression
Whether or not cognitive behavior therapy (CBT) will help a person recover from depression can be predicted through brain imaging. view more (2006-04-03)
Babies see it coming
Do infants only start to crawl once they are physically able to see danger coming? Or is it that because they are more mobile, they develop the ability to sense looming danger? view more (2009-09-24)
Penn Researchers Pinpoint the Brain Waves That Distinguish False Memories From Real Ones
For the first time, researchers at the University of Pennsylvania are able to pinpoint brain waves that distinguish true from false memories, providing a better understanding of how memory works and creating a new strategy to help epilepsy patients retain cognitive function. view more (2007-10-24)
Brain structure associated with fear inhibition also may influence personality
The relationship between the size of a brain structure and the ability to recover from traumatic experiences also may influence overall personality type. view more (2005-11-28)
Decoding short-term memory with fMRI
People voluntarily pick what information they store in short-term memory. Now, using functional magnetic resonance imaging (fMRI), researchers can see just what information people are holding in memory based only on patterns of activity in the brain. view more (2009-02-23)
Neural bottleneck found that thwarts multi-tasking
Many people think they can safely drive while talking on their cell phones. Vanderbilt neuroscientists Paul E. Dux and René Marois have found that when it comes to handling two things at once, your brain, while fast, isn't that fast. view more (2007-01-19)
A frown or a smile? Children with autism can't discern
When we have a conversation with someone, we not only hear what they say, we see what they say. Eyes can smolder or twinkle. Gazes can be direct or shifty. "Reading" these facial expressions gives context and meaning to the words we hear. view more (2007-05-07)
Wired for sound: How the brain senses visual illusions
In a study that could help reveal how illusions are produced in the brain's visual cortex, researchers at the UCSD School of Medicine have found new evidence of rapid integration of auditory and visual sensations in the brain. view more (2007-04-12)
Preclinical work shows how one gene causes severe mental retardation
Researchers at Duke University Medical Center and the University of North Carolina have discovered in mice how a single disrupted gene can cause a form of severe mental retardation known as Angelman syndrome. view more (2009-05-11)
Memory uses separate information pathways
The researchers studied two signals from different sensory parts of the brain, one of which arrived at the perirhinal and the other at the postrhinal cerebral cortex. These parts of the brain are located close to the sulcus and receive information from areas of the brain which process different types of sensory information. The information enters... view more...

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)
Do you hear what i see?
New research pinpoints specific areas in sound processing centers in the brains of macaque monkeys that shows enhanced activity when the animals watch a video. view more (2007-02-21)
Brain's 'hate circuit' identified
People who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit', according to new research by scientists at UCL (University College London). view more (2008-10-29)
Use science to convince teens a sober prom is better, AAAS says
This is the time of year when even teens who have never tried a drop of alcohol may be tempted. Middle and high school proms and graduation are big events and there will be multiple parties to attend and a wide array of opportunities for alcohol to be served. view more (2009-05-21)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
