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 inhibiting hunger and promoting feelings of being full. view more (2007-10-30)
First evidence that musical training affects brain development in young children
Researchers have found the first evidence that young children who take music lessons show different brain development and improved memory over the course of a year compared to children who do not receive musical training. view more (2006-09-20)
An amnesic patient with an extraordinary distorted memory
If somebody asks you "Do you remember what you did on March 13, 1985?" you are very likely to answer "I don't know", even if your memory is excellent. view more (2009-05-14)
Dolphins maintain round-the-clock visual vigilance
Dolphins have a clever trick for overcoming sleep deprivation. Sam Ridgway from the US Navy Marine Mammal Program explains that they are able to send half of their brains to sleep while the other half remains conscious. view more (2009-05-01)
Deafness and seizures result when mysterious protein deleted in mice
Scientists have discovered that mice genetically engineered to lack a particular protein in the brain have profound deafness and seizures. The finding suggests a pathway, they say, for exploring the hereditary causes of deafness and epilepsy in humans. view more (2008-01-25)
Stress disrupts human thinking, but the brain can bounce back
A new neuroimaging study on stressed-out students suggests that male humans, like male rats, don't do their most agile thinking under stress. The findings, published this month in the Proceedings of the National Academy of Sciences, show that 20 male M.D. candidates in the middle of preparing for their board exams had a harder time shifting their... view more...

MU Researchers Use Computational Models to Study Fear
The brain is a complex system made of billions of neurons and thousands of connections that relate to every human feeling, including one of the strongest emotions, fear. view more (2009-10-01)
Neuroscientists discover long-term potentiation in the olfactory bulb
Ben W. Strowbridge, Ph.D, associate professor of Neuroscience and Physiology/Biophysics, and Yuan Gao, a Ph.D. student in the neurosciences program at Case Western Reserve University School of Medicine, are the first to discover a form of synaptic memory in the olfactory bulb, the part of the brain that processes the sense of smell. view more (2009-05-04)
Not just your imagination: The brain perceives optical illusions as real motion
Ever get a little motion sick from an illusion graphic designed to look like it's moving? A new study suggests that these illusions do more than trick the eye; they may also convince the brain that the graphic is actually moving. view more (2009-02-03)
Brown Scientists Explain Inception of Perception in the Brain
The taste of champagne, the sound of a train, the flash of a pop fly into left field - indeed all of human perception - begins in the brain's center. That's where sensory information passes from the thalamus to the neocortex for processing. view more (2007-03-06)
A dynamical systems hypothesis of schizophrenia
The inconsistent expressions related to schizophrenia are newly structured in a recent study by researchers at the Universitas Pompeau Fabra (Barcelona), and Oxford University. view more (2007-11-09)
Emotional memories can be suppressed with practice, new CU-Boulder study says
A new University of Colorado at Boulder study shows people have the ability to suppress emotional memories with practice, which has implications for those suffering from conditions ranging from post-traumatic stress disorder to depression. view more (2007-07-13)
Columbia researchers identify early brain marker for familial form of depression
Findings from one of the largest-ever imaging studies of depression indicate that a structural difference in the brain - a thinning of the right hemisphere - appears to be linked to a higher risk for depression, according to new research at Columbia University Medical Center and the New York State Psychiatric Institute. view more (2009-03-24)
Research may unlock mystery of autism's origin in the brain
In the first study of its kind, researchers have discovered that in autistic individuals, connections between brain cells may be deficient within single regions, and not just between regions, as was previously believed. view more (2007-08-23)

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning
Using advanced brain imaging techniques, researchers at Georgetown University Medical Center have watched how humans use both lower and higher brain processes to learn novel tasks, an advance they say may help speed up the teaching of new skills as well as offer strategies to retrain people with perceptual deficits due to autism. view more (2007-03-15)
Penn researchers report that gene therapy awakens the brain despite blindness from birth
Researchers at the University of Pennsylvania have demonstrated that gene therapy used to restore retinal activity to the blind also restores function to the brain's visual center, a critical component of seeing. view more (2007-06-26)
'Word-vision' brain area confirmed
Humans have an uncanny ability to skim through text, instantly recognizing words by their shape-even though writing developed only about 6000 years ago-long after humans evolved. view more (2006-04-20)
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)
Short Stressful Events May Improve Working Memory
Experiencing chronic stress day after day can produce wear and tear on the body physically and mentally, and can have a detrimental effect on learning and emotion. However, acute stress -- a short stressful incident -- may enhance learning and memory. view more (2009-07-24)
