Research reveals molecular fingerprint of cocaine addiction
The first large-scale analysis of proteins in the brains of monkeys addicted to cocaine reveals new information on how long-term cocaine use changes the amount and activity of various proteins affecting brain function. view more (2008-05-28)
Mental and physical exercise delays dementia in fatal genetic disease
Scientists at Melbourne's Howard Florey Institute have discovered that mental and physical stimulation delays the onset of dementia in the fatal genetic disease, Huntington's disease. view more (2008-01-24)
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 times when we are better suited to multitask. view more (2008-09-03)
Carnegie Mellon study identifies where thoughts of familiar objects occur inside the human brain
A team of Carnegie Mellon University computer scientists and cognitive neuroscientists, combining methods of machine learning and brain imaging, have found a way to identify where people's thoughts and perceptions of familiar objects originate in the brain by identifying the patterns of brain activity associated with the objects. view more (2008-01-03)
First look: Princeton researchers peek into deepest recesses of human brain
A team of scientists from Princeton University has devised a new experimental technique that produces some of the best functional images ever taken of the human brainstem, the most primitive area of the brain. view more (2008-02-29)
Expectant brains help predict anxiety treatment success
A network of emotion-regulating brain regions implicated in the pathological worry that can grip patients with anxiety disorders may also be useful for predicting the benefits of treatment. view more (2009-01-05)
Brain's problem-solving function at work when we daydream
A new University of British Columbia study finds that our brains are much more active when we daydream than previously thought. view more (2009-05-12)
Researchers know what you were about to say; fMRI used to detect memory storage and retrieval
Using functional magnetic resonance imaging, or fMRI, researchers at the University of Pennsylvania and Princeton University have provided evidence that the act of recalling a memory is a bit like mental time travel. view more (2005-12-23)
Opiates and cannaboids: the fight against pain
Opiates and cannaboids, apart from being drugs, have curative properties. Thus, opiates (morphine, methadone, etc.) have been used for some time as a pain-reducer and many cannaboids have also analgesic properties. Regarding their curative aspects, it is very important to know the effects produced after a prolonged period of treatment. Carrying... view more... (2003-03-18)
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)
Autism problems explained in new research
New research from Melbourne's Howard Florey Institute helps to explain why children with autism spectrum disorders (autism) have problem-solving difficulties. view more (2005-10-25)
New non-invasive sensor can detect brainwaves remotely
Scientists have developed a remarkable sensor that can record brainwaves without the need for electrodes to be inserted into the brain or even for them to be placed on the scalp. Conventional electroencephalograms (EEGs) monitor electrical activity in the brain with electrodes placed either on the scalp (involving hair removal and skin abrasion)... view more... (2002-10-24)
Big picture of brain changes may be crucial to recovery from stroke injury
A study of patients who have difficulty paying attention to the left side of their environment has provided some of the first direct evidence that brain injury can cause detrimental functional changes in brain regions far from the site of the actual injury. view more (2005-10-18)
Scientists identify brain circuits used in sensation of touch
The ability to tactually recognize fine spatial details, such as the raised dots used in braille, is especially important to those who are blind. view more (2007-10-11)
Weizmann Institute scientists reveal how some aromas are bound up in our memories
From Proust's Madeleines to the overbearing food critic in the movie Ratatouille who's transported back to his childhood at the aroma of stew, artists have long been aware that some odors can spontaneously evoke strong memories. view more (2009-11-10)
How Rett Syndrome mutation targets the brain
Researchers have pinpointed why mutations that cause Rett Syndrome (RTT)-among the leading causes of mental retardation in females-specifically target the brain rather than other body tissues. view more (2006-10-19)
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...

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)
A mother's criticism causes distinctive neural activity among formerly depressed
Formerly depressed women show patterns of brain activity when they are criticized by their mothers that are distinctly different from the patterns shown by never depressed controls, according to a new study from Harvard University. view more (2009-04-01)
A new and safer technique in heart surgery
The new technique of SELECTIVE CEREBRAL PERFUSION has been successfully applied for the first time in the Basque Autonomous Community (B.A.C.). Surgeons keep a patient in a state of hibernation at 15 degrees centigrade, without brain activity and with heart circulation and respiratory activity at a standstill for one hour while an aorta implant is... view more...
