A resetting signal keeps circadian rhythm on track in Drosophila fruit flies
A Brandeis University study published this week in Nature shows for the first time that a molecular signal maintains coherence among brain clock cells that regulate daily activity of Drosophila melanogaster (fruit flies). view more (2005-11-10)
New research identifies gene important for nicotine's effects on the brain
New research identifies an important gene that influences several aspects of nicotine-induced behaviors in the brain. The study, funded by National Institutes of Drug Abuse, was presented today at the American College of Neuropsychopharmacology's Annual Meeting. view more (2006-12-06)
Young adults at future risk of Alzheimer's have different brain activity, says study
Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise. view more (2009-04-07)
Subordinate monkeys more likely to choose cocaine over food
Having a lower social standing increases the likelihood that a monkey faced with a stressful situation will choose cocaine over food, according to a study at Wake Forest University School of Medicine. More dominant monkeys undergoing the same stressful situation had fewer changes in brain activity in areas of the brain involved in stress and... view more... (2008-04-07)
Aging impairs the 'replay' of memories during sleep
Aging impairs the consolidation of memories during sleep, a process important in converting new memories into long-term ones. view more (2008-07-30)
Bioluminescence at the service of a novel cerebral imaging technique
CNRS scientists in collaboration have developed a new technique for the in vivo imaging of neuronal function using bioluminescence, based on a GFP-aequorin fusion protein. view more (2007-04-17)
During exercise, the human brain shifts into high gear on 'alternative energy'
Alternative energy is all the rage in major media headlines, but for the human brain, this is old news. According to a study by researchers from Denmark and The Netherlands published in the October 2008 print issue of The FASEB Journal, the brain, just like muscles, works harder during strenuous exercise and is fueled by lactate, rather than... view more...

Mathematical analysis techniques for the study of epilepsy
Dr. Elena Urrestarazu has employed a mathematical technique, known as Independent Components Analysis, in order to separate brain activities of different origins. In her PhD, defended at the Faculty of Medicine of the University of Navarre, Dr. Urrestarazu demonstrated that this technique could be applied brain registers in humans. view more (2004-11-12)
Brain waves show sound processing abnormalities in autistic children
Abnormalities in auditory and language processing may be evaluated in children with autism spectrum disorder by using magnetoencephalography (MEG), according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). view more (2008-12-01)
Millisecond brain signals predict response to fast-acting antidepressant
Images of the brain's fastest signals reveal an electromagnetic marker that predicts a patient's response to a fast-acting antidepressant, researchers have discovered. view more (2008-10-03)
Placebo study frames depression treatment puzzle
Treating major depression can be quite a puzzle, and a newly published UCLA study suggests medication is just one of many potential pieces. view more (2006-08-01)
Disease activity increases after MS patients stop drug
People with multiple sclerosis who stop taking the drug natalizumab may experience a rebound increase in disease activity. view more (2007-09-13)
Lighting up the human brain at night
Most people are aware that light affects human behaviour and can be used to treat disorders such as Seasonal Affective Disorder, but now researchers from the University of Surrey and the University of Liege have found new evidence that light administered during the night immediately reduces sleepiness and boosts human brain function. These... view more... (2004-10-25)
Measuring brain activity for emotional markers that may indicate risk for developing alcoholism
Although prior research has looked at brain activity and alcoholism, much of it has focused on cortical activity as a marker for impulsivity among alcoholics. A new study examines measures of brain activity in the frontal regions of the brain, thought to reflect individual differences in emotionality, an important aspect of personality. view more (2006-11-27)
Hypnosis study reveals brain's 'amnesia centers'
Brain scans of hypnotized people that are taken as they forget and are triggered to remember have revealed neural circuitry that is key to the memory suppression and recall process. view more (2008-01-10)
Deep brain mapping to isolate evidence of Gulf War syndrome
Researchers at Southern Methodist University in Dallas are pioneering the use of spatial statistical modeling to analyze brain scan data from Persian Gulf War veterans, aiming to pinpoint specific areas of the their brains affected by Gulf War Syndrome. view more (2008-11-20)
New Brain Test to Monitor Alzheimer's Disease
A new test that taps brain records so accurately it caught out a serial killer, could soon be used by pharmaceutical companies to speed up approval of drugs for Alzheimer's and other brain diseases, reports Marina Murphy in Chemistry & Industry Magazine. 'Brain Fingerprinting' is the patented technology that can measure objectively, for the... view more... (2004-03-15)
Hand-to-ear link in brain established after minutes of piano learning
Contrary to what your music teacher told you, it does not take decades of piano practice to learn to play phrases on the piano without looking at your fingers. A brain map linking finger movements with particular notes begins to form within minutes of starting training, according to research published this week in BMC Neuroscience. Recent brain... view more... (2003-10-09)
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)
MPI researchers have for the first been able to map the activity of the brain by means of electrical microstimulation
The combination of electrical microstimulation and FMRT promises substantially more precise insights into the functional organisation or the brain and its circuitry. view more (2005-12-23)
