Social interactions can alter gene expression in the brain, and vice versa
Our DNA determines a lot about who we are and how we play with others, but recent studies of social animals (birds and bees, among others) show that the interaction between genes and behavior is more of a two-way street than most of us realize.   view more (2008-11-07)

Nicotine rush hinges on sugar in neurons
When nicotine binds to a neuron, how does the cell know to send the signal that announces a smoker's high"   view more (2007-07-23)

UF experts: Decaffeinated coffee is not caffeine-free
Coffee addicts who switch to decaf for health reasons may not be as free from caffeine's clutches as they think. A new study by University of Florida researchers documents that almost all decaffeinated coffee contains some measure of caffeine.   view more (2006-10-11)

Study provides insight into how the brain loses plasticity of youth
A protein once thought to play a role only in the immune system could hold a clue to one of the great puzzles of neuroscience: how do the highly malleable and plastic brains of youth settle down into a relatively stable adult set of neuronal connections?   view more (2006-08-21)

Brain reacts to fairness as it does to money and chocolate
The human brain responds to being treated fairly the same way it responds to winning money and eating chocolate, UCLA scientists report. Being treated fairly turns on the brain's reward circuitry.   view more (2008-04-22)

Training and experience can affect brain organization, research shows
New research comparing music conductors and non-musicians shows that both the conductors and the non-musicians "tuned out" their visual sense while performing a difficult hearing task.   view more (2007-11-05)

New discoveries about neuron plasticity linked to learning and memory
Neurons experience large-scale changes across their dendrites during learning, say neuroscientists at The University of Texas at Austin in a new study that highlights the important role that these cell regions may play in the processes of learning and memory.   view more (2005-11-02)

Lipids play important role in nervous system development
Blocking a signaling lipid can keep nerves from developing the arm-like extensions they need to wire the body and may even cause neurons to die, researchers have found.   view more (2005-10-25)

Medical students respond positively to simulated patient experience
When a vomiting, simulated patient mannequin was rolled into the lecture hall last fall to teach large numbers of first- and second-year Wake Forest University School of Medicine students about the brain and nervous system, Michael T. Fitch, M.D., Ph.D., wasn't sure what to expect.   view more (2007-07-23)

Study breaks ground in revealing how neurons generate movement
When the eye tracks a bird's flight across the sky, the visual experience is normally smooth, without interruption. But underlying this behavior is a complex coordination of neurons that has remained mysterious to scientists.   view more (2008-04-25)

Research finds music training 'tunes' human auditory system
A newly published study by Northwestern University researchers suggests that Mom was right when she insisted that you continue music lessons — even after it was clear that a professional music career was not in your future.   view more (2007-03-13)

Study provides new insights into brain organisation
Scientists have provided new insights into how the brain is organised-knowledge which could eventually inform diagnosis of and treatments for conditions like Alzheimer's Disease and autism.   view more (2006-08-02)

Enzyme action creates protein linked to Alzheimer's disease
Researchers at UT Southwestern Medical Center have defined a key step in the production of beta-amyloid, a short protein that is thought to be responsible for the development of Alzheimer's disease.   view more (2005-08-15)

'Fetal' neurons play role in adult brain
Subplate neurons - once thought to die after directing the wiring of the cerebral cortex or gray matter- remain in the white matter of the adult brain in small numbers and maintain activity, communicating with other neurons in the brain said researchers from Baylor College of Medicine and the... view more (2007-09-12)

Nerve cells derived from stem cells and transplanted into mice may lead to improved brain treatments
Scientists at the Burnham Institute for Medical Research have, for the first time, genetically programmed embryonic stem (ES) cells to become nerve cells when transplanted into the brain, according to a study published today in The Journal of Neuroscience.   view more (2008-06-25)

Brain cell growth diminishes long before old age strikes, animal study shows
Even early in adulthood, aging begins to slow the mind's growth -- but it does not have to stop it altogether, suggests a Princeton University study on the brains of adult monkeys.   view more (2007-10-16)

Research suggests cause of neurodegeneration in Huntington's disease
The severe neurodegeneration associated with Huntington's disease may result from molecular mutations that block the transport of nutrients within cells.   view more (2006-05-31)

Brain networks change according to cognitive task
Using a newly released method to analyze functional magnetic resonance imaging (fMRI), Northwestern University researchers have demonstrated that the interconnections between different parts of the brain are dynamic and not static.   view more (2005-06-02)

New dyslexia theory blames 'noise'
The dyslexic brain struggles to read because even small distractions can throw it off, according to a new model of dyslexia emerging from a group of recent studies.   view more (2006-12-14)

Nanowire arrays can detect signals along individual neurons
Opening a whole new interface between nanotechnology and neuroscience, scientists at Harvard University have used slender silicon nanowires to detect, stimulate, and inhibit nerve signals along the axons and dendrites of live mammalian neurons.   view more (2006-08-25)

N.Y. Research Team Discovers How Antidepressants and Cocaine Interact with Brain Cell Targets
In a first, scientists from Weill Cornell Medical College and Columbia University Medical Center have described the specifics of how brain cells process antidepressant drugs, cocaine and amphetamines. These novel findings could prove useful in the development of more targeted medication therapies... view more (2008-07-30)

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)

Conflict of interest in psychopharmacology: can dr Jekyll still control Mr Hyde?
Giovanni A. Fava (Professor of Clinical Psychology at the University of Bologna) comments on several issues rising from the Nemeroff affair (the scandal following failure of disclose conflict of interest in an article that appeared in Nature Neuroscience). The main point is the fact that one... view more (2004-01-12)

The accumulation of sugar in neurons may explain the origin of several neurodegenerative diseases
A phenomenon considered healthy for cells, such as the accumulation of long chains of glucose (glycogen), which tissues store for energy purposes, is harmful for neurons.   view more (2007-10-22)

Pediatric Ritalin Use May Affect Developing Brain, New Study Suggests
Use of the attention deficit/hyperactivity disorder (ADHD) drug Ritalin by young children may cause long-term changes in the developing brain, suggests a new study of very young rats by a research team at Weill Cornell Medical College in New York City.   view more (2007-07-20)
