Neural signal that helps wire up brain's movement circuit identified
Scientists from Imperial College London and King`s College London have identified a molecule that helps to wire up the neural circuitry responsible for controlling the movement of muscle. Writing today in the journal Neuron, the researchers describe how the signalling protein named WNT-3 directs... view more (2002-09-10)

New brain cells listen before they talk
Newly created neurons in adults rely on signals from distant brain regions to regulate their maturation and survival before they can communicate with existing neighboring cells-a finding that has important implications for the use of adult neural stem cells to replace brain cells lost by trauma or... view more (2007-10-31)

Scientists produce neurons from human skin
Scientists from Université Laval's Faculty of Medicine have succeeded in producing neurons in vitro using stem cells extracted from adult human skin.   view more (2007-02-23)

Researchers pinpoint molecular basis for phantom pain
Yale researchers report the first evidence that phantom pain following spinal cord injury is the result of hypersensitive neurons in the thalamic region of the brain that can be suppressed with specially designed molecular agents.   view more (2005-09-21)

Neurons for numerosity: Parietal neurons 'sum up' individual items in a group
As any child knows, to answer the question "how many," one must start by adding up individual objects in a group.   view more (2007-07-24)

A balanced memory network
Ever wonder how much information we put in our heads" The answer: a lot. For starters, a typical vocabulary is 50,000-250,000 words.   view more (2007-09-07)

Experience affects new neuron survival in adult brain; study sheds light on learning, memory
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults.   view more (2007-03-23)

Marine snail's neural network sheds light on the basis for flexible behavior
By studying how a relatively simple motor network of the marine snail Aplysia produces variants of a particular feeding behavior, researchers have found that the ability to generate a large number of behavioral variants stems from the elegant hierarchical architecture of the brain's motor network.   view more (2005-10-11)

How taste response is hard-wired into the brain
Instantly reacting to the sweet lure of chocolate or the bitter taste of strychnine would seem to demand that such behavioral responses be so innate as to be hard-wired into the brain.   view more (2006-01-19)

Adult neurogenesis newly adult-born neurons are functionally similar to mature neurons
In mammals, the production of new brain cells occurs primarily at the time the nervous system is developing, although certain brain areas generate neurons throughout adulthood. One such area is the hippocampus, a part of the brain involved in the critical function of memory and spatial perception.   view more (2006-11-21)

Identification of dopamine 'mother cells' could lead to future Parkinson's treatments
'Mother cells' which produce the neurons affected by Parkinson's disease have been identified by scientists, according to new research published in the journal Glia.   view more (2008-04-08)

A glimmer of hope in the struggle against neurodegenerative diseases: the virtues of proteins that can save dying neurons
Diseases characterized by neurodegeneration affect individuals over 50 years of age and they attack one particular class of neurons in the brain or spinal cord. The research interest of Professor Ann Kato and her team is principally focalized on ALS in which there is a progressive paralysis caused... view more (2002-01-25)

Striking the right balance between excitation and inhibition
Neurons in the brain and spinal cord come in two flavors, excitatory neurons that transmit and amplify signals, and inhibitory neurons that inhibit and refine those signals.   view more (2006-05-31)

Rewiring the mammalian brain - neurons make fickle friends
A new discovery from the Brain Mind Institute of the EPFL (Ecole Polytechnique Fédérale de Lausanne) shows that the brain rewires itself following an experience.   view more (2006-08-08)

Women At Greater Risk Of Brain-Cell Damage From Long-Term Ecstasy Use
Authors of a Dutch study in this week's issue of THE LANCET conclude that long-term ecstasy use-especially among women-could have serious negative effects on specific cells in the brain. The study also suggests that the adverse effects of ecstasy use can sometimes be reversed among people who stop... view more (2001-11-28)

New brain cells implicated in machinery of cannabinoid signaling
The brain cells called astrocytes, and not just neurons, are sensitive to the substances called cannabinoids-the active chemicals in marijuana.   view more (2008-03-27)

Research Explains How Lead Exposure Produces Learning Deficits
A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits.   view more (2007-04-04)

Pathways of emotion - from cortex to peripheral organs
Walking down a dark alley late at night is enough to give anyone the heebie-jeebies. Your heart starts racing, your palms get clammy and you get ready to run. Now researchers from Boston University have unravelled the neural pathways that transmit information about your surroundings to your organs,... view more (2003-10-07)

Tracing the formation of long-term memory
The formation of long-term memory in fruit flies can be demonstrated by the influx of calcium into cells called mushroom body neurons that occurs after special training that includes periods of rest, said researchers from Baylor College of Medicine (BCM) in a report that appears in the current... view more (2006-12-07)

Prefrontal cortex loses neurons during adolescence, researchers find
Researchers at the University of Illinois have found that adolescence is a time of remodeling in the prefrontal cortex, a brain structure dedicated to higher functions such as planning and social behaviors.   view more (2007-03-14)

Study suggests loss of 2 types of neurons -- not just 1 -- triggers Parkinson's symptoms
New evidence indicates that the loss of two types of brain cells--not just one as previously thought--may trigger the onset of symptoms associated with Parkinson's disease.   view more (2007-08-14)

New methods identify and manipulate 'newborn' cells in animal model of Parkinson's disease
When cells in the brain are lost through disease or injury, neighboring cells begin to divide and multiply, but only a few areas in the brain are able to produce new neurons.   view more (2008-09-04)

Adult brain cells are movers and shakers
It's a general belief that the circuitry of young brains has robust flexibility but eventually gets "hard-wired" in adulthood. As Johns Hopkins researchers and their colleagues report in the Nov. 8 issue of Neuron, however, adult neurons aren't quite as rigidly glued in place as we... view more (2007-11-09)

Obesity research boosted by watching hunger in the brain
Scientists can now measure how full or hungry a mouse feels, thanks to a new technique which uses imaging to reveal how neurons behave in the part of the brain which regulates appetite.   view more (2007-11-08)

Parkinson's mutation stunts neurons
Mutations in a key brain protein known to underlie a form of Parkinson's disease (PD) wreaks its damage by stunting the normal growth and branching of neurons, researchers have found.   view more (2006-11-27)
