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)
A new analysis suggests that schizophrenia may be caused by an interaction of genes and viruses in glia cells
A report in the open access journal BMC Psychiatry presents a new hypothesis that may explain the causes of the psychiatric disease, schizophrenia. The hypothesis hinges on glia, a special type of cell, which is important for the maintenance of the connections between brain cells. By re-examining previously published research the authors suggest... view more... (2002-07-25)
Breakdown of myelin insulation in brain's wiring implicated in childhood developmental disorders
New evidence points to production of myelin, a fatty insulation coating the brain's internal wiring, as a neural Achilles' heel early in life. view more (2005-11-15)
Bigger brain size matters for intellectual ability
Brain size matters for intellectual ability and bigger is better, McMaster University researchers have found. view more (2005-12-23)
'Gateway' gene discovered for brain cancer
Researchers have discovered that the same genetic regulator that triggers growth of stem cells during brain development also plays a central role in the development of the lethal brain cancer malignant glioma. view more (2007-02-15)
Rutgers Scientists Discover Brain Cell Development Process Implicated in Mental Retardation, Finding May Lead to New Drug Therapies
Scientists at Rutgers, The State University of New Jersey, have discovered a biological process in brain cell development that may help explain some causes of mental retardation. This understanding may one day help other researchers develop therapies that can reduce specific forms of retardation. view more (2007-08-01)
Newly-identified exercise gene could help with depression
Boosting an exercise-related gene in the brain works as a powerful anti-depressant in mice-a finding that could lead to a new anti-depressant drug target, according to a Yale School of Medicine report in Nature Medicine. view more (2007-12-03)
Gene therapy inhibits epilepsy in animals
For the first time, researchers have inhibited the development of epilepsy after a brain insult in animals. By using gene therapy to modify signaling pathways in the brain, neurology researchers found that they could significantly reduce the development of epileptic seizures in rats. view more (2006-11-09)
Important New Research Identifies How Brain Cells Die During A Stroke
Medical Research Council (MRC) scientists, in collaboration with colleagues from British and Italian universities, have unveiled a mechanism that causes the death of brain cells (neurons) in stroke. The discovery may help explain why some therapy approaches for stroke have been unsuccessful and identifies potential research avenues for the... view more... (2005-01-25)
Epsilon4 allele carriers show altered brain activity before onset of Alzheimer's symptoms
Healthy individuals who are at risk of Alzheimer's disease show reduced activity in the hippocampal region of the brain when performing tasks related to forming new memories. view more (2006-01-13)
Mechanism in cells that generate malignant brain tumors may offer target for gene therapy
Researchers at Cedars-Sinai Medical Center's Maxine Dunitz Neurosurgical Institute who first isolated cancer stem cells in adult brain tumors in 2004 have now identified a molecular mechanism that is involved in the development of these cells from which malignant brain tumors may originate. view more (2008-10-27)
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 neurodegeneration, Yale School of Medicine... view more...

Research links 'ecstasy' to survival of key movement-related cells in brain
New research from the University of Cincinnati (UC) suggests that the widely abused club drug "ecstasy," or MDMA, can increase the survival of dopamine cells in the brain during fetal development. view more (2006-10-19)
Is brain size linked to two common gene variants?
Human brain size is hereditary, but the genes that influence brain size in healthy people are unknown. view more (2006-05-17)
Ultrasound affects embryonic mouse brain development
The prolonged and frequent use of ultrasound on pregnant mice causes brain abnormalities in the developing mouse fetus. view more (2006-08-08)
Effects of preterm birth and early environmental risks continue into adolescence
In one of the first studies to use brain imaging with adolescents born prematurely, New Jersey researchers report that the effects of premature birth and environmental risks on the brain during the first three years of childhood continue through adolescence. view more (2006-03-22)
Cellular cues identified for stroke recovery
When a stroke strikes, the supply of blood to the part of the brain affected is interrupted, starving it of oxygen. Brain cells can be seriously damaged or die, impairing local brain function. view more (2006-12-26)
PET scans may help assess presence of brain plaques related to Alzheimer's disease
A type of positron emission tomography (PET) scanning may be useful in a non-invasive assessment of the formation of Alzheimer's disease-related plaques in the brain, according to small study posted online today that will appear in the October 2008 print issue of Archives of Neurology, one of the JAMA/Archives journals. view more (2008-08-12)
Family history of brain tumors linked to increased risk of brain cancer
People with a family history of cancerous brain tumors appear to be at higher risk of developing the same kind of tumors compared to people with no such family history. view more (2008-09-22)
Hard-wiring the fruit fly's visual system
Both vertebrate and fruit fly have so-called visual maps in the brain that represent the world they see. view more (2006-09-21)
