Without glial cells, animals lose their senses
Sensory neurons have always put on a good show. But now, it turns out, they'll be sharing the credit. In groundbreaking research to appear in the October 31 issue of Science, Rockefeller University scientists show that while neurons play the lead role in detecting sensory information, a second type of cell, the glial cell, pulls the strings behind... view more...

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, enabling them to respond appropriately. The... 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 issue of the journal Neuron. 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)
MIT neuroscientists find neural stopwatch in the brain
MIT researchers have identified populations of neurons that code time with extreme precision in the primate brain. These neurons are found in two interconnected brain regions, the prefrontal cortex and the striatum, both of which are known to play critical roles in learning, movement, and thought control. view more (2009-10-20)
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 suspect. 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)
New step in DNA damage response in neurons discovered
Researchers have identified a biochemical switch required for nerve cells to respond to DNA damage. view more (2009-01-20)
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)
Cocaine-induced synaptic plasticity linked to persistent addictive behaviors
The persistent nature of addiction is its most devastating feature. Understanding the mechanism underlying this phenomenon is the key for designing efficient therapy. Two separate studies published by Cell Press is the August 14 issue of the journal Neuron identify specific cocaine-induced changes in dopamine (DA) neurons that play a pivotal role... view more...

MIT: Stem-cell therapies for brain more complicated than thought
An MIT research team's latest finding suggests that stem cell therapies for the brain could be much more complicated than previously thought. view more (2007-11-28)
Therapeutic cloning treats Parkinson's disease in mice
Research led by investigators at Memorial Sloan-Kettering Cancer Center (MSKCC) has shown that therapeutic cloning, also known as somatic-cell nuclear transfer (SCNT), can be used to treat Parkinson's disease in mice. The study's results are published in the March 23 online edition of the journal Nature Medicine. view more (2008-03-24)
Mapping the neural landscape of hunger
The compelling urge to satisfy one's hunger enlists structures throughout the brain, as might be expected in a process so necessary for survival. view more (2006-08-17)
Study of the drug, Isradipine, to determine if it slows or prevents Parkinson's disease
Gloria E. Meredith, Ph.D., collaborated with D. James Surmeier, Ph.D. and other scientists at Northwestern University to study the drug, Isradipine, and its possible effects on Parkinson's disease. view more (2007-06-14)
Mechanism of nicotine's learning effects explored
While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory—a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder. view more (2007-04-05)
New research promising for improving brain cell survival after brain injury
Scientists at Melbourne's Howard Florey Institute have found a protein in the brain that can save neurons from dying after experiencing traumatic brain injury from incidents such as stroke, car accidents and falls. view more (2006-07-11)
