Study implicates potassium channel mutations in neurodegeneration and mental retardation
For the first time, researchers have linked mutations in a gene that regulates how potassium enters cells to a neurodegenerative disease and to another disorder that causes mental retardation and coordination problems. view more (2006-02-27)
PneuStep — MRI-safe motor makes robotic biopsies possible
Engineers at the Johns Hopkins Urology Robotics Lab report the invention of a motor without metal or electricity that can safely power remote-controlled robotic medical devices used for cancer biopsies and therapies guided by magnetic resonance imaging. view more (2007-04-09)
New Target Found to Fight, Treat Parkinson's
Neuroscientists from the University at Buffalo have described for the first time how rotenone, an environmental toxin linked specifically to Parkinson's disease, selectively destroys the neurons that produce dopamine, the neurotransmitter critical to body movement and muscle control. view more (2005-08-25)
The people's robot
Industrial robot components are costly. For researchers or teachers, this means reaching deep into thin wallets. VolksBot, an affordable off-the-shelf solution, saves precious development time and brings robotics to the consumer market. It will be shown at CeBIT trade fair. When Commodore launched the first home computer on the German market - the... view more... (2004-02-26)
Prozac's target revealed
Researchers at Cold Spring Harbor Laboratory on Long Island have identified which among several different kinds of cells in the brain is the chief target of the widely prescribed antidepressant Prozac. view more (2006-05-16)
Slow brain waves play key role in coordinating complex activity
While it is widely accepted that the output of nerve cells carries information between regions of the brain, it's a big mystery how widely separated regions of the cortex involving billions of cells are linked together to coordinate complex activity. view more (2006-09-15)
A new mouse model provides insight into genetic neurological disorders
Neurosensory diseases are difficult to model in mice because their symptoms are complex and diverse. The genetic causes identified are often lethal when transferred to a mouse. view more (2009-05-26)
Scientists show how a neuron gets its shape
Ask a simple question, get a simple answer: When Abraham Lincoln was asked how long a man's legs should be, he absurdly replied, "Long enough to reach the ground." Now, by using a new microscopy technique to watch the growth of individual neurons in the microscopic roundworm Caenorhabditis elegans, Rockefeller University researchers are... view more...

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)
Newborn neurons like to hang with the 'in' crowd
Like any new kid on the block that tries to fit in, newborn brain cells need to find their place within the existing network of neurons. view more (2007-05-08)
Fruit flies' response to wind offers new window to neural circuits
Try this at home: If fruit flies are buzzing around your kitchen, switch on your hairdryer and aim it at the flies. A gentle stream of air will stop them in their tracks, putting them in prime position for swatting. view more (2009-03-18)
When neurons fire up: Study sheds light on rhythms of the brain
In our brains, groups of neurons fire up simultaneously for just milliseconds at a time, in random rhythms, similar to twinkling lightning bugs in our backyards. New research from neuroscientists at Indiana University and the University of Montreal provides a model -- a rhyme and reason -- for this random synchronization. view more (2008-08-06)
Neural stem cell differentiation factor discovered
Neural stem cells represent the cellular backup of our brain. These cells are capable of self-renewal to form new stem cells or differentiate into neurons, astrocytes or oligodendrocytes. view more (2009-06-30)
Defective movement of cell's power plants implicated in commom inherited neurological disorder
Contrary to previous thinking, the inefficient movement of cell's "power plants" -- the mitochondria -- within a cell, rather than their low energy production, may be a contributing factor in the development of Charcot-Marie-Tooth disease (CMT), new research shows. view more (2007-01-17)
The development of stem cells -- not only which and where but also WHEN
Yet another stride has been taken on the road to knowledge about the development of the nervous system. For the first time factors have been uncovered that decide when a cell is to develop into another cell. During the last ten years much progress has been made in finding out what determines how various types of nerve cells develop from a stem... view more... (2003-03-20)
First Neuroimaging Study Examining Motor Execution in Children With Autism Reveals Brain Activation Differences, Decreased Connectivity Between Brain Regions
In the first neuroimaging study to examine motor execution in children with autism, researchers at the Kennedy Krieger Institute have uncovered important new insight into the neurological basis of autism. view more (2009-04-30)
Prions link cholesterol to neurodegeneration
Prion infection of neurons increases the free cholesterol content in cell membranes. A new study published in the online open access journal BMC Biology suggests that disturbances in membrane cholesterol may be the mechanism by which prions cause neurodegeneration and could point to a role for cholesterol in other neurodegenerative diseases. view more (2008-02-12)
Turn-ons and turn-offs for neurons
Our brain consists of billions of nerve cells enabling to learn, remember and reason. Every time we think and experience, touch, smell or fear, millions of neurons in our brain becomes active. view more (2007-06-20)
Transcutaneous cervical esophageal ultrasound can not substitute for 24-h pH monitoring or manometry
24-h pH monitoring and esophageal manometry are the gold standards of methods used for diagnosing GER and esophageal motor disorders, respectively view more (2007-10-10)
Keeping herpes infection in check: Pitt researchers describe immune system strategies
Herpes simplex virus type I can cause bouts of cold sores, blindness and potentially lethal encephalitis when it reawakens from a quiescent state in the nerve cells it infects. view more (2008-10-10)
