Study gives more proof that intelligence is largely inherited
They say a picture tells a thousand stories, but can it also tell how smart you are? Actually, say UCLA researchers, it can. view more (2009-03-18)
Master regulator found for regenerating nerve fibers in live animals
Researchers at Children's Hospital Boston report that an enzyme known as Mst3b, previously identified in their lab, is essential for regenerating damaged axons (nerve fibers) in a live animal model, in both the peripheral and central nervous systems. view more (2009-10-26)
Growth factor stimulates rapid extension of key motor neurons in brain
A growth factor known to be important for the survival of many types of cells stimulates rapid extension of corticospinal motor neurons - critical brain cells that connect the cerebral cortex with the spinal cord and that die in motor neuron diseases like amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease). view more (2006-11-06)
Neurons hard wired to tell left from right
It's well known that the left and right sides of the brain differ in many animal species and this is thought to influence cognitive performance and social behaviour. For instance, in humans, the left half of the brain is concerned with language processing whereas the right side is better at comprehending musical melody. view more (2008-03-31)
Engineers study brain folding in higher mammals
Engineers at Washington University in St. Louis are finding common ground between the shaping of the brain and the heart during embryonic development. view more (2007-10-02)
Nerves controlling muscles are best repaired with similar nerves
When repairing severed or damaged motor nerves with a donor nerve graft, surgeons have traditionally used a sensory nerve from another area of the patient's body. However, these patients often do not fully regain function in the injured area. view more (2007-05-14)
Brain memory area modifies its wiring diagram during the female cycle
Researchers at Northwestern University and Columbia University have found that "wiring" in female rat brain memory area expands and retracts in relation to the amount of estrogen present during the estrous/menstrual cycle. view more (2005-11-15)
Spinal cord bridge bypasses injury to restore mobility
The body's spinal cord is like a super highway of nerves. When an injury occurs, the body's policing defenses put up a roadblock in the form of a scar to prevent further injury, but it stops all neural traffic from moving forward. view more (2006-08-21)
Researchers Disprove 15-year-old Theory about the Nervous System
A delay in traffic may cause a headache, but a delay in the nervous system can cause much more. University of Missouri researchers have uncovered clues identifying which proteins are involved in the development of the nervous system and found that the proteins previously thought to play a significant role, in fact, do not. view more (2009-02-04)
Cell-surface sugar defects may trigger nerve damage in multiple sclerosis patients
Defects on cell-surface sugars may promote the short-term inflammation and long-term neurodegeneration that occurs in the central nervous system of multiple sclerosis patients, according to University of California, Irvine researchers. view more (2007-09-21)
Breakdown of Myelin Implicated in Alzheimer's, UCLA Research Shows
Wisdom comes with age (doesn't it?), but not without a process that takes place in the brain called myelination. Myelin is the fatty sheath that coats the axons of the nerves, allowing for efficient conduction of nerve impulses. view more (2007-05-14)
UCLA Research Implicates Myelin in Early Evolution of Huntington's Disease
Last month, Dr. George Bartzokis, director of the UCLA Memory Disorders and Alzheimer's Disease Clinic, suggested in the journal Alzheimer's & Dementia that the breakdown of a type of myelin that develops late in life promotes the buildup of toxic amyloid plaques long associated with Alzheimer's disease. view more (2007-06-12)
MIT identifies cells for spinal-cord repair
A researcher at MIT's Picower Institute for Learning and Memory has pinpointed stem cells within the spinal cord that, if persuaded to differentiate into more healing cells and fewer scarring cells following an injury, may lead to a new, non-surgical treatment for debilitating spinal-cord injuries. view more (2008-07-22)
Protein regulates movement of mitochondria in brain cells
Scientists have identified a protein in the brain that plays a key role in the function of mitochondria - the part of the cell that supplies energy, supports cellular activity, and potentially wards off threats from disease. view more (2009-06-15)
Mutation may cause inherited neuropathy
Mutations in a protein called dynein, required for the proper functioning of sensory nerve cells, can cause defects in mice that may provide crucial clues leading to better treatments for a human nerve disorder known as peripheral neuropathy, which affects about three percent of all those over age 60. view more (2007-12-26)
Mutant gene shatters nerves
If you bend a knee or an elbow, the nerves in your limbs stretch but do not break. A University of Utah study suggests why: A gene produces a springy protein that keeps nerve cells flexible. When the gene was disabled in tiny nematode worms, their nerve cells literally broke. view more (2007-01-30)
3 proteins may play important role in nerve-cell repair
Some mature brain cells can grow new extensions when the amount of three particular proteins on their surface increases, a new study shows. view more (2007-04-12)
Imaging study links key genetic risk for Alzheimer's disease to myelin breakdown
A new UCLA imaging study shows that age-related breakdown of myelin, the fatty insulation coating the brain's internal wiring, correlates strongly with the presence of a key genetic risk factor for Alzheimer disease. view more (2006-01-03)
New imaging technique could promote early detection of multiple sclerosis
Researchers from Purdue University have studied and recorded how myelin degrades real-time in live mice using a new imaging technique. Myelin is the fatty sheath coating the axons, or nerve cells, that insulate and aid in efficient nerve fiber conduction. In diseases such as multiple sclerosis, the myelin sheath has been found to degrade. view more (2007-06-28)
RNA-associated introns guide nerve-cell channel production
Researchers at the University of Pennsylvania School of Medicine have discovered that introns, or junk DNA to some, associated with RNA are an important molecular guide to making nerve-cell electrical channels. view more (2008-02-06)
