Sleep chemical central to effectiveness of deep brain stimulation
A brain chemical that makes us sleepy also appears to play a central role in the success of deep brain stimulation to ease symptoms in patients with Parkinson's disease and other brain disorders. The surprising finding is outlined in a paper published online Dec. 23 in Nature Medicine. view more (2007-12-26)
Chemotherapy can be more toxic to brain cells than to cancer cells and may cause brain damage
Drugs used to treat cancer may damage normal, healthy brain cells more than the cancer cells they are meant to target. view more (2006-11-30)
Blood flow in brain takes a twist, affecting views of Alzheimer's
New findings that long-overlooked brain cells play an important role in regulating blood flow in the brain call into question one of the basic assumptions underlying today's most sophisticated brain imaging techniques and could open a new frontier when it comes to understanding Alzheimer's disease. view more (2006-01-06)
Novel stem cell technology leads to better spinal cord repair
Researchers believe they have identified a new way, using an advance in stem-cell technology, to promote recovery after spinal cord injury of rats, according to a study published in today's Journal of Biology. view more (2006-04-28)
Johns Hopkins scientists map brain area that may aid hunt for human brain stem cells
A study led by a Johns Hopkins neurosurgeon has provided the first comprehensive map of a part of the adult human brain containing astrocytes, cells known to produce growth factors critical to the regeneration of damaged neural tissue and that potentially serve as brain stem cells. view more (2006-02-17)
New study proves that pain is not a symptom of arthritis, pain causes arthritis
Pain is more than a symptom of osteoarthritis, it is an inherent and damaging part of the disease itself, according to a study published today in journal Arthritis and Rheumatism. view more (2008-09-30)
Roots of epilepsy may lie in oft-ignored brain cells
Star-shaped brain cells that are often overlooked by doctors and scientists as mere support cells appear to play a key role in the development of epilepsy. view more (2005-08-15)
Naturally occurring enzyme can break down key part of Alzheimer's plaques
Scientists have identified a naturally occurring enzyme that can break down a key component of the brain plaques characteristic of Alzheimer's disease. view more (2006-10-25)
Epilepsy and brain pathology linked together by the protein ADK
The brain of individuals who suffer from epilepsy is characterized by astrogliosis, a brain pathology evidenced by a complex series of changes in the morphology and function of brain cells known as astrocytes. view more (2008-01-03)
New therapeutic target identified in inherited brain tumor disorder
Researchers studying a mouse model of neurofibromatosis 1 (NF1), a genetic condition that causes childhood brain tumors, have found their second new drug target in a year, a protein called methionine aminopeptidase-2 (MetAP2). view more (2005-11-02)
How genetic malfunction causes a form of retardation
Researchers have discovered that the genetic malfunction that causes a form of mental retardation called Noonan Syndrome (NS) produces an imbalance in the genesis of two types of cells in the developing embryonic brain. view more (2007-04-19)
Uric acid and spinal cord injury treatment
Uric acid is commonly associated with the excruciatingly painful joint disease known as gout, but it can also play a crucial role in the treatment of spinal cord injury and other central nervous system disorders, such as stroke, multiple sclerosis and Parkinson's disease, according to Rutgers' Bonnie Firestein. view more (2007-01-04)
Cancer immunoresistance linked to loss of tumor suppressor gene
Cancer immunoresistance may be partially due to loss of a well-known tumor suppressor gene, according to new research led by Andrew T. Parsa, MD, PhD, assistant professor of neurological surgery at the University of California, San Francisco. view more (2006-12-11)
Scientists Uncover Potential Key to Brain Blood-Flow Disorders
Scientists at the University of Vermont have clarified the cellular process responsible for signaling regional blood flow changes in the brain, thereby uncovering possible causes for such disorders as stroke, migraine, and Alzheimer's disease. view more (2007-01-04)
Water channel protein implicated in relative of multiple sclerosis
Researchers have identified a molecular suspect in a disorder similar to multiple sclerosis (MS) that attacks the optic nerve and spinal cord, according to a report presented at the 130th annual meeting of the American Neurological Association in San Diego. view more (2005-09-22)
The immune system and Alzheimer's disease
Utrecht researchers, funded by NWO, have determined the role played by brain cells from the immune system that are located close to dying memory cells. The research will help determine the causes of Alzheimer's disease. In patients with Alzheimer's disease, the brain cells die off. The death of these neurones takes place primarily in the vicinity... view more... (2001-11-27)
Stem cell research produces a key discovery for Fragile X Syndrome
An important finding has been made by McMaster researchers about Fragile X Syndrome (FXS), a sex-linked genetic disorder that affects approximately one in 4,000 males and one in 6,000 females. view more (2007-09-11)
Cancer gene drives pivotal decision in early brain development
A gene linked to pediatric brain tumors is an essential driver of early brain development, researchers at Washington University School of Medicine in St. Louis have found. view more (2007-11-14)
Insight into neural stem cells has implications for designing therapies
Scientists have discovered that adult neural stem cells, which exist in the brain throughout life, are not a single, homogeneous group. view more (2007-07-09)
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)
