RESEARCH NEWS 1998-10-14 Research News A study published in last month's Neurology reports that professional soccer players are at significantly higher risk for long-term brain injuries that affect their mental function. These brain injuries result from either heading the ba
RESEARCH NEWS 1998-10-14 Research News A diet rich in certain fruits and vegetables is known to protect against cancer and heart disease, and now a new animal study in the October Journal of Neuroscience suggests nutrition can also stall the decline of brain function that comes w
RESEARCH NEWS 1998-10-13 Research News Estrogen has been shown in recent years to be a possible protective factor in Alzheimer disease, and now new studies suggest it may also protect against the risk of Parkinson's disease. Preliminary data from four studies were presented
RESEARCH NEWS 1998-10-13 Research News Secreted forms of amyloid precursor protein (APP) may play an important role in the formation and consolidation of memory, according to a study published in today's proceedings of the National Academy of Science. Researchers from the Un
RESEARCH NEWS 1998-09-17 Research News Mutations in the enzyme for superoxide dismutase (SOD1) have been linked to 15 to 20 percent of cases of amyotrophic lateral sclerosis (ALS), leading to a theory that the disease results when the defective enzyme allows super oxide radicals
RESEARCH NEWS 1998-09-12 Research News A mutation in the gene for PAK-3, a molecule that is thought to play a variety of roles in the nervous system, has been implicated in a form of X-chromosome-linked mental retardation affecting one in 100 males. People who have the mutation h
RESEARCH NEWS 1998-09-11 Research News Neuronal growth and synapse formation is regulated by a combination of activity-independent and activity-dependent mechanisms. In today's Science, E. Nedivi et al. describe CPG15, a molecule that enhances dendritic arbor growth in proje
RESEARCH NEWS 1998-09-10 Research News Glutamate is a neurotransmitter that is toxic when too much of it is released by excessive neuronal activity or by brain injury. Some researchers have also proposed that glutamate toxicity drives the neurodegeneration seen in Alzheimer'
RESEARCH NEWS 1998-09-10 Research News A study published in tomorrow's Science provides new details of how the transcription factor NF-κB protects cells from apoptosis. C.-Y. Wang and colleagues report they have identified four genes that are targets of NF-κB activity. The g
RESEARCH NEWS 1998-09-06 Research News A novel brain-imaging agent that binds selectively to dopamine transporter molecules promises to open up a window on the functioning of the brain's dopamine system. Dopamine is one of the brain's major neurotransmitters, and is imp
RESEARCH NEWS 1998-09-05 Research News Puny polymer pellets show promise as a vehicle for delivering nerve-growth factor (NGF) to the basal forebrain, where the substance could rescue or even regenerate neurons damaged by Alzheimer's disease. For some years, the idea of intr
RESEARCH NEWS 1998-09-03 Research News A 15-year study involving more than 100 families and 1,000 individuals has provided the first strong evidence of genetic susceptiblity to schizophrenia, within a stretch of chormosome 13. According to the international team, led by Ann Pulve
RESEARCH NEWS 1998-09-03 Research News The growing tips, or growth cones, of neurons are confronted with a chemical cacophany of growth-guiding cues. How do they know which ones to heed? In an article appearing in Science (4 September issue), H.-J. Song and colleagues report that
