New findings on brain tumors called ependymomas

Brain tumors called ependymomas that occur in different parts of the central nervous system appear to arise from subpopulations of stem cells called radial glia cells (RGCs), according to investigators at St. Jude Children's Research Hospital. The discovery explains why some identical-looking ependymomas are actually distinctly different diseases, the researchers said.

Our own mind and body give us the foundation to understand what other people are doing, thinking, or feeling

Successful social communication is based, above all, on the ability to understand the actions of other people. But how can we imagine what other people are thinking, or what intentions they have? Psychologists and neuroscientists trace it back to a kind of simulation that goes on in our brain as soon as we observe a person acting.

Discovery has implications for research on restoring mobility to people who have lost motor functions due to spinal cord injury

Yale School of Medicine researchers report in Science this week genetic evidence for the hypothesis that myelination, or formation of a protective sheath around a nerve fiber, consolidates neural circuitry by suppressing plasticity in the mature brain.

Key neural system at risk from prenatal exposure to alcohol

In a study of adult monkeys who were exposed to moderate amounts of alcohol in utero, scientists have found that prenatal exposure to alcohol - even in small doses - has pronounced effects on the development and function later in life of the brain's dopamine system, a critical component of the central nervous system that regulates many regions of the brain.

SARS can infiltrate brain tissue

Severe acute respiratory syndrome (SARS), by its very name, indicates a disease of the respiratory tract. But SARS can also infiltrate brain tissue, causing significant central nervous system problems, according to an article in the Oct. 15 issue of Clinical Infectious Diseases, now available online.

Soldiers at risk for heat illnesses

A study reviewing 22 years of data on heat illness hospitalizations and deaths in the U.S. Army indicates soldiers remain at risk for exertional heat illness. While hospitalization rates for heat illnesses have declined over this period, cases of heat stroke have increased.

Single molecular anchor holds the key to treating many types of bacterial meningitis

By blocking the molecule's anchoring ability, researchers may be able to find a way to stave off the most common serious infection of the central nervous system and a major cause of childhood death and disability. The researchers' findings appear in the September 2005 issue of the Journal of Clinical Investigation.
