Nerve-insulating substance called myelin can lead to functional improvements in animals with spinal cord injury

Combining partially differentiated stem cells with gene therapy can promote the growth of new "insulation" around nerve fibers in the damaged spinal cords of rats, a new study shows.

New insights into brain cell metabolism from PET and MRI scans

By discovering a crucial piece of submicroscopic information about how the brain converts fuel into energy for neurons, Cornell University biophysicists have gleaned new insights into brain cell metabolism that will allow neurologists to better interpret data from such diagnostic tests as positron emission tomography (PET) scans and a specialized magnetic resonance imaging (MRI) test.

Researchers successfully treat laboratory model of a lysosomal storage disease called GM1

Physicians might one day be able to treat a disease that destroys brain cells in children using genetically modified cells to transport a "drug" to the site of the dying neural cells (cells that transmit impulses).

Jumping genes help detemine uniqueness of individual brains

Scientists at the Salk Institute for Biological Studies may have found one explanation for the puzzling variety in brain organization and function: mobile elements, pieces of DNA that can jump from one place in the genome to another, randomly changing the genetic information in single brain cells.

Important new finding about the brain and its stem cells

A family's bravery and generosity in the face of their son's death three years ago has enabled researchers to make an important new finding about the brain and its stem cells.

Researchers insert engineered human stem cells into the spinal cords of ALS-afflicted rats

Unveiling a delivery method that may one day help surgeons treat the deadly neurodegenerative disease amyotrophic lateral sclerosis (ALS), researchers at the University of Wisconsin-Madison have inserted engineered human stem cells into the spinal cords of ALS-afflicted rats.

Research confirms how early-life events shape later physiology

Underscoring the value of good prenatal care, new research suggests that early infection may create a cognitive vulnerability that appears later during stress on the immune system.

Cells from skeletal muscle could be an important source of stem cells for repairing damaged muscle or nerve tissue

A group of cells called skeletal-muscle satellite cells are able to regenerate muscle fibres. Giulio Alessandri (Carlo Besta Neurological Institute, Milan, Italy) and colleagues investigated whether these cells can differentiate into different types of mesenchymal cell (the types of cell that eventually form connective tissue, bone, cartilage, and the circulatory and lymphatic systems).

In a world first, Australian researchers re-grow cut spinal cord

In a world first, Australian researchers have discovered a mechanism for greatly enhancing regrowth of spinal cord nerves after they are damaged, restoring the ability to walk in mice within weeks of a spinal cord injury.

Potential stem cells treatment for retinitis pigmentosa and other retinal degenerations

A team of researchers from The Scripps Research Institute was able to preserve visual function in mice that were genetically predisposed to developing a profound degenerative disease that destroys their retinas.

Discovery of way to regulate brain blood could lead to new treatments for stroke, migraine, Alzheimer’s

There may be new treatments for stroke, migraine, Alzheimer’s and other brain disorders, thanks to the discovery of a mechanism for regulating brain blood flow made by researchers at the University of British Columbia.

New treatment strategy for brain cancer

Virginia Commonwealth University Massey Cancer Center researchers have found that combining ionizing radiation with a secreted protein that selectively inhibits tumor cell growth and survival can target cancer cells and leave healthy cells alone, perhaps presenting a new approach for treating the deadliest type of brain tumor.

Adenosine triphosphate is a culprit in causing the devastating damage of spinal cord injury

ATP - adenosine triphosphate, the vital energy source that keeps our body’s cells alive, runs amok at the site of a spinal cord injury, pouring into the area around the wound and killing the cells that normally allow us to move, scientists report in the cover story of the August issue of Nature Medicine.

Positron emission tomography offers a better way to observe the damage that strokes and neurodegenerative diseases wreak on brain cells

A laser-based microscopy technique may have settled a long-standing debate among neuroscientists about how brain cells process energy

Significant vaccine advance for Parkinson’s disease therapy

Scientists at the University of Nebraska Medical Center in Omaha and Columbia University Medical Center in New York have discovered a new vaccine approach that successfully prevents the death of brain cells in a mouse model of Parkinson’s disease.

Curry offers possible protection against Alzheimer’s disease

A new study has found that curry, a common and popular cooking additive, could be an effective enhancer of an enzyme that protects the brain against oxidative conditions.
