Bypassing stem cells, scientists make neurons directly from human skin
Aug 04, 2011
Researchers have come up with a recipe for making functional neurons directly from human skin cells, including those taken from patients with Alzheimer disease. The new method may offer a critical short cut for generating neurons for replacement therapies of the future, according to research published in the August 5th issue of the journal Cell.
Small hippocampus associated with depression in the elderly: risk factor or shrinkage?
Jul 19, 2011
A new study published in Biological Psychiatry suggests small hippocampal volume in depressed patients more likely an effect of depression rather than a cause.
Is meditation the push-up for the brain?
Jul 14, 2011
A new study suggests that people who meditate have stronger connections between brain regions and show less age-related brain atrophy. And significantly, these effects are evident throughout the entire brain, not just in specific areas.
Breathing restored after spinal cord injury in rodent model
Jul 13, 2011
Researchers at Case Western Reserve University School of Medicine bridged a spinal cord injury and biologically regenerated lost nerve connections to the diaphragm, restoring breathing in an adult rodent model of spinal cord injury. The work, which restored 80% to more than 100% of breathing function, will be published in the online issue of the journal Nature July 14.
Preventive use of one form of vitamin E may reduce stroke damage
Jul 07, 2011
Ten weeks of preventive supplementation with a natural form of vitamin E called tocotrienol in dogs that later had strokes reduced overall brain tissue damage, prevented loss of neural connections and helped sustain blood flow in the animals’ brains, a new study shows.
Overlooked peptide reveals clues to causes of Alzheimer disease
Jul 07, 2011
Researchers have shed light on the function of a little-studied amyloid peptide in promoting Alzheimer disease. Their surprising findings reveal that the peptide is more abundant, more neurotoxic, and exhibits a higher propensity to aggregate than amyloidogenic agents studied in earlier research, suggesting a potential role in new approaches for preventing Alzheimer disease-causing amyloidosis.
