Stroke Damage Is Less in Rats Given Opioids
Drugs induce a state of hibernation that improves recovery, study shows WEDNESDAY, June 17 (HealthDay News) -- Hibernation induced by opioid drugs reduced brain damage and behavioral dysfunction in a study of rats that experienced an experimental stroke, researchers report. "Studies...Scientists find city rats are loyal to their 'hoods
In the rat race of life, one thing is certain: there's no place like home. Now, a study just released in Molecular Ecology finds the same is true for rats. Although inner city rodents appear to roam freely, most form distinct neighborhoods where they spend the majority of their lives. Like an...Team Regrows Neurons Controlling Movement in Rats
Goal is to one day develop a therapy to help with spinal cord injuries MONDAY, April 6 (HealthDay News) -- Using genetically engineered cells and a virus as a delivery method, researchers were able to regenerate a type of nerve fiber in rat brains that controls movement. This isn't ...Mutant rats offer clues to medical mystery
HOUSTON (Feb. 17, 2009) A research project at Rice University has brought scientists to the brink of comprehending a long-standing medical mystery that may link cardiovascular disease, osteoporosis and perhaps even Alzheimer's disease. And for that, we can thank the rat. The recent paper i...Bound by attention: Bringing rats and humans together
When picking through a basket of fruit, it doesn't seem very difficult to recognize a green pear from a green apple. This is easy, thanks to "feature binding" a process by which our brain combines all of the specific features of an object and gives us a complete and unified picture of it. For exam...A good ear: Rats identify specific sounds in noisy environments
A study conducted on hundreds of rats could help us understand how the brain identifies specific sounds in a noisy environment. The investigation, soon to be published in the journal Brain, was conducted by Alex Martin of the Universit de Montral Department of Psychology. "Our ears have thousan...Researchers Create First Targeted Knockout Rats Using Zinc Finger Nuclease Technology

In the rat race of life, one thing is certain: there's no place like home. Now, a study published this week in the journal Molecular Ecology finds the same is as true for rats as for humans. Although inner city rodents appear to roam freely, most form distinct neighborhoods where they spe...Stem cells replace stroke-damaged tissue in rats
Effective stem cell treatment for strokes has taken a significant step forward today (09 March) as scientists reveal how they have replaced stroke-damaged brain tissue in rats. The team of scientists is funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and led by Dr M...4 days of REM sleep deprivation contributes to a reduction of cell proliferation in rats
WESTCHESTER, Ill. Four days exposure to a REM sleep deprivation procedure reduces cell proliferation in the part of the forebrain that contributes to long-term memory of rats, according to a study published in the February 1 issue of the journal SLEEP. The study, authored by Dennis McGinty, Ph...Glucose triggers brain cell death in rats after hypoglycemic coma
Brain damage that was thought to be caused by hypoglycemic coma actually occurs when glucose is administered to treat the coma, according to a study in rodents led by researchers at the San Francisco VA Medical Center. The results are surprising, say the authors, and may be of clinical significa...Metacognition: Faced with a test, rats can check their knowledge first
Researchers have found evidence that rats are capable of metacognition—that is, they can possess knowledge of their own cognitive states. This ability, which can also be thought of as the capacity to assess or reflect on one's own mental processes, was previously only recognized in humans and other...Human stem cell treatment restores motor function in paralyzed rats
Rats paralyzed due to loss of blood flow to the spine returned to near normal ambulatory function six weeks after receiving grafts of human spinal stem cells (hSSCs), researchers from the University of California, San Diego (UCSD) School of Medicine report. The study, led by Martin Marsala, M.D., ...USC researchers derive first embryonic stem cells from rats
Researchers at the University of Southern California (USC) have, for the first time in history, derived authentic embryonic stem (ES) cells from rats. This breakthrough finding will enable scientists to create far more effective animal models for the study of a range of human diseases.
