Protecting brains of premature infants - new approach needed

A study of how the brain of a premature infant responds to injury has found vulnerabilities similar to those in the mature brain but also identified at least one significant difference, according to neuroscientists and neonatologists at Washington University School of Medicine in St. Louis.

Cell structures exhibit novel behaviors, mimic red blood cells and liquid crystals

Researchers at the University of Pennsylvania and Yale University have manipulated the internal, structural components of cells, creating a set of simulated cellular structures with novel mechanical properties, including one that acts like a red blood cell and another that mimics the soft, elastic behavior commonly found in novel synthetic materials called liquid crystal elastomers.

Environmental factors in the development of Parkinson's disease

The Parkinson's Institute today announced that new findings concerning the role of environmental factors in the development of Parkinson's disease will be reported at Asilomar (Pacific Grove, CA) as part of the final meeting of the Collaborative Centers for Parkinson's Disease Environmental Research (CCPDER).

Nicotine shown to enhance learning and memory

While nicotine is highly addictive, researchers have also shown the drug to enhance learning and memory, a property that has launched efforts to develop nicotine-like drugs to treat cognitive deficits in Alzheimer's and Parkinson's diseases, schizophrenia, and attention-deficit/hyperactivity disorder.

The rich are different !

Economists have postulated that people's perception of the value of financial gains decreases as they become richer, but scientists have not really been able to measure this change in 'marginal utility' in the laboratory, until now.

Research shows potential for treatment of diabetics in 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.

Stanford technique directly controls brain cell activity with light

Every thought, feeling and action originates from the electrical signals emitted by diverse brain cells enmeshed in a tangle of circuits.

White matter tracts in brain play a significant role in the rapid control of behavior

As wise as the counsel to "finish what you've started" may be, it is also sometimes critically important to do just the opposite -- stop.

Stroke damage in a brain region known as the putamen is strongly linked to motor neglect

Scientists have untangled two similar disabilities that often afflict stroke patients, in the process revealing that one may be treatable with drugs for Parkinson's disease.

New findings on hypoglycemic neuronal death

Treatment with insulin revolutionized the life of individuals with diabetes. However, because insulin acts to lower blood glucose levels, it can cause hypoglycemia (low levels of glucose in the blood), which, if prolonged, can lead to brain injury and coma.

Study explains exactly how exposure to lead during brain development produces learning deficits

A study of young adult rats by researchers from the Johns Hopkins Bloomberg School of Public Health provides evidence that explains exactly how exposure to lead during brain development produces learning deficits.

Halting neurogenesis improves working memory in mice

New research from Columbia University Medical Center may explain why people who are able to easily and accurately recall historical dates or long-ago events, may have a harder time with word recall or remembering the day's current events.

Scientists invent way to reversibly silence brain cells using pulses of yellow light

Scientists at the MIT Media Lab have invented a way to reversibly silence brain cells using pulses of yellow light, offering the prospect of controlling the haywire neuron activity that occurs in diseases such as epilepsy and Parkinson's disease.

Clearer picture of neuronal coding

The validity of a leading theory that has held a glimmer of hope for unraveling the intricacies of the brain has just been called into question.

Possible therapeutic target for Duchenne muscular dystrophy

In the April 1st issue of Genes & Development, Dr. Bruce Spiegelman (Dana Farber Cancer Institute) and colleagues identify a key genetic component of and possible therapeutic target for Duchenne muscular dystrophy.

Playing in the dirt to counter depression

Treatment of mice with a "friendly" bacteria, normally found in the soil, altered their behavior in a way similar to that produced by antidepressant drugs, reports research published in the latest issue of Neuroscience.

Iron nanoparticles exhibit toxic effects on neuronal cells

Researchers at UC San Diego have discovered that iron-containing nanoparticles being tested for use in several biomedical applications can be toxic to nerve cells and interfere with the formation of their signal-transmitting extensions.

Hearing-protection tablet helps soldiers defend against hearing loss

Soldiers exposed to the deafening din of battle have little defense against hearing loss, and are often reluctant to wear protective gear like ear plugs that could make them less able to react to danger.
