Scientists uncover key developmental mechanisms of the amygdala

For the first time, scientists at Children's National Medical Center have successfully identified a key developmental program for the amygdala-the part of the limbic system that impacts how the brain creates emotional memories and responses.

Discovery of mechanism that may explain Parkinson's and other neurological disorders

Studying just eight families worldwide, the international team of researchers have discovered a genetic defect that results in profound depression and parkinsonism in a disorder known as Perry syndrome.

Discovery of new molecule in blood-pressure control system

Researchers at Oregon Health & Science University's School of Dentistry have discovered that the nerve cells controlling heart rate and blood pressure synthesize a molecule known to be critically important for proper nervous system growth.

Growth of new brain cells requires 'epigenetic' switch

New cells are born every day in the brain's hippocampus, but what controls this birth has remained a mystery.

New hope for leptin as a solution to obesity

The discovery more than a decade ago of leptin, an appetite-suppressing hormone secreted by fat tissue, generated headlines and great hopes for an effective treatment for obesity.

Stem cells from human testes can change into other body tissues

Scientists at the Stanford University School of Medicine and at UC-San Francisco have succeeded in isolating stem cells from human testes.

Collagen VI protects brain cells against amyloid-beta proteins

Scientists from the Gladstone Institute of Neurological Disease (GIND), UCSF, and Stanford have discovered that a certain type of collagen, collagen VI, protects brain cells against amyloid-beta proteins, which are widely thought to cause Alzheimer's disease (AD).

A novel glioblastoma mouse model developed

Researchers at the Salk Institute for Biological Studies have developed a versatile mouse model of glioblastoma-the most common and deadly brain cancer in humans-that closely resembles the development and progression of human brain tumors that arise naturally.

Risk takers do so because their brains are less able to process dopamine

According to scientists risk takers and drug abusers behave the way they do because their brains are less able to process dopamine.

Matrix fragments trigger fatal excitement

Shredded extracellular matrix (ECM) is toxic to neurons. Chen et al. reveal a new mechanism for how ECM demolition causes brain damage. The study will appear in the December 29, 2008 issue of The Journal of Cell Biology (www.jcb.org).

Patient-derived induced stem cells retain disease traits

The dying cells - the same type lost in patients with the devastating neurological disease spinal muscular atrophy - confirmed that the University of Wisconsin-Madison stem cell biologist had recreated the hallmarks of a genetic disorder in the lab, using stem cells derived from a patient.

Carbon nanotubes show promise in emerging field of neuro-engineering and neuroprosthetics

Research done by scientists in Italy and Switzerland has shown that carbon nanotubes may be the ideal "smart" brain material.

How mirror neurons allow us to learn and socialize by going through the motions in the head

The old adage that we can only learn how to do something by trying it ourselves may have to be revised in the light of recent discoveries in neuroscience.

Study looks at brain and movement planning

When you first notice a door handle, your brain has already been hard at work. Your visual system first sees the handle, then it sends information to various parts of the brain, which go on to decipher out the details, such as color and the direction the handle is pointing. As the information about an object is sent further along the various brain pathways, more and more details are noticed-in that way, a simple door handle turns into a silver-plated-antique-style-door-handle-facing-right.

SRS microscopy helps track molecules and drugs in live cells

A new type of highly sensitive microscopy developed by researchers at Harvard University could greatly expand the limits of modern biomedical imaging, allowing scientists to track the location of minuscule metabolites and drugs in living cells and tissues without the use of any kind of fluorescent labeling.
