MIT model helps researchers 'see' brain development
04-09-2007 · EurekAlert!Large mammals -- humans, monkeys and even cats -- have brains with a somewhat mysterious feature: the outermost layer has a folded surface. Understanding the functional significance of these folds is one of the big open questions in neuroscience. Now a team led by MIT, Massachusetts General Hospital and Harvard Medical School researchers has developed a tool that could aid such studies by helping researchers "see" how those folds develop and decay in the cerebral cortex.

- Preclinical study links gene to brain aneurysm formation
08-07-2007 · EurekAlert!
University of Cincinnati neurovascular researchers have identified a gene that -- when suppressed or completely absent -- may predispose a person to brain aneurysms. Todd Abruzzo, MD, and his colleagues demonstrated that "knocking out" a gene known as endothelial nitric oxide synthase in an animal model led to intracranial aneurysm formation in 33 percent of study subjects. Scientists say this suggests that the gene may play an important role in the development of intracranial aneurysms.

- Using fMRI to study brain development
11-30-2007 · EurekAlert!
Using fMRI to study early brain development requires learning more about the fMRI signal in the developing brain. MIT neuroscientists studying rats found the signal changes during first few weeks of life in relation to actual brain activity. Correcting for those changes, the researchers could monitor the development of the rat brain. The findings also identified a key player in the age-related changes in neurovascular coupling that gives rise to the BOLD signal.

- MIT: 'Micro' livers could aid drug screening
11-18-2007 · EurekAlert!
MIT researchers have devised a novel way to create tiny colonies of living human liver cells that model the full-sized organ. The work could allow better screening of new drugs that are potentially harmful to the liver and reduce the costs associated with their development.

- Mimicking how the brain recognizes street scenes
02-07-2007 · EurekAlert!
Scientists in Tomaso Poggio's laboratory at the McGovern Institute for Brain Research at MIT developed a computational model of how the brain processes visual information and applied it to a complex, real world task: Recognizing the objects in a busy street scene. The researchers were pleasantly surprised at the power of this first application of a biologically inspired computer model for artificial vision, which has many potential practical applications.

- Missing protein may be key to autism
12-05-2007 · Massachusetts Institute of Technology (MIT)
A missing brain protein that helps in the development of synapses may be one of the culprits behind autism and other brain disorders, according to researchers at MIT's Picower Institute for Learning and Memory.

- Fat fish put obesity on the hook
06-18-2007 · EurekAlert!
Everyone knows that eating lean fish helps slim waistlines, but researchers have found a new way fish can help eliminate obesity. In a study to be published in the July 2007 print issue of the FASEB Journal, researchers describe the first genetic model of obesity in a fish. Having this model should greatly accelerate the development of new drugs to help people lose weight and keep it off.

- OHSU School of Dentistry team discovers potential new target for treating craniofacial pain problems
10-30-2006 · EurekAlert!
Researchers at Oregon Health and Science University's School of Dentistry have uncovered an interaction between two proteins in the nerve cells that carry pain information from the head and neck to the brain. The finding could play a significant role in the development of therapies to cure migraines and other craniofacial pain conditions like TMJ disorder.
