Researchers at the University of Alabama at Birmingham’s Magnetic Source Imaging Laboratory are studying the magnetic fields of neurons, using MEG (magneto-encephalography) scanners to learn more about the intricacies of brain pathology.
While other types of brain scans detail the geography of the brain or detect blood flow, the MEG scanners track the magnetic signals that neurons throw off as they communicate. “You can look at how the networks of the brain are talking to each other in real time,” said Greg Simpson, director of the Dynamic Neuroimaging Laboratory at the University of California at San Francisco.
The machines are designed to “measure the magnetic field pattern around the entire head and deduce from those patterns where the current flows are occurring within the brain,” said Eugene Hirschkoff, vice president of engineering at 4-D Neuroimaging, a MEG scanner manufacturer.
This allows scientists to study magnetic changes in the brain and figure out […]

Medical treatment for bomb tips
How medics in Iraq are treating citizens in exchange for intelligence: Medics treated an electrical burn on an Iraqi man injured doing home wiring. In return, he passed along a tip: Powerful local clan leaders have ordered a fresh crop of roadside bombs against U.S.-led forces. Published by KevinContinue reading: Medical treatment[...]
Implantable Nanowires for Continuous BP Monitoring
The American Heart Association has given high blood pressure the nickname “silent killer” for very good reasons. However, all of that could change with new implantable, biocompatible nanowires being developed at the Georgia Institute of Technology. Nanowires that produce a current during bending could one day be implanted into the[...]
Copper Door Handles to Beat MRSA?
If McGuyver was a physician, we think he’d love this low-tech solution for halting the spread of MRSA within hospitals. They have proved resistant to even the most powerful antibiotics. But hospital superbugs may finally have met their match - in copper door handles. Copper, used in medicines for 4,000 years, has[...]
Lasix and NSAIDs for Thoroughbred Race Horses
Barbaro was a young American thoroughbred horse that won the 2006 Kentucky Derby. On May 20, 2006, he ran in the Preakness Stakes as a heavy favorite, but he fractured three bones. Barbaro underwent surgery but he soon developed laminitis in his left rear leg. While his right leg eventually[...]
