Child and adult brains structured differently
Brain's organization switches as children become adults
May 14,
2009 -- Any child confronting an outraged parent demanding to know "What were you thinking?" now has a new response: "Scientists have discovered that my brain is organized differently than yours." But all is not well for errant kids. The same new study also provides parents with a rejoinder: While the overarching organization scheme differs, one of the most important core principals of adult brain organization is present in the brains of children as young as 7.

Brain Scientists Misled By Squid
NPR Morning Edition
and 1 others
Sept. 11,
2009 -- Jon Hamilton reports on a recent German study in Science that says that for more than 50 years, scientists who study the brain have been misled by squid. They did experiments on squid nerve cells thinking that those cells were good models for the human nervous system.
WUSTL radiology professor Marcus Raichle, who does brain imaging studies, says, "There is always this tendency that if you're working in an area and your experiments are working well and you're getting good data, to not think of the larger context in which this is occurring."

Novel Technique Changes Lymph Node Biopsy, Reduces Radiation Exposure
ScienceDaily.com
Jan. 14,
2009 -- Information obtained from a new application of photoacoustic tomography (PAT) is worth its weight in gold to breast cancer patients. The work of WUSTL biomedical engineering researchers Lihong Wang and Younan Xia, supported by the NIH, can minimize invasive surgical lymph node biopsy procedures to determine if breast cancer has metastasized and reduce the patient's exposure to radioactivity.

You're Checked Out, but Your Brain Is Tuned In
The New York Times
and 8 others
Aug. 5,
2008 -- Boredom is more than a mere flagging of interest or a precursor to mischief.
Using brain-imaging technology, neuroscientists have found that the brain is highly active when disengaged, consuming only about 5 percent less energy in its resting "default state" than when involved in routine tasks, according to WUSTL radiology professor Mark Mintun.
