OMV-SfN’s 2010 Winter Meeting will be held Friday, January 29, from 10 a.m. – 12 noon at the University of Cincinnati’s Metabolic Diseases Institute/Genome Research Institute (2180 E. Galbraith Rd., Cincinnati 45237) in the Building A lecture room.
The meeting will begin with four 20-minute research presentations, one from each of OMV-SfN’s four participating institutions. The business meeting will follow and James Eliassen, Ph.D., will be inducted as 2010 chapter president. Scientific presentations include:
- Gale Kleven, Ph.D. (Wright State University)
MR Spectroscopy and Behavioral Epigenesis
- Jennifer J. Quinn, Ph.D. (Miami University)
Neurobiological mechanisms of long-term memory consolidation and stabilization
- Yvonne Ulrich-Lai, Ph.D. (University of Cincinnati)
Stress-relieving properties of palatable foods

According to NPR: “A recent study led by neuroscientist Susan Tapert of the University of California, San Diego compared the brain scans of teens who drink heavily with the scans of teens who don’t.
“Tapert’s team found damaged nerve tissue in the brains of the teens who drank. The researchers believe this damage negatively affects attention span in boys, and girls’ ability to comprehend and interpret visual information.
For the study, published last month in the journal Psychology of Addictive Behaviors, Tapert looked at 12- to 14-year-olds before they used any alcohol or drugs. Over time, some of the kids started to drink, a few rather heavily — consuming four or five drinks per occasion, two or three times a month — classic binge drinking behavior in teens.
Comparing the young people who drank heavily with those who remained non-drinkers, Tapert’s team found that the binge drinkers did worse on thinking and memory tests. There was also a distinct gender difference. Read more.

Researchers at the University of Minnesota report that measuring fluctuations in the brain’s magnetic activity as neurons fire in synchrony, a method known as synchronous neural interactions (SNI), may provide an effective approach for diagnosing post-traumatic stress disorder (PTSD). Their work is reported in the Journal of Neural Engineering. According to BBC News:
The brain’s signals are effectively a symphony of electrical impulses, which in turn drive tiny magnetic fields.
Researchers have measured and mapped these fields, in a pursuit known as magnetoencephalography, since the late 1960s. It has already been used to diagnose tinnitus, and can even predict when people will make mistakes.
Apostolos Georgopoulos, at the University of Minnesota in the US, developed the synchronous neural interactions (SNI) approach as a means to mathematically untangle the myriad signals that magnetoencephalography produces. Read more.
