UCLA scientists report link between traumatic brain injury, post-traumatic stress disorder
Date:2/15/2012

neurotransmitters that promote learning," said Maxine Reger, a UCLA graduate student of psychology in Fanselow's laboratory and the lead author of the study.

"This finding suggests that brain injury leaves the amygdala in a more excitable state that readies it for acquiring potent fear," Fanselow said.

The research was funded by the National Institutes of Health, the U.S. Department of Defense and the UCLA Brain Injury Research Center.

Co-authors of the study were David Hovda, a professor of neurosurgery and of molecular and medical pharmacology at the David Geffen School of Medicine at UCLA and director of the UCLA Brain Injury Research Center; Andrew Poulos, a postdoctoral fellow in Fanselow's laboratory; Floyd Buen, a former graduate student in Hovda's laboratory; and Christopher Giza, an associate professor of neurosurgery at the Geffen School of Medicine.

The research was a collaboration between Fanselow's laboratory, which studies neural mechanisms of anxiety disorders, and Hovda's laboratory, which investigates brain injury.

"One of UCLA's great strengths is the spirit of collaboration that allows scientists from very different departments to combine their very different expertises to answer important but difficult questions," Fanselow said.
