Israeli researchers have published findings in mice that shed light on
stress reactions in people, and may help to explain the puzzling reactions in
military personnel described after the Gulf War.
Reporting in Nature, researchers from Hebrew University
(Jerusalem) and colleagues described molecular mechanisms involved in the brain's reaction
to stress in a mouse model. They showed that changes in gene expression occur after an
increase in activity at a type of receptor for the neurotransmitter acetylcholine.
