Summary

Demonstrating how genes influence behavioral traits has been much more difficult than tracing the lineage of physical characteristics. Now a study on page 400 has shown that people with different versions of a single gene have different patterns of brain activity in response to emotion-laden stimuli. The findings demonstrate that individual genes can contribute to how the brain interprets its environment, researchers say.
