A new study from the Salk Institute for Biological Studies has identified a brain circuit that slows the breath to calm the mind.

Before Jonas Salk developed the first successful polio vaccine in the mid-1950s, the disease killed or paralyzed more than half a million people around the world each year.

"His whole commitment was protecting the population from infectious diseases," Salk said.

Neuroscientists at the Salk Institute for Biological Studies in La Jolla have identified a brain pathway that instantly deflates anxiety.

More immediately, the findings will inform the Salk Harnessing Plants Initiative's mission to create optimized crops that simultaneously fight and withstand the threat of climate change.
