What are you scared of?

possibility of developing more efficient treatments for specific phobias or panic attacks, by targeting only the relevant region of the brain.

For their part, the EMBL scientists plan to probe these fears further.

"What we're interested in, in the long-run, is if these results represent a kind of mental state," says Cornelius Gross, who led the work. "If so, mice should be able to be in that state without expressing it in their behaviour do they re-live that fear, for example? These are not easy questions to ask in the mouse, but we're looking into them."

Gross's lab are also looking at how these different fears and the neural circuits that process them may have evolved. Working with Detlev Arendt's group at EMBL Heidelberg, they have discovered a similar brain region in a marine worm thought to closely resemble our ancestors from 600 million years ago. Now the team is exploring the possibility that this represents an ancestral core fear circuit that those ancestors handed down to us all, from worms to man.
