Washington, Mar 10 : Researchers from University of Southern California have identified an area of hypothalamus in the brain, which is key to animals'' fear of territorial rivals and predators.

Brain's amygdala region has long been studied by researchers as the region of fear. However, the new study has shown that primal fear responses do not depend on the amygdala, but on an obscure corner of the primeval brain.
