Independent hypothalamic circuits for social and predator fear

Nat Neurosci. 2013 Dec;16(12):1731-3. doi: 10.1038/nn.3573. Epub 2013 Nov 10.

Abstract

The neural circuits mediating fear to naturalistic threats are poorly understood. We found that functionally independent populations of neurons in the ventromedial hypothalamus (VMH), a region that has been implicated in feeding, sex and aggression, are essential for predator and social fear in mice. Our results establish a critical role for VMH in fear and have implications for selective intervention in pathological fear in humans.
