How Fear Persists in the Mouse Brain

When a mouse senses a threat, neurons in the ventromedial hypothalamus become activated and remain active for ten seconds after the threat is removed. Fear responses could be induced by artificially stimulating these neurons. Artificially silencing the neurons reduced fear behavior.
