Vigilance involves the activation of orexinergic neurons in the lateral hypothalamus (LH-ox). Here the authors report the functional role of a monosynaptically connected circuit with orexinergic neurons connected to noradrenergic neurons in the locus coeruleus which target lateral amygdala neurons and enhance fear expression and generalization.
