Abstract: &NA; It has been established that chemical stimulation of the inferior colliculus (IC) of laboratory animals evokes fear‐related defensive responses, which are considered panic attack‐like behaviours. In addition, there is evidence that defensive reactions provoked… read more here.

Abstract: The presence of a nearby but not immediate threat often produces a freezing response, both in animals and in humans. Freezing is associated with bradycardia (slowed heart rate) via the parasympathetic nervous system. However, the… read more here.
