behavioral inhibition system (BIS)
Brain circuit in the limbic system that responds to threat signals by inhibiting activity and causing anxiety.
fight/flight system (FFS)
Brain circuit in animals that when stimulated causes an immediate alarm-and-escape response resembling human panic.

panic disorder (PD)
Recurrent, unexpected panic attacks accompanied by anxiety about future attacks.
agoraphobia
Anxiety about being in places or situations from which escape might be difficult in the event of panic-like symptoms or other unpleasant physical symptoms.
panic control treatment (PCT)
Cognitive-behavioral treatment for panic attacks, involving gradual exposure to feared somatic sensations and modification of perceptions and attitudes about them.
specific phobia
Unreasonable fear of a specific object or situation that markedly interferes with daily life functioning.
blood-injury-injection phobia
