In fear conditioning, the main circuits that are involved are the sensory areas that process the conditioned and unconditioned stimuli, certain regions of the amygdala that undergo plasticity (or long-term potentiation) during learning, and the regions that bear an effect on the expression of specific conditioned responses.
Fear is affected by cultural and historical context. For example, in the early 20th century, many Americans feared polio, a disease that can lead to paralysis. [15] There are consistent cross-cultural differences in how people respond to fear. [16] Display rules affect how likely people are to express the facial expression of fear and other ...
Pavlovian fear conditioning is a behavioral paradigm in which organisms learn to predict aversive events. [1] It is a form of learning in which an aversive stimulus (e.g. an electrical shock) is associated with a particular neutral context (e.g., a room) or neutral stimulus (e.g., a tone), resulting in the expression of fear responses to the originally neutral stimulus or context.
Conditioned fear is the framework used to explain the behavior produced when an originally neutral stimulus is consistently paired with a stimulus that evokes fear. The amygdala represents a core fear system in the human body, which is involved in the expression of conditioned fear.

An experiment with S.M. revealed no fear in response to exposure and handling of snakes and spiders (including tarantulas), a walk through a haunted attraction (Waverly Hills Sanatorium, specifically), or fear-inducing film clips (e.g., The Blair Witch Project, The Shining, and The Silence of the Lambs), eliciting instead only interest, curiosity, and excitement, though she expressed emotions ...
