Fear is an unpleasant emotion that arises in response to perceived dangers or threats. Fear causes physiological and psychological changes. It may produce behavioral reactions such as mounting an aggressive response or fleeing the threat, commonly known as the fight-or-flight response. Extreme cases of fear can trigger an immobilized freeze ...
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.
It may also be called "conditioned suppression" or "conditioned fear response (CFR)." [1] It is an "emotional response" that results from classical conditioning, usually from the association of a relatively neutral stimulus with a painful or fear-inducing unconditional stimulus. As a result, the formerly neutral stimulus elicits fear.
This emotional response conditions the individual to avoid fear-inducing stimuli and more importantly, to assess threats in the environment. The right hemisphere is also linked to declarative memory , which consists of facts and information from previously experienced events and must be consciously recalled.
Emotional Responses: Appraisal tendencies influence emotional responses to situations. For instance, individuals with a tendency to appraise situations as threatening may consistently experience fear or anxiety in response to a range of situations perceived as threats.

McNally explains, "fear is represented in memory as a network comprising stimulus propositions that express information about feared cues, response propositions that express information about behavioral and physiologic responses to these cues, and meaning propositions that elaborate on the significance of other elements in the fear ...

Fear and anxiety often can overlap but this distinction can help identify subtle differences between disorders, as well as differentiate between a response that would be expected given a person's ...

[1] The term, coined by Daniel Goleman in his 1996 book Emotional Intelligence: Why It Can Matter More Than IQ , [ 2 ] is used by affective neuroscientists ...
