S.M., sometimes referred to as SM-046, is an American woman with a peculiar type of brain damage that physiologically reduces her ability to feel fear.First described by scientists in 1994, [1] she has had exclusive and complete bilateral amygdala destruction since late childhood as a consequence of Urbach–Wiethe disease.
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.
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.
The amygdala, located in the temporal lobe, is a key brain region involved in the conditioned fear response and contributes to the autonomic, hormonal, and behavioral factors associated with that response. According to studies by Coover, Murison, & Jellestad and Davis and LeDoux in 1992, when a dog's amygdala is damaged, it does not show fear ...
Fear is a conscious experience and occurs the same way as any other kind of conscious experience: via cortical circuits that allow attention to certain forms of brain activity. He argues the only differences between an emotional and non-emotion state of consciousness are the underlying neural ingredients that contribute to the state. [ 16 ]

An amygdala hijack is an emotional response that is immediate, overwhelming, and out of measure with the actual stimulus because it has triggered a much more significant emotional threat. [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 ...
