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.
[5] [7] For example, studies with Maria Morgan in the 1990s implicated the medial prefrontal cortex in the extinction (psychology) of responses to threats [8] and paved the way for understanding how exposure therapy reduces threat reactions in people with anxiety by way of interactions between the medial prefrontal cortex and the amygdala.
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 ...
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.
Though support exists for using the BAI with high-school students and psychiatric inpatient samples of ages 14 to 18 years, [26] the recently developed diagnostic tool, Beck Youth Inventories, Second Edition, contains an anxiety inventory of 20 questions specifically designed for children and adolescents ages 7 to 18 years old.

In economic theory, human decision-making is often modeled as being devoid of emotions, involving only logical reasoning based on cost-benefit calculations. [3] In contrast, the somatic marker hypothesis proposes that emotions play a critical role in the ability to make fast, rational decisions in complex and uncertain situations.
The amygdala plays a key role in emotional processing especially fear, and amygdala function appears to be emotionally lateralized. When people are shown fearful faces the left amygdala and left periamygdaloid cortex increase in activation. There also appears to be a greater increase in neural activity in the left amygdala corresponding to an ...
The amygdala is associated with emotional processing, particularly for the emotion of fear, as well as memory. It is important in processing emotional reactions towards novel or unexpected stimuli and the induction of exploratory behavior. This suggests a connection between curiosity levels and the amygdala.
