/əˈmɪɡ.də.lə/ · noun
(neuroanatomy) Each one of the two regions of the brain, located as a pair in the medial temporal lobe, believed to play a key role in processing emotions, such as fear and pleasure, in both animals and humans..
There is experimental evidence showing that cortisol restrains the intensity and duration of the emergency reaction to stress, and catecholamines have been shown to enhance emotional memory in the amygdala (see subsection on "Noradrenaline"). Thus, individuals lacking cortisol would overstore traumatic memories .
Cognitive scientists distinguish between normal risk-assessment decisions, which activate the reward-prediction regions of the brain, and decisions made amid extreme uncertainty, which generate activity in the amygdala.
In the study, led by Ryota Kanai of the University College London, people who identified themselves as liberals generally had a larger anterior cingulate cortex — a comma-shaped region near the front of the brain that is involved in decision-making. By contrast, those who identified as conservatives had larger amygdalas — almond-shaped structures that are linked with emotional learning and the processing of fear.
A decreased amygdala response, in other words, may help explain the “slippery slope” of lying, said Sharot, one of the authors of “The Human Brain Adapts to Dishonesty,” just published in the journal Nature Neuroscience.
Use amygdala when its meaning, tone and grammar fit the full sentence. A synonym is not always a direct replacement.
