Human brain in the coronal orientation. Amygdalae are shown in dark red. The amygdala (/ ə ˈ m ɪ ɡ d ə l ə /; pl.: amygdalae / ə ˈ m ɪ ɡ d ə l i,-l aɪ / or amygdalas; also corpus amygdaloideum; Latin from Greek, ἀμυγδαλή, amygdalē, 'almond', 'tonsil' [1]) is a paired nuclear complex present in the cerebral hemispheres of vertebrates.
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 ...
Besides memory, the amygdala also seems to be an important brain region involved in attentional and emotional processes. First, to define attention in cognitive terms, attention is the ability to focus on some stimuli while ignoring others. Thus, the amygdala seems to be an important structure in this ability.
The ventromedial prefrontal cortex (vmPFC) is a part of the prefrontal cortex in the mammalian brain.The ventral medial prefrontal is located in the frontal lobe at the bottom of the cerebral hemispheres and is implicated in the processing of risk and fear, as it is critical in the regulation of amygdala activity in humans.

This procedure allowed him to follow the flow of information about a stimulus through the brain as it comes to control behavioral responses by way of sensory pathways to the amygdala, and gave rise to the notion of two sensory roads to the amygdala, with the "low road" being a quick and dirty subcortical pathway for rapid activity behavioral ...
The amygdala and temporal lobes have been implicated in the pathology of Klüver–Bucy syndrome as well, leading to docility, hyperorality, and in some rare cases hypersexuality. Unlike patients of social-emotional agnosia, people with Klüver–Bucy syndrome also tend to demonstrate visual agnosia (inability to recognize visual stimuli) and ...
The amygdala is thought to be involved in processing biologically relevant stimuli and in emotional long-term memory, particularly those associated with fear, and both PET and MRI scans have shown a correlation between amygdala activation and episodic memory for strongly emotional stimuli. [14]
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.
