The study offers insight into economic behavior, and also into the role of the brain's amygdalae
, two almond-shaped clusters of tissue located in the medial temporal lobes.
Shown in research to perform a primary role in the processing and memory of emotional reactions, the amygdalae
are considered part of the limbic system.
DENVER - The common denominator between joint hypermobility and panic disorder might lie in the significantly enlarged amygdalae
shown to be present in individuals with lax joints in a recent study.
Functional imaging studies showed increased activation of the amygdalae
after fear stimuli in healthy volunteers.
When in the fMRI scanner, subjects could not see, feel, or hear the experimenter; nevertheless, their amygdalae
lit up when they believed the experimenter to be close by.
