And while there are two units (left and right sides of the brain) to the amygdala, it is more often discussed as if it were one organ, so the singular term "amygdala", and the common usage plural "amygdalas," not the Latin plural "amygdalae" is used here and throughout most of the medical literature. (typepad.com)
But the amygdale is not a part of the conscious brain. (typepad.com)
The study of the function of the amygdale has helped resolve one of the great debates in neuroscience over the last 250 years: Whether the Body (in this case, the amygdala and the brain) governed the Mind (in this case, the sense of consciousness, self-awareness, thought processing, learning and memory), or whether these were two truly distinct operations. (typepad.com)
The amygdala may very well do this by helping the brain identify salient points of new inputs (whether they have red or green flags indicating either danger or reward) and to prioritize them by the use of the "magnitude dial" of the amygdale (important enough to pay close attention, or not so important or threatening and therefore, something to ignore).
