Researchers put mice in a labyrinth space to observe their stress behavior patterns. They found that in open and bright places, mice felt stressed and panicked and tried to escape; through drugs or After genetically inhibiting the function of the mouse amygdala to produce a certain protein, they will no longer have similar stress behavior patterns in the same area. The researchers concluded that the activity of this protein determines the mice's resistance to The ability to stress, which in turn determines its stress behavior pattern. From this we can infer:. ['If the mouse is panicking in an open, brightly lit place, its function of producing this protein in the amygdala of the brain is not inhibited.', 'If the mouse is not disturbed in an open, brightly lit place, its function of producing this protein in the amygdala of the brain is inhibited.', 'Only when the function of producing this protein in the amygdala of the mouse is inhibited, the mouse will not be disturbed in the open and bright place.', "If the function of the mouse's amygdala to produce this protein is not inhibited, the mouse will panic in the open and bright place."]
