The researchers put themice in a labyrinth space to observe their stress behavior patterns. They found that in open, brightly lit places, mice felt stressed and panicked and found ways to escape, while drugs or genes inhibited the production of certain proteins in the amygdala of the mice brain. they will no longer have similar stress behavior patterns in the same area. The researchers concluded that the activity of this protein determines the stress resistance of mice, which in turn determines its stress behavior pattern.
If the mice feels nervous in an open, brightly lit place, the function of the amygdala to produce this protein is not inhibited can be derived from this.
