Luckily, neuroplasticity shows that we can change our magnification of negative memories and experiences and rewire our brains for a more positive response. Brain scans prove that with meditation practiced regularly, the size of amygdala actually reduces, making us overreact less often. The bigger is the amygdala, the more aggressive behavior an individual demonstrates, the more fear they experience, and the more stress is present in their lives.
While decreasing amygdala, meditation, and mindfulness help to increase another part of the limbic system, called insula. This brain region is responsible for empathy and emotions which cause positive feelings. Hence, the emotional and stress response are worked from the two frontiers out with meditation – minimizing the negative influence of emotions and increasing the positive one.
