" It is interesting to note that although our limbic system functions throughout our lifetime, it does not mature. As a result, when our emotional "buttons" are pushed, we retain the ability to react as though we were a two year old, even when we are adults. As our higher cortical cells mature and become integrated in complex networks with other neurons, we gain the ability to take "new pictures" of the present moment. When we compare the new information of our thinking mind with the automatic reactivity of our limbic mind, we can reevaluate the current situation and purposely choose a more mature response. "
