(Tom’s note: Please bear in mind these researchers do not take into account that you are a spiritual being, they think of you only as a body, so they are missing the key element in the big picture, the elephant in the china shop if you will. So in the article when they refer to structure, accept their label of the brain but when they refer to function, they would be more accurate to refer to the mind or you, the spirit.)
A 2013 study on mice published in the journal Brain, Structure and Function used differed types of noise and silence and monitored the effect the sound and silence had on the brains of the mice. The silence was intended to be the control in the study but what they found was surprising. The scientists discovered that when the mice were exposed to two hours of silence per day they developed new cells in the hippocampus. The hippocampus is a region of the brain associated with memory, emotion and learning.
