The most evolved layer of the brain, the prefrontal cortex, gets activated when we self reflect on questions like, "Who Am I?" and "How do I or can I make a difference of the world?", writes Dr. Susan Taylor on Your Meditating Brain.
The limbic system, is cerebral structure of the brain linked with emotions and other functions including autonomic regulation and homeostasis. The autonomic nervous system is a control system which regulates heart rate, digestion, respiratory rate, and other functions. It's the primary mechanism in control of the fight-or-flight response.
Certain thought patterns like negative thoughts and emotions can disrupt autonomic self-regulation and take us out of our natural state of balance, short-circuiting our mind-body connection. When our mind-body connection is disrupted, bad habits tell the body what to do. The wrong signals are sent, and as the body reacts by getting fatter, more imbalanced, and ultimately sick.
Through systematic meditation and the focused awareness we can become aware of our thought patterns. With awareness, comes the ability to change them.
Our meditation practice can strengthen and optimize these systems and functions by training our thoughts and emotions to be positive, thereby minimising disruption and promoting homeostasis.
