Brain – The Three Pound Universe
Brain is an intelligent organ that grows by interaction with the outside world. It is capable of continually adapting. Even in old age, it can grow new neurons. Although diseases frequently lead to cognitive decline, inactivity – both physical and mental – is the most common cause of age-related loss of functioning. In other words, use it or lose it.
Throughout life, your networks reorganize themselves in response to new stimuli and experiences. This is what stimulates brain cells to grow and connect with each other in complicated ways. This is the structural basis of your brain’s memorizing power and thinking ability. As a product of its environment, your “three pound universe” is essentially an internal reflection of your interaction with the external world.
Plasticity is the most important quality of the human brain – it is the tendency to shape itself according to experience.. Plasticity creates neural networks that give you adaptability and versatility. Without plasticity you won’t be able to survive in the fast changing world. Lack of plasticity means rigidity – rigidity of attitudes, likes and dislikes as well as of preferences and prejudices. A healthy human brain is highly flexible and most moldable. Mental rigidity also shows up in rigid body.
The health of your brain vitally depends upon your mental and physical health. Physical health means well nourished muscles, bones and organs as well as strong immune system. Mental health vitally depends on your emotional health. It implies freedom from emotional wounds, set of healthy attitudes and beliefs, and a relaxed and confident mind.
