The human brain is not wired to be logical or rational; in recently discovered neural science’s research it was determined that the dominant control and command center of our brain is hard-wired as an emotional decision-making tool and that logical is only a minor part of how our brain works and that while rational thinking is possible, it will always be dominated by our emotions. This explains how and why we may know that highly processed foods are dangerous to our health, but that we are easily influenced by the marketing of the food-processing corporations that have denuded our foods of all natural goodness and replaced it with chemicals and pesticides.
Our emotional brain can cope with massive amounts of new information – the perfect example is how we can read body-language and facial expressions. On the other hand, our rational, logical brain can only cope with a maximum of 5 – 7 pieces of information and this is a fact that has now been proven by science to be true. Dopamine is a chemical substance that gives us a sensation of pleasure and when something happens that pleases us by meeting our expectations of what we predicted; our neurons get a sudden release of the dopamine to reward us for anticipating things correctly. When we expect an outcome and it is not met, we don’t get the dopamine we hoped for, and we sense a feeling of remorse and regret.
The release of testosterone in our body also feeds back into our senses with the small release of dopamine. When we do a heavy and vigorous physical workout, the brain releases some testosterone that was in storage and it causes the used testosterone to be replaced when we sleep that night. These physiological processes fee back into our sense of well-being by means of a small release of dopamine. Many athletes complain of feeling irritable and not so well if they miss a work-out. They experience this because they did not get their anticipated dopamine release from an expected workout.
