The Science behind Emotional Intelligence

The Case for an Emotional Brain
Emotions are not just a matter of the heart. Recent advances in research have shown that they are also a result of brain biochemistry. These conclusions come from neuroscience, evolution, medicine, psychology, and management. Emotional signals in the brain are felt throughout the body — in the gut, in the heart, in the head, in the neck, and so on. These sensations are important signals: If we learn to read them, they will help us make decisions and initiate action.

Most scientists believe that the control center of emotions in the brain is the limbic system, consisting of the amygdala, the hippocampus, and other structures in the mid-brain. The limbic system stores every experience we have from the first moments of life: impressions are stored in these areas long before we acquire the verbal or higher thinking abilities to put them into words. It is this vast warehouse of feelings and impressions that provides a context or meaning for those memories.

Messages are transmitted to the brain by neurons, traveling through an electrical transmission system. In the 1970s, however, scientists discovered that our bodies also contain a chemical system for transmitting messages. This system is based on chemicals called peptides, which have receptors in every cell of our bodies. These highly sensitive information substances are thought to be the chemical substrates of emotion, triggering impression memories throughout our lives. Our brains are linked to all our body systems, and it is these peptides that are responsible for the emotions we "feel" in various parts of our bodies.

This chemical transmission system just described is far, far older in evolutionary history than the electrical brain. In fact, many of the same information substances found in humans are found in one-celled animals. Their presence in the most basic as well as the most complex forms of life is a clear indication of their importance.
