From Joseph Chilton Pierce, author of “The Crack in the Cosmic Egg”:

Molecular biologists have discovered that the heart is the body’s most important endocrine gland. In response to our experience of the world, it produces and releases a major hormone, ANF that profoundly affects every operation in the limbic structure, or what we refer to as the “emotional brain.” This includes the hippocampal area where memory and learning take place, and also the control centers for the entire hormonal system.

 

Neurocardiologists have found that 60 to 65% of the cells of the heart are actually neural cells, not muscle cells as was previously believed. They are identical to the neural cells in the brain, operating through the same connecting links called ganglia, with the same axonal and dendritic connections that take place in the brain, as well as through the very same kinds of neurotransmitters found in the brain.

 

…in other words, there is a “brain” in the heart, whose ganglia are linked to every major organ in the body, to the entire muscle spindle system that uniquely enables humans to express their emotions. About half of the heart’s neural cells are involved in translating information sent to it from all over the body so that it can keep the body working as one harmonious whole. And the other half make up a very large, unmediated neural connection with the emotional brain in our head and carry on a 24-hour-a-day dialogue…

 

The heart responds to messages sent to it from the emotional brain, which has been busy monitoring the interior environment of dynamic states such as the emotions and the auto-immune system, guiding behavior, and contributing to our sense of personal identity. The emotional brain makes a qualitative evaluation of our experience of this world and sends that information instant-by-instant down to the heart. In return, the heart exhorts the brain to make the appropriate response….

 

…Meanwhile, biophysicists have discovered that the heart is also a very powerful electromagnetic generator. It creates an electromagnetic field that encompasses the body and extends out anywhere from eight to twelve feet away from it. It is so powerful that you can take an electrocardiogram reading from as far as three feet way from the body. The field the heart produces is holographic, meaning that you can read it from any point on the body and from any point within the field. The intriguing thing is how profoundly this electromagnetic field affects the brain. All indications are that it furnishes the whole radio wave spectrum from which the brain draws its material to create our internal experience of the world.

 

…we now know that the radio spectrum of the heart is profoundly affected by our emotional response to our world. Our emotional response changes the heart’s electromagnetic spectrum, which is what the brain feeds on. Ultimately, everything in our lives hinges on our emotional response to specific events.
