The brain and heart have various types of communication pathways. We often focus on the reasoning process that goes on in the brain but the heart as an organ has its own type of intellect. The heart communicates to the brain: neurologically (through nerves), biochemically (through hormones and neurotransmitters), biophysically (through pressure waves), and energetically (through an electromagnetic field). We think of the brain as having an electromagnetic field but the heart actually has a larger electromagnetic field than the brain.
