A team of researchers in California investigated the interaction between the brain and the heart. They found out that there are about 40,000 specialised neurons in the heart, forming a communication network.
It is as if the heart were a small brain, with a network of nerves and neurotransmitters similar to those found in the brain, which work to detect patterns in the body and warn the brain.
The heart has the largest electromagnetic field in the human body, about 4 meters in diameter. According to researchers, this electromagnetic field is affected by the electromagnetic field of other people, the planet Earth, the animals and plants and even those of other planets.
Feelings also affect this neuronal network in the heart. The Sensory Neurites are brain-like cells located in heart. They learn and memorise things independently.
Negative feelings, for instance, are a warning that the heart sends to the brain, decreasing the excretion of some hormones, which in turn affects our immune system. These signals also cause the heart to tell each cell what to do through nerve currents that reach the brain.
The study was based on how thought-triggered emotions affect the heart. The result of the research was accidental, astonishing scientists and opening new doors for us to understand how our can be emotionally affected (and how it affects us).
The so-called coherence of the heart is this communication between the heart and the brain, which occurs through this network of neurones sending characteristic nerve impulses.
