The heart also has its own mind, it is master of its own will – study

Heart Brain: There are many secrets hidden in the heart. Our heart is made up of muscle tissue located slightly to the left, in the middle of the chest. It is triangular in shape, measures 13 cm long and 9 cm wide. The heart pushes and pumps blood throughout the body. There are 4 to 5,000 neurons in the heart that help it beat and maintain blood flow.

Previously, it was believed that the brain controlled the body and gave orders to each organ. It also controls the heart by emitting signals, but a study published in Nature Communications found that the heart is master of its own will. He does not receive orders from the spirit but gives them.

cardiac nervous system

Researchers from Karolinska Institutet in Sweden and Columbia University in New York said there is a nervous system inside the heart, called the intrinsic cardiac nervous system, which acts as the brain of the heart. Thanks to this, not only does it continue to send messages to the brain continuously, but the brain also accepts them.

A neuron imitates a pacemaker

The researchers looked at zebrafish, whose heart is similar in structure and function to the human heart. A specific area of ​​the heart was focused on the sinoatrial plexus (SAP), which acts as the pacemaker of the heart. Scientists have discovered different types of neurons. These neurons communicate using several different neurotransmitters, such as acetylcholine, glutamate, and serotonin, which provide signals to control heart rate.

How important is the brain to the heart?

This system helps the heart meet the needs of the body. For the heart to continue beating properly, it is very important to have a heart-brain. However, the mind of the heart does not have the capacity to think. The intrinsic cardiac nervous system is a complex system made up of neurons that functions like a computer chip. Research has found that the intrinsic cardiac nervous system performs functions such as short-term and long-term memory.
