Heart Brain: There are many secrets hidden in the heart. Our heart is made of muscular tissue, which is located slightly to the left in the middle of the chest. It is triangular in shape, 13 cm long and 9 cm wide. The heart pushes and pumps blood through the body. There are 4-5 thousand neurons in the heart, which help it to beat and maintain blood circulation.
Earlier it was believed that the brain controls the body and gives orders to every organ. It also controls the heart by giving signals, but a study published in Nature Communications found that the heart is the master of its own will. He does not take orders from the mind but gives them.
heart nervous system
Researchers from Karolinska Institutet in Sweden and Columbia University in New York said that there is a nervous system inside the heart, which is called intrinsic cardiac nervous system, which acts as the brain of the heart. Due to which it not only keeps sending messages to the brain continuously, but the brain also accepts them.
Neuron mimics pacemaker
Researchers examined zebrafish, whose heart’s structure and functioning are similar 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 discovered different types of neurons. These neurons communicate using several different neurotransmitters, such as acetylcholine, glutamate, and serotonin, which provide signals to control heartbeat.

How important is the brain for the heart?
This system helps the heart to meet the needs of the body. To keep the heart beating properly, it is very important to have a heart brain. However, the heart mind does not have the ability to think. The intrinsic cardiac nervous system is a complex system made up of neurons that works similar to a computer chip. A research has revealed that the intrinsic cardiac nervous system has functions like both short term and long term memory.
