Is it correct to say that heart and brain both are center of intellect ? Has there been any scientific study done to prove that like Brain, Heart also has intelligence and there are heart-signals just like we have brain-signals ? What is the current state of our understanding in this regard?

I am not a biology student so finding it difficult to find a relevant reference.

Thank you very much for your answers and comments.

    Except from metaphysics, which are no medical topic, where did you hear about this? – bummi Jan 8 '19 at 12:27

    Ahh Gregg Braden - he's crank and woo-meister who makes his living by selling new age word salad in books and seminar form. – motosubatsu Jan 8 '19 at 13:38

    @motosubatsu - woo-meister. heh, great turn of phrase. – JohnP Jan 8 '19 at 14:30

    I'm voting to close this question as off-topic because it is a basic biology/physiology topic. – DoctorWhom Jan 8 '19 at 16:14

The heart is not a center of intellect, it's a multi-chambered pump made primarily out of muscle.

There are however "heart signals", at least in a sense. The Sinoatrial Node is a specialized group of cells in the heart that produces regular action potentials across the cell membranes in the heart (causing the contractions that pump the blood) but this isn't an intellect or anything like that, just a regular cycle that provides the heart's sinus rhythm (essentially the "default" heart rate), the bodies autonomic nervous system (via the release of different chemicals) can influence the rate of these action potentials to raise or lower heart rate.

  • hmm, not a biology student, but isn't that any organ in the body can have signals? The electric signals are from the difference between inside and outside cell membrane, and thus collectively any organ should have a signal for itself? – Ooker Jan 9 '19 at 10:22
  • @Ooker Just because a cell happens to have a difference in charge across the cell membrane doesn't mean that charge has functionality. The only tissues in the body that use electrical charges for their functionality are muscle and nerve tissue. Most signaling in the body is chemical, not electrical. – Carey Gregory Jan 9 '19 at 19:17
  • I see. But let's take the electrical signal of the liver for example. Can it show how the liver is healthy or not? Chemical reactions are basically exchanging electrons, which is also a weak electrical signal. (I'm not really sure about this) – Ooker Jan 10 '19 at 2:21
