Most of us have been taught in school that the heart is constantly responding to "orders" sent by the brain in the form of neural signals. However, it is not as commonly known that the heart actually sends more signals to the brain than the brain sends to the heart! Moreover, these heart signals have a significant effect on brain function—influencing emotional processing as well as higher cognitive faculties such as attention, perception, memory, and problem-solving. In other words, not only does the heart respond to the brain, but the brain continuously responds to the heart.
Our new doc/clinic for Kid#2 did some really interesting heart test that was new to us. Lot of information from the heart that I hadn't realized previously.
