Researchers have shown that the human heart has a sophisticated neurological system and functions essentially on its own, sometimes referred to as a "little brain."
Recent studies on zebrafish have shown that the heart is surrounded by a very complex network of neurons that interpret brain signals to control cardiac rhythm in addition to acting as a pacemaker.
By employing sophisticated methods like as electrical analysis and RNA profiling, scientists were able to identify a variety of cell types that resembled those involved in regular body processes. By focusing on the heart's distinct neural system, this ground-breaking discovery reveals the heart's complex self-regulation and creates new therapeutic opportunities for disorders like arrhythmias.
