Neuroscience of the Heart

The video explores the heart's function, focusing on the intracardiac nervous system (ICN), a mini brain that helps regulate heartbeats. A 3D model of a rat heart was created using a knife-edge scanning microscope, revealing the ICN's neuron clusters. This model aids in understanding the ICN's role and could lead to new treatments for heart conditions.
