The brain could be said to be an ubiquitous organ. So much so, that in the heart there is what is called the intracardiac nervous system. Now, a team of researchers at Thomas Jefferson University in Philadelphia has created a 3D image of this heart’s brain in rats.

So far that was not possible because maintaining the integrity of the heart and even more, the integrity of the associated neural network was not possible. However, new technologies have made this feat a reality. Using knife-edge scanning microscopy, they looked at male and female rat hearts and produced high definition images that could later be used to build up a 3D model of the heart’s brain.
