From the structure of the Gyri and Sulci, which we now already know from the „Tour: Brainpower & … I“, we zoom into the deeper layers: What do neurons look like? How does the information transfer in the brain take place? And how does our nervous system work? New findings confirm that important neuronal functions take place in the intestine and our eyes also consist of a so-called retinal structure. You will learn this and more during this guided tour.
