# Folgezettel Heterarchy Neuron allows you to organically build a Heterarchy out of your Zettelkasten over time. When a zettel links (see linking) to another, it "branches off"[^1] to that zettel ... using `[[[...]]]` (i.e, three brackets, instead of two). A ⇒ Folgezettel heterarchy differs from a traditional "category tree" in two key ways: * It is built *organically* over time based on the connections formed, instead of being pre-defined. * A note can have *multiple* parents. The heterarchy is displayed in the following places * z-index: Full folgezettel heterarchy of the zettelkasten. * [5e41fd32]: Subset of the above, branching off to the zettel. ## See also * The [z-index](/z-index.html) of this site displays its folgezettel heterarchy. [^1]: Hence the German compound word "[folge]-[zettel]".
