plexusy

Plexusy is a term used in discussions of network theory to describe a densely interconnected system in which many components connect to many others, creating a web-like topology. It can refer to real-world networks, such as neural plexuses in biology or engineered mesh networks, as well as abstract models used in systems theory and data science. The term is a neologism formed from plexus (a braided or interwoven structure) and busy, intended to capture persistent interactivity and redundancy.

The term was first introduced in scholarly writings in the late 2010s by researchers exploring emergent properties of highly interconnected networks. Since then, plexusy has been used to discuss how local interactions produce global behavior, how resilience emerges from redundancy, and how scalability challenges arise in dense topologies.

Key characteristics of plexusy systems include high node degree, multiple alternate paths between points, redundancy to tolerate failures, distributed control, and potential for complex dynamics such as feedback loops and cascading effects. In biology, anatomical plexuses like the cardiac or solar plexus are commonly described using the same intuition, though they are not formalized under the term.

Applications span neuroscience, where plexus-like networks organize signals; computer networks, particularly mesh and overlay networks; and urban or logistical planning, where densely interconnected routes or facilities resemble plexusy structures. Critics note that the term can obscure precise mechanisms unless accompanied by specific metrics or formal definitions.
