Abstract

Neurons make networks of intercellular connections. Many other cells also send out long cellular extensions and “touch” other cells far away. The extensions are intriguing, but what do they do? Possible rationales for this cell behavior include: (1) forming precise binary connections with the possibility of forming more complex networks, and (2) coupling of signaling with physical force.
