sidesyn
Sidesyn is a term used in several disciplines to denote coordination, synchronization, or synthesis between the two sides of a system. The word is a blend of side and synthesis or synchronization and has no single, universal definition. In scientific literature, it is not a standard term; it is sometimes used informally to describe interhemispheric coordination between the brain's left and right hemispheres during tasks that require bilateral processing, such as coordinated hand movements or spatial judgment. In this sense, sidesyn can be seen as a layperson’s way of referring to interhemispheric communication, which relies on neural pathways such as the corpus callosum.
In technology and design contexts, sidesyn is sometimes used to describe symmetrical or mirrored design principles
Etymology: a portmanteau of side and synthesis or synchronization. Because it is not a formal technical term,
