The physiological concept of the "final common pathway"

The concept of the final common pathway emerged as an answer to a scientific question: are the peripheral muscles and glands controlled by multiple nervous inputs from independent controlling centers, or do all the various inputs act through one 'final common pathway'? It turns out that indeed final common pathways do exist in the form of specific motor neural pathways shared by nerve impulses from many central sources on their way to a muscle or gland in the periphery. It does makes sense to have a network sharing information instead of everything being hardwired.

The tried and true concept of final common pathway applies to consciousness too, as all its inputs feed into the final common pathway of our experience.
