Threads

"if [...] we cast a glance at the minute structure of the nervous system as recent discoveries have revealed it to us, we see everywhere conducting lines, nowhere any centres. Threads placed end to end, of which the extremities probably touch when the current passes [...].

But these threads which receive disturbances or stimulation from the external world and return them to it in the form of appropriate reactions, these threads so beautifully stretched from the periphery to the periphery, are just what ensure by the solidity of their connexions and the precision of their interweaving the sensorimotor equilibrium of the body, that is to say its adaptation to the present circumstances."
