"To understand how neurons and nervous systems first evolved, we need
an account of the origins of neural elongations: why did neural
elongations (axons and dendrites) first originate, such that they
could become the central component of both neurons and nervous
systems? Two contrasting conceptual accounts provide different answers
to this question. Braitenberg's vehicles provide the iconic
illustration of the dominant input-output (IO) view. Here, the basic
role of neural elongations is to connect sensors to effectors, both
situated at different positions within the body. For this function,
neural elongations are thought of as comparatively long and specific
connections, which require an articulated body involving substantial
developmental processes to build. Internal coordination (IC) models
stress a different function for early nervous systems. Here, the
coordination of activity across extended parts of a multicellular body
is held central, in particular, for the contractions of (muscle)
tissue. An IC perspective allows the hypothesis that the earliest
proto-neural elongations could have been functional even when they
were initially simple, short and random connections, as long as they
enhanced the patterning of contractile activity across a multicellular
surface. The present computational study provides a proof of concept
that such short and random neural elongations can play this
role. ..."
