ance of an “internuncial neuron,” a cell sandwiched between the sensory
and the motor unit (Fig. 9). It is, in essence, a sensory cell, but specialized
so as to respond only to a universal “agent,” namely, the electrical activity
of the afferent axons terminating in its vicinity. Since its present activity
may affect its subsequent responsivity, it introduces the element of com-
putation in the animal kingdom and gives these organisms the astounding
latitude of nontrivial behaviors. Having once developed the genetic code
for assembling an internuncial neuron, to add the genetic command repeat
is a small burden indeed. Hence, I believe, it is now easy to comprehend
the rapid proliferation of these neurons along additional vertical layers with
growing horizontal connections to form those complex interconnected
structures we call “brains.”
