Not for neuro. 'sOkay. <g>

Clockwork's gear is not a processor.
Just a conduit.
Even axon 'pipe' is more than conduit.
Single neuron has not only bigger instruction
set than the gizmo you're using to read this,
but has semi-autonomy; it maintains itself alive,
and 'relates' (broad use of word) to other cells.
It is more complex than most other cell
types (debatable whether neuroendocrine
cell is more or less-- depending on
level-of-consideration, and neuron type).
Remember all those modulating processes?
(might be time for some textbook
Also, single neuron, unlike clock gear,
is nearly never *essential*--
Several more reasons why bad analogy;
previous over-suffice WRT granularity
of current discussion.
