Decentralize

While we all agree octopus is an intelligent creature, the structure of its central nervous system is remarkable.

I mean remarkably simple.

For those familiar with human anatomy, our brain has a good map of the whole body in terms of sensory and motor function. Cerebral cortex knows what's happening everywhere, and all complex movements - single synapse thinking by medical graduates excluded - are decided by supratentorial structures.

But octopus is different. It has no internal somatotopic map of its body, and most of the complex motor skills are not controlled by the central brain. In compensate, each arm of an octopus has an individual nerve cord, which has - in modern terms of business management - a high degree of autonomy in controlling the limb movement.

Alas, this design is, in itself, intelligent. To say the least, unlike dinosaurs, octopus does not decentralize its body control to a single place called asshole.

PS. For those who are not familiar with the neuroanatomy of dinosaur, please refer to http://ccszeto.blogspot.com/2009/10/stegosaurus.html
