Cerebral Palsy maybe/maybe not

Now it gets really interesting. Go take a vitamin. You’ll need it. We must grapple with information theory & control. With this we need to consider that there are two functional ‘do it’ pathways, pyramidal and extra-pyramidal. The pyramidal pathway is the one you thought you already knew. The brain to muscle informational path (actually in cats, it isn’t). In most mammals and especially humans it is the telegraph line, hither to thither, with two transmission relays en route. So like pony express usually three horses to get the mail from here to there.

BRAIN nerve=======> New nerve=====> Last nerve===> muscle.

But is this 100% true? It is my theory, more a question, [based on behavior and on the edge uncertainties of histology sections wherein not all nerve fibers stain, but most do – just loose packing?] are there less repeated bits included? BRAIN nerve=======> New nerve=====> Last nerve===> muscle. BRAIN nerve=====================> Last nerve===> muscle. BRAIN nerve=======> New nerve=====> Last nerve===> muscle. BRAIN nerve=================================> muscle. BRAIN nerve=======> New nerve=====> Last nerve===> muscle.

This might not make neat-freaks happy, but it is good engineering in that a few faster arrivals let the target ease into its chore, not BANG! We do know that the extra-pyramidal

signals which are ALSO sent are sent a wee bit ahead. They adjust the receptors. If the result does not match the expectation, the spindles send ‘correction’ signals directly (to spinal cord built-in patterns- to muscle) so as to correct the difference..
