The irony..
Orch Or is is not studied by or supported by hundreds of scientists. Less than 5 if one is lucky or being generous.
Secondly, studying microtubules as scientists are studying it, does not validate Orch Or, nor does it have anything to do with it.
Thirdly, only a couple of scientists are claiming that it is where consciousness resides, and have failed to support their claims with any valid science and they have instead catered their claims to fit studies, and they have refused to address responses that disprove their claims.
Personally, I think Hameroff and Penrose are quacks.
While your accusation of "premature exaggeration" is ironic in and of itself, given the ridiculous manner you have conducted yourself in this discussion and the manner in which you have tried to spread microtubules across the site at every given opportunity, the biggest irony is that you have probably single-handedly turned most people on this site off studies conducted regarding consciousness and even worse, microtubules when it comes to things like cancer (treatment).. Reason for that is because people will now hesitate to even discuss it or bring it up.
Here is what you said:
It's not.
Not in the way that you are describing it.
No evidence to suggest that it is.
Then you should be looking at neurofilaments as they are more numerous in axons than microtubules.
And?
How about you let us adjust our monitors as we see fit, and you adjust yours as you see fit.
Really, the constant and random huge bold text is kind of annoying and obnoxious. It's not adding anything to your post, aside from irritation that is.
I can find a quote that summarises it in a few paragraphs when it comes to their roles in neurons.
Microtubules are 20 to 25 nm diameter tubular structures that run in loose bundles around the nucleus and funnel into the base of the axonal and dendritic processes where they form parallel arrays distributed longitudinally. They are made up of dimers of α and β tubulin subunits and contain associated proteins known as microtubule associated proteins (MAPS). The MAPS regulate the polymerization of tubulin subunits to form the microtubules. The dimers of α and β tubulin subunits polymerize to form proto-filaments arranged in an a helix such that 13 dimer subunits make up each full turn of the a helix. In addition, microtubules are not continuous, and each microtubule is composed of numerous 100 nm units. Microtubules are involved in axoplasmic transport (see below).
Their role in dendrites:
The membrane of the neuron functions as a receptive surface over its entire extent; however, specific inputs (termed afferents) from other cells are received primarily on the surface of the cell body and on the surface of the specialized processes known as dendrites. The dendritic processes may branch extensively and are often covered with projections known as dendriticspines. Spines provide a tremendous increase in the surface area available for synaptic contacts. The dendritic processes and spines of neurons are essentially expansions of cytoplasm containing most of the organelles found in the cell body. Dendrites contain numerous orderly arrays of microtubules and fewer neurofilaments (see below). The microtubule associated proteins (MAPs) in the dendrite have a higher molecular weight than those found in the axon. An example is MAP2. In addition, microtubules in dendrites have their positive ends toward the cell soma. Mitochondria are often arranged longitudinally. Rough endoplasmic reticulum and ribosomes are present in large but not small dendrites. The shape and extent of the "dendritic tree" of an individual neuron is indicative of the quantity and variety of information received and processed by that neuron. The dendritic spines often contain microfilaments which is the cytoskeletalelement responsible for changes in spine shape observed in some examples of synaptic plasticity.
Soma:
The interior of the soma consists of cytoplasm, a gel within a microtrabecular lattice formed by the microtubules and associated proteins that make up the cytoskeleton.
Axon:
The other type of process in the idealized neuron is the axon. Each neuron has only one axon and it is usually straighter and smoother than the dendritic profiles. Axons also contain bundles of microtubules and neurofilaments and scattered mitochondria. The most MAPs in an axon have a lower molecular weight than those in the dendrite. A predominant MAP in axons is tau. Microfilaments within the axon are usually associated with an area adjacent to the plasmalemma and often are the most dense at the nodes of Ranvier. Beyond the initial segments, the axoplasm lacks rough endoplasmic reticulum and free ribosomes. The branches of axons are known as axon collaterales. The axon itself is often surrounded by a membranous material, called the myelin sheath, formed by glia cells. The myelin sheath acts to insulate the plasmalemma of the axon in a way that necessitates the more rapid spread of the depolarization of the plasmalemma and increases the speed of conduction of the nerve impulse (see Chapter 3).
Do you view a prohibition on lying and exaggeration to be a restriction?
Because thus far, you have made wild claims that are completely unsupported and unfounded. Do you think the demand that you not do that is a restriction?
You aren't extolling the virtues of microtubules. You are acting like a religious zealot.
For example:
Still unproven.
Nothing you have posted supports your own claims..
