Questions about some Columbus tubings

Perhaps someone can provide me with some clarifications about some specific Columbus tubing. I have seen some bikes recently with Brain tubing and with Neuron tubing.

It seems as though the Brain tubing might have changed a little over time. There is a Torelli Super Strada for sale on Craigslist with Brain tubing and the tubing is standard size. I thought Brain was oversized tubing. Is it true that early on it was a standard size tubing and nothing particularly special and then later on it evolved into an oversized tubing that was held in higher regard? Did standard size Brain tubing come out as Columbus was moving away from SLX?

With regard to the Neuron tubing, was that always an oversized tubing and what is the general consensus as to its performance, stiffness, durability, etc.?

And then there is whether there are elliptical features on these tubings. I am just a little confused at this point and trying to sort this all out.

Also should add that I am inquiring about older (early to mid 90's) versions of these tubings, not anything that might be recently produced.
Thanks for any info!

I know that Marin had some road bikes manufactured by Billato in Italy beginning in 1998 (I think). The Brain tubing in one model was shaped, at least the downtube. Not sure about chainstays, but it was a very stiff steel frame for it's day. I cannot recall if the ST & TT were oversize. The model below it used round Thron tubing and was much softer riding.

edit = found the 1999 Marin catalog and there were 2 models using Brain. The Top and Down tubes are Brain MegaTube on the San Marino & Vicenza models. One lists a Brain OS fork.

Nemo Megatube on the most expensive model; Thron MegaTube on the least expensive model.

Sorry, I can only be sure of this one data point; but I'm guessing the Brain tubing could have been drawn to either OS or standard size tubes.
Vintage, modern, e-road. It is a big cycling universe.

Correct. The OP cross-posted in several forums and I offered what I thought was a pretty thorough response in Road Cycling.
