No one in this thread, or in the article, has claimed that gray matter is randomly distributed.
Regarding your comment about how incompetent I am, and how extremely strange this MRI analysis is:
Measuring cortical thickness by MRI is a standard technique in neuroanatomy since 15 years ago. And really, a quick search of the literature would have shown you this. But I suppose that's too much to ask.

I simply cannot imagine what you think is going on in order for them to be looking at "clumping" of gray matter as a proxy for density of the tissue via MRI and calling this "thickness".

I thought perhaps you knew some technical detail about their analysis pipeline, but you still haven't mentioned anything technical... so I just don't have any idea what you are thinking.

Sure, here is the first article I found regarding "cortical thickness":
Like I already told you, in order to fix your ignorance of how researchers use jargon, you can go through the literature. I'm sorry, but I'm not here to teach you these things, and it's not really my concern whether you're informed or not. I can recommend using Google Scholar as a starting point if you'd actually (surprisingly) be interested in educating yourself.
