I try to keep up with reading about the neuroscience of the brain. This is an evolving topic especially over the last 50 years and therefore read many a book on this subject.

An interesting article and mathematical research publication claim that the progression of activity through the brain resembles a multi-dimensional sandcastle that materializes out of the sand and then disintegrates. And that <quote> "We found a world that we had never imagined. There are tens of millions of these objects even in a small speck of the brain, up through seven dimensions. In some networks, we even found structures with up to eleven dimensions." <end quote>

An 11D brain makes it more complex than previously imagined. And this is perhaps a starting point for further understanding the complexities of the brain and its function, and I find this progress fascinating.
