Why is walking so good for the brain? Blame on the "spontaneous fluctuations"

[Bernardo de La Paz]

16. Great article, but very bad linkage of imagination and divergent thinking to "irrational"

It is a big mistake to assume, as the article starts out, that the positive states of "divergent thinking and imaginative mind-wandering" are "irrational".

First, the rational / irrational dimension of thinking is orthogonal to the imaginative wandering dimension. Orthogonal meaning that the dimensional axes cross and are not parallel. We use those processes for different purposes at different times. Presumably "divergent thinking" is akin to "imaginative mind-wandering", though neither are defined.

Second, "irrational" has a very negative sense all around it and linking other dimensions of thinking to something so negative is needlessly giving them a huge burden to get out from under.

But read the article. The concepts of fractal nature and fractal neural activity are important and lead to the idea that thinking itself is fractal. Good article.
