"I want to help people to notice things consciously that they might not otherwise see, and remain open to the possibilities. Noticing is one thing, and building on it or connecting it to other things is the next step. Some of this can be learned and we now have a discipline for it." He is already looking at other obstacles and plans to publish a series of innovation-enhancing techniques to address as many as two dozen distinct creativity blocks caused by the normal function of our perceptual and cognitive systems.

The one technique described in the article has striking similarities to Jainist/Buddhist mental exercises for "releasing/letting go of karma".

On reconstructing thoughts with fMRI scans.
Quote
The idea of seeing life through someone else’s eyes has long been a theme in our fiction and our fascination. The opportunity to access the inner world of another human was accounted famously in the cult classic, Being John Malcovich. Variations on the theme have been showcased in a lengthy roster of Hollywood productions, such as, Freaky Friday, The Change Up, and an unfortunate number of Look Who’s Talking productions, to name a few.
Currently a few weeks old, still, it might be time to practice thinking with the other side of my brain, again...

http://www.nature.com/news/human-brain-shaped-by-duplicate-genes-1.10584

Apparently, a large part of the difference between human brains and chimpanzee brains is due to two successive duplication errors of a single gene.  Also, they put the human form of this gene in mice, so it turns out that the "Pinky and the Brain" cartoon was prophecy.  Narf!

Quote
Surprisingly, the SRGAP2C protein blocks the action of the ancestral protein, Polleux’s team discovered, effectively rendering humans as 'knockouts' for the ancestral SRGAP2 gene. The team then expressed the human form of SRGAP2C in the neurons of developing mice. The change didn’t cause the mice brains to enlarge, but their neurons produced denser arrays of brain cell structures, called dendritic spines, that forge connections with neighbouring neurons.

“If you’re increasing the total number of connections, you’re probably increasing the ability of this network to handle information,” Polleux says. "It’s like increasing the number of processors in a computer."

In mice, the gene also increased the migration speed of neurons across the developing brain. Polleux's team speculates that this trait could also have helped neurons to travel long distances in the enlarged brains of human ancestors.

I am a little concerned about the creation of genius mice.

Oh. And male mice. Male mice do not like other male mice and will try to kill each other.

16 Year old kid solves 300 year old physics riddle

The Brain May Disassemble Itself in Sleep

It's bumming me out that I can't get that first link to load...maybe later today.

The second one is fascinating, and I also wonder if there's any connection with the fact that I often wake up understanding math problems that I was struggling with when I went to bed.

No, that's just the Math Fairy.  You DID leave a small animal under the pillow, I hope.
