On brain hemispheres:
The neuroscience of introspection seems to be that it is conducted by the right hemisphere of the brain. "The right hemisphere thinks in pictures and learns kinesthetically." (Jill Bolte Taylor)
“The first appreciation of anything comes to us via the right hemisphere, and the ultimate understanding of it in context does so also. Some very subtle research by David McNeill, amongst others, confirms that thought originates in the right hemisphere, is processed for expression in speech by the left hemisphere, and the meaning integrated again by the right (which alone understands the overall meaning of a complex utterance, taking everything into account). More generally I would see the left hemisphere as having an intermediate role: it ‘unpacks’ what the right hemisphere knows, but then must hand it back to the right hemisphere for integration into the body of our knowledge and experience." (McGilchrist, The Master and His Emissary.)
Notwithstanding Jill Bolte Taylor's entertaining talk in TED about her personal experience of her stroke, apparently, the latest finding is, it is not quite so simply so.
From http://www.livescience.com/39373-left-brain-right-brain-myth.html
There is a misconception that everything to do with being analytical is confined to one side of the brain, and everything to do with being creative is confined to the opposite side, Anderson said. In fact, it is the connections among all brain regions that enable humans to engage in both creativity and analytical thinking.
"It is not the case that the left hemisphere is associated with logic or reasoning more than the right," Anderson told LiveScience. "Also, creativity is no more processed in the right hemisphere than the left."
And from http://www.theguardian.com/commentisfree/2013/nov/16/left-right-brain-distinction-myth
From self-help and business success books to job applications and smartphone apps, the theory that the different halves of the human brain govern different skills and personality traits is a popular one. No doubt at some point in your life you've been schooled on "left-brained" and "right-brained" thinking – that people who use the right side of their brains most are more creative, spontaneous and subjective, while those who tap the left side more are more logical, detail-oriented and analytical.
Too bad it's not true.
In reality:
What research has yet to refute is the fact that the brain is remarkably malleable, even into late adulthood. It has an amazing ability to reorganize itself by forming new connections between brain cells, allowing us to continually learn new things and modify our behavior. Let's not underestimate our potential by allowing a simplistic myth to obscure the complexity of how our brains really work.
Bold added by me.
Also, from http://en.wikipedia.org/wiki/Lateralization_of_brain_function
Broad generalizations are often made in popular psychology about one side or the other having characteristic labels, such as "logical" for the left side or "creative" for the right. These labels are not supported by studies on lateralization, as lateralization does not add specialized usage from either hemisphere. Both hemispheres contribute to both kinds of processes. and experimental evidence provides little support for correlating the structural differences between the sides with such broadly-defined functional differences.
So, from a holistic perspective, both hemispheres of the brain are necessary for creativity and logical thinking.
Q.E.D.? :cheese:
