The Embodied Brain

Though the title of this very blog may lead one to suppose that the processes of human thought, feeling and behaviour are “All in Our Heimgresad” this, in fact, couldn’t be further from the case. The human brain is directly and intimately connected with the body of the human organism. We think what we think, feel what we feel, we are who we are and do what we do both because our brains are wired up in a particular way and because our bodies are configured and composed in a unique manner.

The recent discovery of direct, previously undetected connections between the human brain and the immune system is just one example of the reciprocal relationship between the mind and the body, suggesting the significance of the concept of the “embodied brain”…an idea that will be explored in much more depth in a series of upcoming posts…

In a stunning discovery that overturns decades of textbook teaching, researchers at the University of Virginia School of Medicine have determined that the brain is directly connected to the immune system by vessels previously thought not to exist.

That such vessels could have escaped detection when the lymphatic system has been so thoroughly mapped throughout the body is surprising on its own, but the true significance of the discovery lies in the effects it could have on the study and treatment of neurological diseases ranging from autism to Alzheimer’s disease to multiple sclerosis.

“Instead of asking, ‘How do we study the immune response of the brain?,’ ‘Why do multiple sclerosis patients have the immune attacks?,’ now we can approach this mechanistically – because the brain is like every other tissue connected to the peripheral immune system through meningeal lymphatic vessels,” said Jonathan Kipnis, a professor…

In Our Head Facts- Brain Dominance

In an age where a 140 character message can spread around the world like the wildest of wildfires or a pizza-slice can transform into a bikini model with the artistic flare of a photo-shop engineer, we should be adept at closing our ears to hearsay and tattle and all sorts of false truths. Every now and then however the intuitive appeal of certain ideas tend to seep through even the most stringent of BS filters, making their way into a common garden of popular misconceptions.

One such idea is the weed of a notion that one side of our brain is more functionally dominant than the other resulting in individual differences in traits such as creativity, analytic ability or orderliness.

With Facebook statuses sharing results from BuzzFeed brain-dominance tests, professional write-ups detailing the personality traits of those who use one hemisphere of their brain more so than the other, even guidance counsellors basing career recommendations on tests of brain-sidedness, this myth just wont die.

To slice the ever-growing misconception at its stem, it is simply not true that one side of the brain does reason and analytical thinking and the other emotion and creativity. Simply not true. It is not true that the left-hemisphere is 100% responsible for language, or that the right-hemisphere is entirely in charge of creative thought.

Not. True.
