Split-brain surgeries and hemispheric dominance January 21, 2011

This BBC news article is an interesting reference to epilepsy treatment via corpus callosum surgeries. Made famous by Roger Sperry and his colleagues, corpus callosum surgeries (the tissue that connects both left and right hemispheres of the brain) cured epilepsy, but left patients effectively with 2 brains as mentioned in the article. This is, of course, seen more extremely in the case of the lady in the article.

Whole Brain Thinking emerged from these surgeries as an organising metaphor for thinking preference instruments like the Herrmann Brain Dominance Instrument (HBDI) and Emergenetics.  But for epileptic patients, Whole Brain Thinking is definitely more than just a metaphor, but a state of desired existence.
