Characters of Our Own Creation

 From Big Think:

Consider three strands of evidence. First, the neuroscience. The linguistic explanations we create of our own behavior are generated by the language centers in our left cerebral cortex. In people whose brains have been surgically split in two, by severing the corpus collosum that links the left and right cortex, this means that language-generating machinery in the left cortex is necessarily completely oblivious to the machinations of the right cortex. As it happens, the right cortex sees the left half of the visual field and controls the left hand. So, when people with split brains are asked verbally to explain the actions of their left hand, you might expect them to be utterly mystified. But not at all! They are all too ready to confabulate a credible-sounding (though entirely baseless) explanation. (Read more.)
