Neuro-imaging techniques reveal how we create a sense of self, a narrative.

November 27, 2010

Neuro-imaging techniques are revealing some of the mechanics behind how left brain and right brain work together to enable us to develop a sense of self.

State-of-the-art neuro-imaging and cognitive neuropsychology both uphold the idea that we create our "selves" through narrative. Based on a half-century’s research on "split-brain" patients, neuroscientist Michael Gazzaniga argues that the human brain’s left hemisphere is specialised for intelligent behaviour and hypothesis formation. It also possesses the unique capacity to interpret – that is, narrate – behaviours and emotional states initiated by either hemisphere. Not surprisingly, the left hemisphere is also the language hemisphere, with specialised cortical regions for producing, interpreting and understanding speech. It is also the hemisphere that produces narratives.
