"We are our narratives" has become a popular slogan. "We" refers to our selves, in the full-blooded person-constituting sense. "Narratives" refers to the stories we tell about our selves and our exploits in settings as trivial as cocktail parties and as serious as intimate discussions with loved ones. We express some in speech. Others we tell silently to ourselves, in that constant little inner voice. The full collection of one's internal and external narratives generates the self we are intimately acquainted with. Our narrative selves continually unfold.

[Neuroscientist Michael] Gazzaniga also thinks that this left-hemisphere "interpreter" creates the unified feeling of an autobiographical, personal, unique self. "The interpreter sustains a running narrative of our actions, emotions, thoughts, and dreams. The interpreter is the glue that keeps our story unified, and creates our sense of being a coherent, rational agent. To our bag of individual instincts it brings theories about our lives. These narratives of our past behaviour seep into our awareness and give us an autobiography,"

One compelling study used PET imaging to watch what is going on in the brain during inner speech. As expected, this showed activity in the classic speech production area known as Broca's area. But also active was Wernicke's area, the brain region for language comprehension, suggesting that not only do the brain's speech areas produce silent inner speech, but that our inner voice is understood and interpreted by the comprehension areas. The result of all this activity, I suggested, is the narrative self.
