book review: The Mind's Past

Michael Gazzaniga’s book "The Mind's Past" attempts to elucidate how the brain functions as a unified whole. He proposes a left-brain interpreter, which transforms the plethora of systems and networks active in the brain, into a single narrative. Gazzaniga emphasizes the importance of automatic, unconscious processes distributed throughout the brain that require meaning to be attributed by another cognitive model. The interpreter seeks patterns and understanding from these discrete systems, and makes sense of subconscious mechanisms comprising what we would consider as the self. Located in the same region as language functions, the interpreter may be viewed as an evolutionary adaptation to construct our conscious reality based on reflexive, automatic processes that are constantly occurring in the brain. Gazzaniga is the product of Nobel laureate Roger Sperry’s laboratory, and the two worked extensively with split brain patients to examine the lateralization of the two hemispheres in the brain. The idea that an interpreter generates conscious feelings and awareness was spawned from a number of cases where patients did not seemingly experience sensations, yet were able to communicate an unconscious understanding of the stimuli. This illustrates the trickiness of the brain, where the ability for information to be perceived by the senses does not depend on the conscious awareness. So why are we conscious beings at all? The interpreter theory paints a nice explanation for stuff that we have yet to understand, but its kinda like saying that God is responsible for creating the earth and people and that neat ark.
