So what is Huther onto (see previous entry)?
For decades the presumption was that the neuronal pathways and synaptic connections established during the brain’s initial development were immutable. Today we know that the brain is capable throughout our lifetimes of adaptively modifying and reorganizing the connective pathways that it has laid down, and that the development and consolidation of these pathways depends in quite a major way on how we use our brain and what for.
So what does this mean in some larger sense. Well, it means the structure of any particular brain….and one can only study particular brains…may well not be the structure of any other brain with the consequence that locating an immutable DNA conditioned structure is difficult, if not down right impossible. Certainly down there somewhere is a structure determined by DNA but “overlaying” that structure are all the structures or networks that arise from the inter-relation of the organism with its environment.
A few years ago, no researcher in the field of brain science could have conceived the possibility that what we experience could be capable of changing the structure of the brain in any way. Today most scientists who study the brain are convinced that the experiences of our lives do become structurally anchored in the brain.
This notion that experiences themselves can “program” the brain or create structures provides some “scientific” proof for the process of socialization…that sociologists talk so much about. We learn, it might be said, from experience when those experiences create a new structure or reprogram the brain in some way.
Consequently, Huther argues that human beings did not develop big brains so that they might think or reason but so that they might become socialized. He writes: “Our brain is thus much more a social organ than it is a thinking organ.”
The brain of course is not equally open at all stages of development to being reprogrammed through experience (as the interaction of the organism with it environment). Rather, more like Freud than not, Huther suggests that the most profound and possibly unalterable experiential reprogramming occurs during the first year of life. Reprogramming or possibly first programming at this level is so profound, so obdurate that structures produce by it may appear DNA determined. They are not however and possibly because they are not Huther proposes as a kind of ideal brain one that is not boxed in by its early experiences but capable across the whole life cycle of learning (being reprogrammed by experience).
Very few and relatively rare individuals however achieve this brain ideal. Rather, to use Huther’s phrase, most of us develop brains that are in one way or another “one-sided” and relatively unopen to alteration. To address this problem he suggests scientists should expend less energy on asking how the brain is structure and more on how the brain is used, for how we use the brain is what determines whether “…the potentialities built into it can really be fully actualized.”
