RE: [xmca] Plasticity and Physiotherapy



I think Sebastion Sueng (sp?) has a really interesting take on this.  We can see at a macro level how behavior impact brain functioning, but the information we get is very gross and interpretable in a number of directions.  But at the micro-level, where actually synapses actually come into contact with each other at any given time, if we are honest we simply don't have the instrumentation to observe this - unless we cut open the brain.  So it all has to be conjecture.  It can be very good conjecture, but conjecture all the same.
 
What is so interesting about this is how it is the opposite of the study of human behavior and speaks to Martin's question about empirical evidence for cultural impact on behavior.  We are able to get really good information at the micro-level, but everything becomes confused and muddled when we try to take it macro.

Our 10 year old girls were on the same team and while they played we shared some interesting stories and observations about how they learned and practiced skills, in schools and in sports. He seemed genuinely interested in my perspective and experience as a parent and a teacher, sharing his own observations as an involved and active parent. One day, I asked this father what his profession was and he told me he was a neurologist. I then asked him some questions about the possibility of different functional systems in trying to understand some unusual patterns in student reading and writing. I wish I could remember what he said directly, but it amounted to a cursory opinion that neurology had nothing to do with learning and that I, as a teacher working with students, couldn't possibly observe anything that had to do with the functioning of the brain at the level he worked at. That he seemed so genuinely interested in the inquiry about the development of his daughter from a personal stance, but did not connect what he knew professionally to the same inquiry came as a shock and a mystery. I had the same question you had, Andy.

> That gives us the Kuhnian story (with an ethical twist)  of why neuroscience required a fixed machine for its discipline and how the paradigm shift occurred, but what is missing is how it was that outside of the discipline others knew that the brain changed. This is what intrigues me. How a discipline can maintain a fiction about its own object of study whilst outside the discipline people know it is a fiction. I am presuming it has a lot to do with the sociology of science and the status of the various sciences. But I will see if I can find something.
