When I start thinking about behavior the number of questions that i don't know how to approach answering is simply overwhelming. Even though I do beleive that many of these questions will be answered in the future (I believe in science), it is still incredible how much work has been involved> in research of the Nervous System as well as behavior. When I think about the fact that we are discussing the chemical constitution of our thoughts, movements,beleifs I can't help but think that five hundred years ago even the > thought of such explanation were unconceivable. I just think that this is incredible.

All the suggestions made in class in order to explain the connection between Nervous system and behavior are perfectly reasonable and seem to make perfect sense in realtion to the experiments proposed. Yet, it is incredible to think about how much is yet to be explained!

The behavior can definetely is better explained by the recent propositions made in class, since we can use our model of motor symphony to account for more general occurences and not just for tiny (yet, incredibly important) events such as action potentials. For example the fact that we can now somehow rationalize memory and learning (as in the example of remembering how to type). I wonder if this model can also explain forgetting? In other words, do motor symphonies get erased? I know that Freud would not agree with even the formulation of the question, since, as far as I know, he did not beleive in forgetting, just repressing. Yet,it seems interesting that even with the example of typing, if we have not typed for a while we are not as quick as we used to be. Does it mean that the motor symphony has to be rewritten again?

Interesting issue: forgetting versus repressing. But certainly some patterns of change in the nervous system can disappear with time (although others remain remarkably stable, like knowing how to ride a bike even if you haven't for a long time). I don't know of anyone looking at "erasing" of motor symphonies and it might well be interesting to do so. Yep, lots yet to be explained (which, incidentally, is a good sign for the idea that brain=behavior: "good" ideas can usually be recognized by how many new and approachable questions they raise). PG
