In our discussion of Christopher Reeves I understood conceptually why and how his toe retracts when it gets pinched, but it made me wonder how that reaction is programmed and/or saved into the motor and sensory neurons in that part of the nervous system. It seems very connected to our discussion of which actions become separated from the I-function, such as muscle memory. It makes me think that there are different types of memory. Maybe they are dependent on which types of neurons are engaged in the action, for example reflexes like responding to pain when your toe is pinched, or muscle memory like walking or riding a bike use motor neurons that are not dependent on the I-function to work. I was also interested in somebody else's question about dreams, and I would make it a question of the distinction between thought and action.
