Changing stimulus and response to input and output and restructuring the "box" has made it easier for me to accept that the brain and behavior are one. Breaking the large box into segments, depicts a more accurate view of the brains autonomous functions and interrelations. Due to the fact that there are infinite combinations of output from the brain, the partition among boxes allows us to visualize the brain as an autonomous structure which can be broken down into still smaller autonomous structures. The first vague box with it's corresponding arrows was disconcertingly ambiguous. The updated box is more accurate and clear.
And raises new questions? Can you be more specific about why you like the segements, what autonomy means to you, is good for? PG
