The spaghetti box model of the nervous system: stimlus, response
But if brain=behavior:
- Harvard Law of Animal Behavior
- Different in different people, changes with time in same person
Being less wrong: boxes within boxes: input, output, autonomy
Looking at the real thing ("its boxes all the way down" - input neurons, output neurons, interneurons)
- Subdividing the vertebrate nervous system
- Central vs peripheral
- Telencephalon, diencephalon, mesencephalon, rhombencephalon, spinal cord
- Boxes within those boxes (eg thalamus, hypothalamus)
- Accounting embryologically for basic vertebrate central nervous system plan
- long neural tube with rostral swelling, clearest in frog, folded/covered over by neocortex in mammals
- Variations in mammalian, vertebrate brains
- "Sort of the same, sort of different"
- Neocortex prominent in mammals, absent in frogs, fish
Brains "similar but different"
Boxes semi-autonomous
- Christopher Reeves
- The self and I-function
