Generally not. Which is why the nervous system of cephalopods seems so alien — their processing is performed in a more distributed fashion. Sometimes the brain and spinal column are considered together in our case, as some of our survival reactions are governed by neurons in our spine, but that does not really match how cephalopods distribute their processing (something that is presumably necessary, or at least helpful/efficient, for controlling the flexibility of their limbs).
