A leech (Hirudinea) has 32 brains throughout its segmented body. An Octopus (Octopoda) has 9 brains, one for its head and 8 for its arms (legs?).
How do these animals process tasks using multiple brains? It would suck if 3 out of your 8 arms wanted to go find a place to hide while your brain and other 5 arms are actively hunting.

Humans have an enteric (intestines) nervous system which acts independently from the brain while simaltaneously communicating with the brain. Similarly, the spinal cord controls reflexes before the signals even reach the brain.
In regards to the octopus and leach comparisons, another commenter perfectly summed up how they would use there *polybrain* bodies
