I'm reminded of the 'hybrot' experiments where rat brain cells in a nutrient solution are allowed to wire up their own neural network on top of electrodes that send and receive data wirelessly from a robot body [https://www.technologyreview.com/s/401756/rat-brained-robot/ https://www.technologyreview.com/s/401756/rat-brained-robot/] The question of doing something similar with a strata running a human brain doesn't seem impossible, just extremely technologically daunting when one considers the sheer number of connections into and out of the physical brain.
