More than that, our brains have multiple input and output devices that simultaneously interact with the brain. Proprioception, sight, hearing, touch inputs. Movement, cognition, hormone regulation as outputs. There's a biological basis for why walking stimulates thought, the same networks are involved. It's not the same thing as training the same NxM deep neural network on multiple modalities and then sending one signal or the other into the input end.
