The current debate about the rights of the self-employed raises the question of how much control we have over our work. Is an Uber driver really their own boss if they are controlled by a corporation? And how much does it affect work performance?

A great deal, from a neuroscientific perspective. There is a crucial difference between movements you control and movements you make when you slavishly follow external direction. The cerebellum predicts what these movements will be depending on how planned they are. If, for example, you move your arm to follow a dot on the screen, rather than tracing your own path, the brain activations will be different.
