How does the inner voice work?

In order to understand how the inner voice works, you need to understand how human thought translates into action. “Whenever we do any action, our brain makes a prediction of the sensory consequences of that action,” says Loevenbruck. Say you want to fetch a glass of water. “Your brain sends the appropriate motor signals to your hand, but it also generates a sensory prediction of the command,” she says. “Before you’ve even picked up the glass, your brain has made a prediction of what the motor command will do, which means you can correct for mistakes before you make an error.
