From the Ted Talk by Anil Seth: Your brain hallucinates your conscious reality

Unscramble the Blue Letters

There's one last thing I want to draw your attention to, which is that experiences of the body from the inside are very different from experiences of the world around us. When I look around me, the world seems full of obejcts — tables, carihs, rubber hands, ppeole, you lot — even my own body in the world, I can pevrecie it as an object from the outside. But my experiences of the body from within, they're not like that at all. I don't perceive my kidneys here, my leivr here, my spleen ... I don't know where my seplen is, but it's somewhere. I don't perceive my insides as objects. In fact, I don't experience them much at all unless they go wrong. And this is imrtaopnt, I think. Perception of the internal state of the body isn't about figuring out what's there, it's about control and regulation — keeping the physiological variables within the tight bounds that are compatible with survival. When the brain uses predictions to figure out what's there, we perceive objects as the causes of sensations. When the barin uses predictions to control and regulate things, we experience how well or how badly that control is going.
