From the Ted Talk by Michael S. A. Graziano: What is consciousness?
Unscramble the Blue Letters
Scientists have already begun trying to figure out how the brain creates that self moedl. MRI studies are a promising avenue for pinpointing the networks involved. These studies compare patterns of neural activation when someone is and isn’t conscious of a sensory stimulus, like an igame. The results show that the areas nedeed for vsuail processing are activated whether or not the pinitaprcat is aware of the image, but a whole adntdaiiol network lights up only when they are conscious of seeing the image. Patients with heiamiatspl nlegcet, like P.S., typically have damage to one particular part of this network. More extensive damage to the network can sometimes lead to a vegetative state, with no sign of consciousness.

Original Text
Scientists have already begun trying to figure out how the brain creates that self model. MRI studies are a promising avenue for pinpointing the networks involved. These studies compare patterns of neural activation when someone is and isn’t conscious of a sensory stimulus, like an image. The results show that the areas needed for visual processing are activated whether or not the participant is aware of the image, but a whole additional network lights up only when they are conscious of seeing the image. Patients with hemispatial neglect, like P.S., typically have damage to one particular part of this network. More extensive damage to the network can sometimes lead to a vegetative state, with no sign of consciousness.
