consciousness disorders  

Definition

  • As far as we know, a living being without a brain cannot have conscious experiences. But are certain parts of the brain more critical for conscious awareness than others? More specifically, how might disorders of perceptual consciousness after damage to the human brain inform the scientific world about relationships between neural systems and conscious perceptual awareness? In many cases, the loss of awareness is accompanied by indications that “invisible” information is nevertheless still being processed by the visual cortex.
