一位名叫P.S.的病人中风伤及右脑，使她对左侧失去意识。如果有人朝她左侧丢球，她可能会闪躲，但她却察觉不到那个球也不知自己为何闪躲。意识到底从何而来？Michael Graziano探索了这个几世纪来困扰着科学家和哲学家们的问题。

Consciousness may arise from the brain’s own imperfect model of itself. After a stroke, patient P.S. could avoid dangers on her left side without knowing why, showing a stark divide between sensory processing and conscious awareness. The brain builds constantly updated, simplified models of the world, the body, and even its own attention. Experiments suggest a specific neural network transforms raw perception into conscious experience, but much about its inner workings remains mysterious.
