Disputes between rival theories of consciousness have often centered on whether perceptual contents can be decoded from the prefrontal cortex (PFC). Failures to decode from the PFC are taken to challenge ‘cognitive’ theories of consciousness such as the global workspace theory and higher-order monitoring theories, and decoding successes have been taken to confirm these theories. However, PFC decoding shows both too much and too little. Too much because cognitive theories of consciousness do not need PFC rerepresentation of perceptual contents since pointers to perceptual representations suffice. Too little because there is evidence that PFC decoding of perceptual content reflects postperceptual cognitive representation, such as thoughts that have those perceptual contents rather than conscious percepts.

PFC 的解码揭示了关于意识的什么？


对立的意识理论之间的争论常常集中在感知内容是否可以从前额皮质（PFC）解码。前额皮质解码失败挑战了意识的“认知”理论，例如全局工作空间理论和高阶监控理论，而解码成功则证实了这些理论。然而，PFC 解码显示的内容既太多又太少。太多了，因为意识的认知理论不需要 PFC 对感知内容的重新表征，因为指向感知表征的指针就足够了。太少了，因为有证据表明 PFC 对感知内容的解码反映了感知后的认知表征，例如具有这些感知内容而不是有意识感知的思想。
