Much research on the neural correlates of consciousness (NCC) has focused on two evoked potentials, the P3b and the visual or auditory awareness negativity (VAN, AAN). Surveying a broad range of recent experimental evidence, we find that repeated failures to observe the P3b during conscious perception eliminate it as a putative NCC. Neither the VAN nor the AAN have been dissociated from consciousness; furthermore, a similar neural signal correlates with tactile consciousness. These awareness negativities can be maximal contralateral to the evoking stimulus, are likely generated in underlying sensory cortices, and point to the existence of a generalized perceptual awareness negativity (PAN) reflecting the onset of sensory consciousness.

许多关于意识神经关联 (NCC) 的研究都集中在两个诱发电位上，即 P3b 和视觉或听觉意识负性 (VAN、AAN)。调查最近广泛的实验证据，我们发现在有意识的感知过程中反复未能观察到 P3b 将其排除为假定的 NCC。VAN 和 AAN 都没有与意识分离；此外，类似的神经信号与触觉意识相关。这些负面意识可能是诱发刺激的最大对侧，很可能在潜在的感觉皮层中产生，并表明存在反映感觉意识发作的广义知觉负面（PAN）。
