Whether thalamocortical interactions play a decisive role in conscious perception remains an open question. We presented rapid red/green color flickering stimuli, which induced the mental perception of either an illusory orange color or non-fused red and green colors. Using magnetoencephalography, we observed 6-Hz thalamic activity associated with thalamocortical inhibitory coupling only during the conscious perception of the illusory orange color. This sustained thalamic disinhibition was temporally coupled with higher visual cortical activation during the conscious perception of the orange color, providing neurophysiological evidence of the role of thalamocortical synchronization in conscious awareness of mental representation. Bayesian model comparison consistently supported the thalamocortical model in conscious perception. Taken together, experimental and theoretical evidence established the thalamocortical inhibitory network as a gateway to conscious mental representations.

丘脑皮质抑制动力学支持有意识的感知

丘脑皮质相互作用是否在意识感知中起决定性作用仍然是一个悬而未决的问题。我们呈现了快速的红色/绿色闪烁刺激，这会引起幻觉橙色或非融合红色和绿色的心理感知。使用脑磁图，我们观察到与丘脑皮质抑制耦合相关的 6 Hz 丘脑活动仅在有意识地感知幻觉橙色期间。在有意识地感知橙色期间，这种持续的丘脑去抑制在时间上与更高的视觉皮层激活相结合，提供了丘脑皮层同步在有意识地意识到心理表征中的作用的神经生理学证据。贝叶斯模型比较始终支持有意识感知中的丘脑皮层模型。综合起来，
