It has been proposed that both conscious and unconscious perception are associated with a feedforward sweep of oscillatory activity in the gamma band (>40 Hz), while conscious perception also requires recurrent feedback via beta band ([Form...
Replicating the unconscious working memory effect: a multisite Registered Report [0.03%]

Although in recent years some studies have found evidence suggesting that working memory (WM) may operate on unconscious perceptual contents, decisive demonstrations of the existence of unconscious WM are lacking. In the present Registered ...

Visual imagery and external perception rely on similar representations. However, whether the same processes underpin the subjective appraisal of both percepts and mental images is not yet known. One well-known effect in perceptual detection...
The possibilities of conscious experience in light of the dual origin hypothesis of the neocortex [0.03%]
双源假说视角下的新皮层意识体验的可能性研究

According to contemporary psycho- and physiological perspectives, the brain supports our experience of the world by constantly anticipating what may happen next. In this context, limbic mesocortical areas have been proposed to play a key do...
Now is the time: operationalizing generative neurophenomenology through interpersonal methods [0.03%]

Lived experience is shaped by intersubjective, social, cultural, and historical dimensions. For the past 30 years, neurophenomenology has adopted an embodied perspective of the mind by integrating first-person experiential and third-person ...
Functional connectivity drifts during sleep as a marker of fluctuations in the level of consciousness [0.03%]
睡眠期间功能连接逐渐减弱作为意识水平波动的标志

During the wake-sleep cycle, consciousness waxes and wanes, and this is thought to be reflected in varying levels of integration between brain areas. Recent studies challenged the notion that consciousness is homogeneously present or absent...

Psychedelic compounds significantly reshape conscious perception, yet the implications of these alterations for complex visual-guided behaviors remain poorly understood. We investigated how psilocybin modulates visual salience processing du...
Brain-body interactions associated with the transition from mind wandering to awareness of its occurrence [0.03%]
与从走神过渡到意识到走神发生相关的脑体相互作用

Our thoughts are inherently dynamic and often wander far from our current situation (mind wandering, MW). Although previous research revealed that brain regions involved in arousal regulation modulate neural dynamics to facilitate the trans...
Qualia structures collapse for geometric shapes, but not faces, when spatial attention is withdrawn [0.03%]

Top-down attentional amplification is often assumed to affect 'what' we see, that is, the contents of conscious experience. Previously, this claim has been examined by studies that manipulated attention and characterized conscious perceptio...

Understanding the neural correlates of consciousness remains a central challenge in neuroscience. In this study, we explore the potential of neural field theory (NFT) as a computational framework for representing consciousness states. While...
