The relationship between conscious experience and brain activity has intrigued scientists philosophers for centuries. In the last decades, several theories have suggested different accounts these relationships. These developed in parallel, with little to no cross-talk among them. To advance research on consciousness, we established an adversarial collaboration proponents of two major field, Global Neuronal Workspace Integrated Information Theory. Together, devised preregistered experiments...
Summary Different theories explain how subjective experience arises from brain activity 1,2 . These have independently accrued evidence, yet, confirmation bias and dependence on design choices hamper progress in the field 3 Here, we present an open science adversarial collaboration which directly juxtaposes Integrated Information Theory (IIT) 4,5 Global Neuronal Workspace (GNWT) 6–10 , employing a theory-neutral consortium approach 11,12 We investigate neural correlates of content duration...
Prediction plays a crucial role in perception, as prominently suggested by predictive coding theories. However, the exact form and mechanism of modulations sensory processing remain unclear, with some studies reporting downregulation response for predictable input whereas others observed an enhanced response. In similar vein, has been linked to either sharpening or dampening representation, which are opposite nature. present study, we set out investigate neural consequences perceptual...
Perception and behavior can be guided by predictions, which are often based on learned statistical regularities. Neural responses to expected stimuli frequently found attenuated after learning. However, whether this sensory attenuation following learning occurs automatically or depends attention remains unknown. In the present fMRI study, we exposed human volunteers sequentially presented object stimuli, in first predicted identity of second object. We observed a reliable neural activity for...
Visual context facilitates perception, but how this is neurally implemented remains unclear. One example of contextual facilitation found in reading, where letters are more easily identified when embedded a word. Bottom-up models explain word advantage as post-perceptual decision bias, while top-down propose that contexts enhance perception itself. Here, we arbitrate between these accounts by presenting words and nonwords probing the representational fidelity individual using functional...

Avoiding distraction by salient yet irrelevant stimuli is critical when accomplishing daily tasks. One possible mechanism to accomplish this suppressing that may be distracting such they no longer compete for attention. While the behavioral benefits of distractor suppression are well-established, its neural underpinnings not fully understood. In an fMRI study, we examined whether and how sensory responses in early visual areas show signs after incidental learning spatial statistical...

Recent provide evidence that errors, even early areas,may reflect high-level surprise, offering new insights into role predictive processing thebrain beyond classical accounts redundancy reduction

Abstract Expectations, derived from previous experience, can help in making perception faster, more reliable and informative. A key neural signature of perceptual expectations is expectation suppression, an attenuated response to expected compared with unexpected stimuli. While suppression has been reported using a variety paradigms recording methods, it remains unclear what modulation underlies this attenuation. Sharpening models propose that populations tuned away stimulus are particularly...
The brain has the extraordinary capacity to construct predictive models of environment by internalizing statistical regularities in sensory inputs. resulting expectations shape how we perceive and react world; at neural level, this relates decreased responses expected than unexpected stimuli (“expectation suppression”). Crucially, may need revision as context changes. However, existing research often neglected issue. Further, it is unclear whether contextual revisions apply selectively...
A crucial ability of the human brain is to learn and exploit probabilistic associations between stimuli facilitate perception behavior by predicting future events. Although studies have shown how perceptual relationships are used predict sensory inputs, relational knowledge often concepts rather than percepts (e.g., we learned associate cats with dogs, specific images dogs). Here, asked if responses visual input may be modulated predictions derived from conceptual associations. To this end...
Both spatial and temporal context play an important role in visual perception behavior. Humans can extract statistical regularities from both forms of to help process the present construct expectations about future. Numerous studies have found reduced neural responses expected stimuli compared with unexpected stimuli, for regularities. However, it is largely unclear whether how these interact. In current fMRI study, 33 human volunteers were exposed pairs object that could be or surprising...

Abstract Perception and behaviour are significantly moulded by expectations derived from our prior knowledge. Hierarchical predictive processing theories provide a principled account of the neural mechanisms underpinning these processes, casting perception as hierarchical inference process. While numerous studies have shown stronger activity for surprising inputs, in line with this account, it is unclear what predictions made across cortical hierarchy, therefore kind surprise drives...
