Predictive processing theories, especially active inference, have been proposed as a way to reconcile embodied and traditional cognitive science. This analysis argues that most active-inference accounts rely on weak or trivial conceptions of embodiment, while stronger claims do not follow from the framework itself. A more compelling version of embodied active inference is motivated by taking a diachronic view of how rhythmic physiological activity shapes neural development before birth. The visceral afferent training hypothesis proposes that early-emerging physiological processes, particularly from the cardiovascular system, are essential for configuring cognitive architecture. Three candidate mechanisms are suggested: activity-dependent neuronal development, periodic signal modeling, and oscillatory network coordination.

Psilocybin treatment in rats performing a reversal learning task led to more rewards through increased task engagement, driven by changes in forgetting rates and reduced loss aversion. Computational modeling suggests psilocybin may induce an optimism bias by altering how beliefs are updated, which could have implications for clinical conditions marked by pessimism.

Subjective experience is multifaceted, making it hard for traditional neuroscientific theories of consciousness to be compared because each focuses on different aspects like perceptual awareness or global states. This work instead starts from active inference, a first-principles framework that models behavior as approximate Bayesian inference, and builds a minimal theory of consciousness from shared features of computational models derived under active inference. By reviewing studies that apply active inference models to consciousness, the authors identify a small set of theoretical commitments implicit in these models, pointing toward a minimal and testable theory of consciousness.

Mind blanking—a state of apparent mental emptiness—produces distinct brain signatures that separate it from mind wandering and focused attention. In 62 participants performing a sustained attention task, mind blanking was associated with behavioral lapses, reduced fast brain oscillations and complexity over posterior electrodes, and decreased long-range connectivity compared to both mind wandering and on-task states. Event-related potentials showed disrupted visual processing beginning 200 milliseconds after a stimulus, suggesting a breakdown in conscious access to sensory information. Brain activity patterns predicted mental states on individual trials, revealing dynamics that subjective reports alone miss. These findings indicate that being awake does not guarantee consciousness of something; mind blanking reflects genuine gaps in the stream of thought, arising from disruptions in generating or accessing thought content.

Mindfulness meditation, which trains attention on sensory experiences with nonjudgmental awareness, is thought to sharpen sensory processing and reduce top-down expectations. This study measured forward and backward traveling cortical alpha waves—proposed to reflect bottom-up inhibition and top-down inhibition, respectively—using electroencephalography in meditators and nonmeditators. During eyes-closed resting (97 participants) and a visual Go/No-go task (126 participants), meditators showed stronger forward traveling waves than nonmeditators in both conditions, and weaker backward traveling waves during rest. These neural differences may underlie enhanced attention and reduced mind-wandering associated with meditation, supporting models where mental training increases sensory awareness.

Three theories of consciousness—Integrated Information Theory, Neurorepresentationalism, and Active Inference—are compared and contrasted in a structured adversarial collaboration. The review presents each theory's core claims, the phenomena they explain, their explanatory approaches, and methodological strategies. It outlines key hypotheses to be tested across multi-site experiments, discusses observations that would support or challenge each theory, and describes how data from disparate experiments can be formally integrated to quantify evidential support. The work also provides meta-scientific insights into the mechanics of adversarial collaboration and theory-testing, including how theories may be evaluated by the scientific progress they deliver.
