Computational spirits: a neuroscientific account of psychedelic entity encounters.

Neuroscience of Consciousness 2026 Jonas Mago, George Deane, Lars Sandved-Smith et al.

Under the influence of psychedelics, people often report encountering "entities" who seem to have their own autonomous agency. Depending on the cultural milieu, these entities are reported to take a variety of forms, including spirits, elves, ancestors, or fragments of the self. Encounters with such beings hold a central place in many traditions of psychedelic practice around the world. And...

A Rosetta Stone hypothesis for neurophenomenology: mathematical predictions from predictive processing.

Neuroscience of Consciousness 2026 Lancelot da Costa, Anil K. Seth, Karl Friston et al.

Consciousness science faces the challenge of bridging first-person experience with third-person empirical measurements. Neurophenomenology aims to build such 'generative passages' connecting the content of experience with behavioural and neuroscientific data. However, the mathematical machinery for such bridges remains underdeveloped. Here we develop a Rosetta Stone hypothesis from predictive...

How do inner screens enable imaginative experience? Applying the free-energy principle directly to the study of conscious experience.

Neuroscience of Consciousness 2025 Chris Fields, Mahault Albarracin, Karl Friston et al. 6 citations

This paper examines the constraints that the free-energy principle (FEP) places on possible model of consciousness, particularly models of attentional control and imaginative experiences, including episodic memory and planning. We first rehearse the classical and quantum formulations of the FEP, focusing on their application to multi-component systems, in which only some components interact...

From Generative Models to Generative Passages: A Computational Approach to (Neuro) Phenomenology.

Review of Philosophy and Psychology 2022 Maxwell J D Ramstead, Anil K. Seth, Casper Hesp et al. 75 citations

This paper presents a version of neurophenomenology based on generative modelling techniques developed in computational neuroscience and biology. Our approach can be described as computational phenomenology because it applies methods originally developed in computational modelling to provide a formal model of the descriptions of lived experience in the phenomenological tradition of philosophy...

Towards a computational phenomenology of mental action: modelling meta-awareness and attentional control with deep parametric active inference.

Neuroscience of Consciousness 2021 Lars Sandved-Smith, Casper Hesp, Jérémie Mattout et al. 116 citations

Meta-awareness refers to the capacity to explicitly notice the current content of consciousness and has been identified as a key component for the successful control of cognitive states, such as the deliberate direction of attention. This paper proposes a formal model of meta-awareness and attentional control using hierarchical active inference. To do so, we cast mental action as policy...

Thinking through other minds: A variational approach to cognition and culture.

The Behavioral and brain sciences May 30, 2019 Samuel P. L. Veissière, Axel Constant, Maxwell J D Ramstead et al. 362 citations

The processes underwriting the acquisition of culture remain unclear. How are shared habits, norms, and expectations learned and maintained with precision and reliability across large-scale sociocultural ensembles? Is there a unifying account of the mechanisms involved in the acquisition of culture? Notions such as "shared expectations," the "selective patterning of attention and behaviour,"...
