  1. Is predictive processing a theory of perceptual consciousness?Tomas Marvan & Marek Havlík - 2021 - New Ideas in Psychology 61 (21).
    Predictive Processing theory, hotly debated in neuroscience, psychology and philosophy, promises to explain a number of perceptual and cognitive phenomena in a simple and elegant manner. In some of its versions, the theory is ambitiously advertised as a new theory of conscious perception. The task of this paper is to assess whether this claim is realistic. We will be arguing that the Predictive Processing theory cannot explain the transition from unconscious to conscious perception in its proprietary terms. The explanations offer (...)

  2. Apical amplification—a cellular mechanism of conscious perception?Tomas Marvan, Michal Polák, Talis Bachmann & William A. Phillips - 2021 - Neuroscience of Consciousness 7 (2):1-17.
    We present a theoretical view of the cellular foundations for network-level processes involved in producing our conscious experience. Inputs to apical synapses in layer 1 of a large subset of neocortical cells are summed at an integration zone near the top of their apical trunk. These inputs come from diverse sources and provide a context within which the transmission of information abstracted from sensory input to their basal and perisomatic synapses can be amplified when relevant. We argue that apical amplification (...)

  3. Cellular Mechanisms of Cooperative Context-Sensitive Predictive Inference.Tomas Marvan & William Alfred Phillips - 2024 - Current Research in Neurobiology 6.
    We argue that prediction success maximization is a basic objective of cognition and cortex, that it is compatible with but distinct from prediction error minimization, that neither objective requires subtractive coding, that there is clear neurobiological evidence for the amplification of predicted signals, and that we are unconvinced by evidence proposed in support of subtractive coding. We outline recent discoveries showing that pyramidal cells on which our cognitive capabilities depend usually transmit information about input to their basal dendrites and amplify (...)

  4. Generality and content-specificity in the study of the neural correlates of perceptual consciousness.Tomas Marvan & Michal Polák - 2020 - Philosophy and the Mind Sciences 1 (2).
    The present paper was written as a contribution to ongoing methodological debates within the NCC project. We focus on the neural correlates of conscious perceptual episodes. Our claim is that the NCC notion, as applied to conscious perceptual episodes, needs to be reconceptualized. It mixes together the processing related to the perceived contents and the neural substrate of consciousness proper, i.e. mechanisms making the perceptual contents conscious. We thus propose that the perceptual NCC be divided into two constitutive subnotions. The (...)

  5. Was Wegner Rejecting Mental Causality?Tomas Marvan - manuscript
    Abstract: Daniel Wegner’s theory of apparent mental causation is often misread. His aim was not to question the causal effectiveness of conscious mental states like intentions. Rather, he attempted to show that our subjective sense of agency is not a completely reliable indicator of the actual causality of action, and needs to be replaced by more objective means of inquiry.
