This paper disputes the theoretical assumptions of mainstream approaches in philosophy of pain, representationalism and imperativism, and advances an enactive approach as an alternative. It begins by identifying three shared assumptions in the mainstream approaches: the internalist assumption, the brain-body assumption, and the semantic assumption. It then articulates an alternative, enactive approach that considers pain as an embodied response to the situation. This approach entails the hypothesis of the sociocultural embeddedness of pain, which states against the brain-body assumption that the (...) intentional character of pain depends on the agent’s sociocultural background. The paper then proceeds to consider two objections. The first questions the empirical basis of this hypothesis. It is argued based on neuroscientific evidence, however, that there is no empirical reason to suppose that the first-order experience of pain is immune to sociocultural influences. The second objection argues that the mainstream approaches can account for sociocultural influences on pain by drawing on the conceptual distinction between narrow and wide content. In response, the semantic conception of pain underpinning the proposal is challenged. Pain experience can occur in pre-reflective, affectively reflective, or cognitively reflective forms, but the semantic conception at most only applies to the last form. The paper concludes that the enactive approach offers a promising alternative framework in philosophy of pain. (shrink)

This paper aims to provide a theoretical framework for explaining the subjective character of pain experience in terms of what we will call ‘embodied predictive processing’. The predictive processing (PP) theory is a family of views that take perception, action, emotion and cognition to all work together in the service of prediction error minimisation. In this paper we propose an embodied perspective on the PP theory we call the ‘embodied predictive processing (EPP) theory. The EPP theory proposes to explain pain (...) in terms of processes distributed across the whole body. The prediction error minimising system that generates pain experience comprises the immune system, the endocrine system, and the autonomic system in continuous causal interaction with pathways spread across the whole neural axis. We will argue that these systems function in a coordinated and coherent manner as a single complex adaptive system to maintain homeostasis. This system, which we refer to as the neural-endocrine-immune (NEI) system, maintains homeostasis through the process of prediction error minimisation. We go on to propose a view of the NEI ensemble as a multiscale nesting of Markov blankets that integrates the smallest scale of the cell to the largest scale of the embodied person in pain. We set out to show how the EPP theory can make sense of how pain experience could be neurobiologically constituted. We take it to be a constraint on the adequacy of a scientific explanation of subjectivity of pain experience that it makes it intelligible how pain can simultaneously be a local sensing of the body, and, at the same time, a more global, all-encompassing attitude towards the environment. Our aim in what follows is to show how the EPP theory can meet this constraint. (shrink)

Previous studies examining EEG and LORETA in patients with chronic pain discovered an overactivation of high theta and low beta power in central regions. MEG studies with healthy subjects correlating evoked nociception ratings and source localization described delta and gamma changes according to two music interventions. Using similar music conditions with chronic pain patients, we examined EEG in response to two different music interventions for pain. To study this process in-depth we conducted a mixed-methods case study approach, based on three (...) clinical cases. Effectiveness of personalized music therapy improvisations versus preferred music on chronic pain was examined with 16 participants. Three patients were randomly selected for follow-up EEG sessions three months post-intervention, where they listened to recordings of the music from the interventions provided during the research. To test the difference of EM versus preferred music, recordings were presented in a block design: silence, their own composed EM, preferred music, and a non-participant’s EM as a control. Participants rated their pain before and after the EEG on a 1–10 scale. We conducted a detailed single case analysis to compare all conditions, as well as a group comparison of entrainment-healing condition versus preferred music condition. Power spectrum and according LORETA distributions focused on expected changes in delta, theta, beta, and gamma frequencies, particularly in sensory-motor and central regions. Intentional moment-by-moment attention on the sounds/music rather than on pain and decreased awareness of pain was experienced from one participant. Corresponding EEG analysis showed accompanying power changes in sensory-motor regions and LORETA projection pointed to insula-related changes during entrainment-pain music. LORETA also indicated involvement of visual-spatial, motor, and language/music improvisation processing in response to his personalized EM which may reflect active recollection of creating the EM. Group-wide analysis showed common brain responses to personalized entrainment-healing music in theta and low beta range in right pre- and post-central gyrus. We observed somatosensory changes consistent with processing pain during entrainment-healing music that were not seen during preferred music. These results may depict top–down neural processes associated with active coping for pain. (shrink)

Abstract. The placebo effect these days is no longer merely the insubstantial, subjective response that some patients have to a sham treatment, like a sugar pill. It has been reconceived as a powerful mind-body phenomenon. Because of this, it has also emerged as a complex reference point in a number of high-stakes conversations about the metaphysical significance of experiences of religious healing, the possible health benefits of being religious, and the feasibility of using double-blind placebo-controlled trials to investigate the efficacy (...) of prayer. In each of these conversations, the placebo effect is always pointing toward some larger issue, serving some larger agenda. The agendas, though, tend to pull in different directions, leading to a situation that feels at once fractured and stalemated. This essay reviews the main areas of interest, and proposes some specific issues where humanistic scholars of religion in particular might be able to introduce constructive and creative new perspectives.
