Undue pathologization is a major risk for global health, especially when diagnoses rely exclusively on Western nosology. This article focuses on the clinical conflation between involuntary mass possession and conversion disorder. Originally, the diagnosis of ‘‘conversion disorder’’ evolved from the notion of hysteria. Even though the category of hysteria disappeared from psychiatry many decades ago, some of its undergirding assumptions have survived
under the new label of conversion. Namely, the assumption that hysteria/conversion is caused by repressed sexual desire is still implicit in widespread explanatory models for mass possession worldwide. Drawing upon an ethnography of demonic possession (grisi siknis) among the Afro-Indigenous Miskitos of Nicaragua, I argue that (1) the label of conversion is eurocentric and inappropriate for mass possession; and (2) emic perspectives on mass possession offer a critical counterpoint to rethink
Euro-American and globalized understandings of embodiment and desire.

In the social sciences, instead, there is still a lack of theories explaining how cultures shape the way we listen to our bodies. Fyssen Foundation enabled a cross-disciplinary research in anthropology, cognitive sciences and technology studies, conducted at Northwestern University. This research integrates multiple datasets, spanning from an ethnography of demonic possession in Nicaragua to an ongoing inquiry on medically unexplained symptoms in the US. Far from being exclusively a physiological matter, interoception is at the core of the formation of shared representations. This research bridges the gap between the microlevel of the cognition of inner sensations (1) and the macrolevel of the formation of beliefs and shared representations that we call "culture" (2).

Functional Neurological Disorder (FND), otherwise known as Conversion Disorder, is characterized ... more Functional Neurological Disorder (FND), otherwise known as Conversion Disorder, is characterized by abnormal
sensory or motor symptoms that are determined to be “incompatible” with neurological disease. FND patients
are a challenge for contemporary medicine. They experience high levels of distress, disability, and social isolation,
yet a large proportion of those treated do not get better. Patients with FNDs are often misdiagnosed and
suffer from stigma, dysfunctional medical encounters and scarcity of adequate treatments. In this paper we argue
that an anthropological understanding of these phenomena is needed for improving diagnosis and therapies. We
argue that cultural meaning is pivotal in the development of FND on three levels. 1) The embodiment of cultural
models, as shared representations and beliefs about illnesses shape the manifestation of symptoms and the meanings
of sensations; 2) The socialization of personal trauma and chronic stress, as the way in which individuals
are socially primed to cope or to reframe personal trauma and chronic stress affects bodily symptoms; 3) Moral
judgment, as stigma and ethical evaluations of symptoms impact coping abilities and resilience. In particular,
we focus on the disorder known as PNES (Psychogenic-Non-Epileptic Seizure) to show how cultural meaning
co-determines the development of such seizures. We introduce the notion of interoceptive affordances to account
for the cultural scaffolding of patients’ bodily experiences. Finally, we suggest that effective treatments of FND
must act upon meaning in all of its aspects, and treatment adequacy must be assessed according to the cultural
diversity of patients.

In the first part of this article I focus on an ethnographic case: grisi siknis, an hallucinatory trance seizure diffused among the Miskitos and other populations of Central America. According to local theories, grisi siknis seizure is a transmissible syndrome, usually affecting crowds of young people. The seizure‟s experience is disruptive, as it produces cognitive and metacognitive impairments. By exploring the social interactions which are constitutive of grisi siknis, I claim the need to elaborate interactional models of Altered States of Consciousness Configurations (ASCCs). In order to model ASCCs, I articulate predictive-inferential models of consciousness with pragmatic analyses of interactional devices. Finally, I advance some preliminary propositions towards an anthropology of consciousness suitable for describing societies as collective fields of inter-subjective psycho-physiological influences.

A grisi siknis attack triggers an aggressive/self-aggressive behaviour accompanied by recurrent hallucinations. Because of their pathogenic effect, visual images related to grisi siknis attacks are rarely represented. However, they form a coherent and sophisticated iconic repertory. By adopting an experimental ethnographic methodology I proposed to a group of grisi siknis patients to draw on paper their hallucinatory visions. After questioning the nature of these images – in the interplay between representation, somatic residues and shared imaginative matrixes – I propose the notion of implicit iconography to account for such kind of traditions where an iconic repertory is transmitted without external support.

This volume explores, from a comparative perspective, the nature of the relationship between these images and the cultures that inspire them or are inspired by them. Modes of attribution of agentivity, ontological status of images, processes of constitution of identities and collectives, relations between figuration, memory and present are all themes to which the anthropological study of visionary images offers a significant contribution.

If interoceptive ability varies with respect to cultural, social, and gender factors as well as specific bodily conditions and training, the ways in which interoception is shaped by societies remain widely underexplored. In this talk I address this issue through the lens of grisi siknis, an involuntary, hallucinatory trance attack diffused among the Miskitos of Nicaragua and Honduras. Grisi siknis is perceived by the Miskitos as a contagious illness affecting the whole mind and body, in particular the gastrointestinal and reproductive systems among girls and young indigenous women. Drawing upon an analysis of how shared meanings as “Evil spirits” and “spiritual contagion” are internalized and associated with dysfunctional bodily processes, I sketch a Bayesian (predictive-inferential) model of the looping between emotionally negative hallucinations and distorted interoception, explaining the psycho-social aspects of somatization. By integrating insights from anthropology, neurocognitive sciences, biology and psychophysiology, I propose a general model of the bio-looping between interoception and self-consciousness susceptible to be transposed in diverse cultural contexts. Finally, I advance some reflections on the ways in which the interplay between interoception and self-consciousness influences people’s sense(s) of reality and shared ontologies.

Une attaque de grisi siknis déclenche un comportement agressif/auto-agressif associé à une série d'hallucinations récurrentes. À cause de leur potentiel pathogène, les images visuelles associées aux attaques de grisi siknis sont rarement représentées.

Grisi siknis is a Miskito calque of the English expression « crazy sickness ». Behind this secretive label lies a series of mass trance seizures that have been happening for more than fifty years in the Moskitia region, between Eastern Nicaragua and Honduras. Grisi siknis is an involuntary trance attack, mainly affecting young Miskito women, an afro-indigenous population whose language belongs to the Misumalpa family. During the trance, those attacked by grisi siknis (lasa praprukra) show an aggressive/auto-aggressive behaviour associated with repeated hallucinations, which is generally interpreted as the attack of an evil spirit. The spread of the disease is seen by those affected as a dangerous epidemic which therapies are still controversial. Nevertheless, the lasa praprukra behaviour presents a certain degree of ritualization. The main goal of this study, which relies on one year of ethnographic research in Nicaragua, is to describe grisi siknis propagation by analysing its interactional dynamics and the constitution of the imagery impulsing its spread. The iconic imagery of grisi siknis has been studied by proposing to patients to draw their hallucinatory contents. As it shares some analogies with local shamanic treatment, this practice has been apprehended as a form of therapy. The iconographic corpus of grisi siknis drawings is analysed both in representation and in agentive embodied imagery terms. Secondly, this thesis describes the neurocognitive processes behind the seizure by sketching a Bayesian model of the induction of hallucinations in healthy subjects without psychotropic intake. Finally, the social status of lasa praprukra is compared to those of some local ritual specialists as shamans and healers. An important place is accorded to the fluctuating ontology of the spirits mobilized during the trance, as well as to the role held by metacognition in the psycho-physiological modifications encouraging spirits experience and belief.

Grisi siknis is a Miskito calque of the English expression « crazy sickness ». Behind this secretive label lies a series of mass trance seizures that have been happening for more than fifty years in the Moskitia region, between Eastern Nicaragua and Honduras. Grisi siknis is an involuntary trance attack, mainly affecting young Miskito women, an afro-indigenous population whose language belongs to the Misumalpa family. During the trance, those attacked by grisi siknis (lasa praprukra) show an aggressive/auto-aggressive behaviour associated with repeated hallucinations, which is generally interpreted as the attack of an evil spirit. The spread of the disease is seen by those affected as a dangerous epidemic which therapies are still controversial. Nevertheless, the lasa praprukra behaviour presents a certain degree of ritualization. The main goal of this study, which relies on one year of ethnographic research in Nicaragua, is to describe grisi siknis propagation by analysing its interactional dynamics and the constitution of the imagery impulsing its spread. The iconic imagery of grisi siknis has been studied by proposing to patients to draw their hallucinatory contents. As it shares some analogies with local shamanic treatment, this practice has been apprehended as a form of therapy. The iconographic corpus of grisi siknis drawings is analysed both in representation and in agentive embodied imagery terms. Secondly, this thesis describes the neurocognitive processes behind the seizure by sketching a Bayesian model of the induction of hallucinations in healthy subjects without psychotropic intake. Finally, the social status of lasa praprukra is compared to those of some local ritual specialists as shamans and healers. An important place is accorded to the fluctuating ontology of the spirits mobilized during the trance, as well as to the role held by metacognition in the psycho-physiological modifications encouraging spirits experience and belief.
