Free Body

The embodied perspective on music cognition has stressed the central role of the body and body movements in musical meaning formation processes. In the present study, we investigate by means of a behavioral experiment how free body movements in response to music (i.e., action) can be linked to specific linguistic, metaphorical descriptions people use to describe the expressive qualities they perceive in the music (i.e., perception). We introduce a dimensional model based on the Effort/Shape theory of Laban in order to target musical expressivity from an embodied perspective. Also, we investigate whether a coupling between action and perception is dependent on the musical background of the participants (i.e., trained versus untrained). The results show that the physical appearance of the free body movements that participants perform in response to music are reliably linked to the linguistic descriptions of musical expressiveness in terms of the underlying quality. Moreover, this result is found to be independent of the participants’ musical background.

The central role of the body in producing music is hardly debatable. Likewise, the body has always played at least an implicit role in music theory, but has only been raised as a factor in music analysis relatively recently. In this essay I present a brief update of the body in music analysis via case studies, situated in the disciplines of music theory and music cognition, broadly construed. This current trajectory is part of a broader shift away from the musical score as the sole focus for analysis, which admittedly—though, in my view, delightfully—raises a host of challenging epistemological questions surrounding the interaction of performer (production) and listener (perception). While the concomitant research methodologies and technologies may be unfamiliar to scholars trained in humanities disciplines, I advocate for a full embrace of these approaches, either by individual researchers or in the form of cross-disciplinary collaboration.

The Relationship

The work described in this paper interprets the body movements of singers in an attempt to understand the relationships between physical control and the musical material being performed, and the performer's implicit and explicit expressive intentions. The work builds upon a previous literature which has suggested that the relationship between physical execution and the expression of mental states is a subtle and complex one. For instance, performers appear to develop a vocabulary of expressive gestures, yet these gestures – though perceptually discreet – co-exist and are even integrated to become part of the functional movement of playing. Additionally, there is the matter of how both musical and extra-musical concerns are coordinated between performer, co-performers and audience using body movements. A case study shows how, in the interaction between body style, musical expression and communication movements of both an individual and culturally-determined style are used. Many of these performance movements have clear functions and meanings: to communicate expressive intention (for instance, a sudden surge forwards to facilitate the execution of a loud musical passage, or a high curving hand gesture to link sections of the music during a pause); to communicate to the audience or co-performers a need for co-ordination or participation (for example, nodding the head to indicate “now” for the audience to join in a chorus of a song; or exchanging glances for the co-performer to take over a solo); to signal extra-musical concerns (for example, gesturing to the audience to remain quiet); and to present information about the performer's personality, with their individualized characteristics providing important cues (muted contained gestures, or large extravagant gestures, for example); to show off to the audience. From these results a theory is developed to explain how gestural elements help to make a performance meaningful.

The intrinsic function of the brain stem–spinal cord networks eliciting the locomotor synergy is well described in the lamprey—a vertebrate model system. This study addresses the role of tectum in integrating eye, body orientation, and locomotor movements as in steering and goal-directed behavior. Electrical stimuli were applied to different areas within the optic tectum in head-restrained semi-intact lampreys ( n = 40). Motions of the eyes and body were recorded simultaneously (videotaped). Brief pulse trains (<0.5 s) elicited only eye movements, but with longer stimuli (>0.5 s) lateral bending movements of the body (orientation movements) were added, and with even longer stimuli locomotor movements were initiated. Depending on the tectal area stimulated, four characteristic response patterns were observed. In a lateral area conjugate horizontal eye movements combined with lateral bending movements of the body and locomotor movements were elicited, depending on stimulus duration. The amplitude of the eye movement and bending movements was site specific within this region. In a rostromedial area, bilateral downward vertical eye movements occurred. In a caudomedial tectal area, large-amplitude undulatory body movements akin to struggling behavior were elicited, combined with large-amplitude eye movements that were antiphasic to the body movements. The alternating eye movements were not dependent on vestibuloocular reflexes. Finally, in a caudolateral area locomotor movements without eye or bending movements could be elicited. These results show that tectum can provide integrated motor responses of eye, body orientation, and locomotion of the type that would be required in goal-directed locomotion.

The study is based on the theoretical-methodological reference of the Historical-Cultural Perspective, in particular, in the studies of Vigotski that emphasize the beginning role of language for human development. About the children with disabilities, he considers that they develop a new way of understanding and relating, and for this reason, in dealing with them, the boundary barriers of disability (the insufficiencies) cannot be walls that prevent action of the teacher. This, in turn, needs to be attentive to the compensatory ways established in social relationship. Based on these ideas, this study considers that children with ASD have their development linked to favorable social conditions. Fieldwork was carried out in the second half of 2016, focusing on pedagogical activities developed between the student and the teacher-researcher. The situations were videotaped and registered in field diaries; the filming was transcribed in full, considering the body movements, expressions and gestures of the participants. In the course of fieldwork, the teacher-researcher reflects on his practice, changes the way he relates to the boy, and in this movement of exchanges and (re)constructions, the student also changes. The analysis reveals that the teacher-student relationship, mediated by the word, constituted as a space for (trans)formation, elaboration and development of both, student and teacher.

Planarians exhibit traits of cephalization but are unique among bilaterians in that they ingest food by means of goal-directed movements of a trunk-positioned pharynx, following protrusion of the pharynx out of the body, raising the question of how planarians control such a complex set of body movements for achieving robust feeding. Here, we use the freshwater planarian Dugesia japonica to show that an isolated pharynx amputated from the planarian body self-directedly executes its entire sequence of feeding functions: food sensing, approach, decisions about ingestion, and intake. Gene-specific silencing experiments by RNA interference demonstrated that the pharyngeal nervous system (PhNS) is required not only for feeding functions of the pharynx itself but also for food-localization movements of individual animals, presumably via communication with the brain. These findings reveal an unexpected central role of the PhNS in the linkage between unique morphological phenotypes and feeding behavior in planarians.

Dietary polyphenols have been shown to scavenge free radicals, modulating cellular redox transcription factors in different in vitro and ex vivo models. Dietary intervention studies have shown that consumption of plant foods modulates plasma Non-Enzymatic Antioxidant Capacity (NEAC), a biomarker of the endogenous antioxidant network, in human subjects. However, the identification of the molecules responsible for this effect are yet to be obtained and evidences of an antioxidant in vivo action of polyphenols are conflicting. There is a clear discrepancy between polyphenols (PP) concentration in body fluids and the extent of increase of plasma NEAC. The low degree of absorption and the extensive metabolism of PP within the body have raised questions about their contribution to the endogenous antioxidant network. This work will discuss the role of polyphenols from galenic preparation, food extracts, and selected dietary sources as modulators of plasma NEAC in humans.

AbstractThis paper introduces some levels at which the computer has been incorporated in the research into the basis of electrocardiography. The emphasis lies on the modeling of the heart as an electrical current generator and of the properties of the body as a volume conductor, both playing a major role in the shaping of the electrocardiographic waveforms recorded at the body surface. It is claimed that the Forward-Problem of electrocardiography is no longer a problem. Several source models of cardiac electrical activity are considered, one of which can be directly interpreted in terms of the underlying electrophysiology (the depolarization sequence of the ventricles). The importance of using tailored rather than textbook geometry in inverse procedures is stressed.

Pseudomonas aeruginosa is a widely represented species of bacteria possessing of a pathogenic potential. This infectious agent is causing wound infections, fibrotic cystitis, fibrosing pneumonia, bacterial sepsis, etc. The microorganism is highly resistant to antiseptics, disinfectants, immune system responses of the body. The responses of a quorum sense of this kind of bacteria ensure the inclusion of many pathogenicity factors. The analysis of the scientific literature made it possible to formulate four questions concerning the role of biofilms for the adaptation of P. aeruginosa to adverse environmental factors: Is another person appears to be predominantly of a source an etiological agent or the source of P. aeruginosa infection in the environment? Does the formation of biofilms influence on the antibiotic resistance? How the antagonistic activity of microorganisms is realized in biofilm form? What is the main function of biofilms in the functioning of bacteria? A hypothesis has been put forward the effect of biofilms on the increase of antibiotic resistance of bacteria and, in particular, P. aeruginosa to be secondary in charcter. It is more likely a biofilmboth to fulfill the function of storing nutrients and provide topical competition in the face of food scarcity. In connection with the incompatibility of the molecular radii of most antibiotics and pores in biofilm, biofilm is doubtful to be capable of performing a barrier function for protecting against antibiotics. However, with respect to antibodies and immunocompetent cells, the barrier function is beyond doubt. The biofilm is more likely to fulfill the function of storing nutrients and providing topical competition in conditions of scarcity of food resources.

This article investigates the ways in which the work of The Body Politic (TBP), the first major lesbian and gay newspaper in Canada, comes to be commemorated in queer publics and how it figures in the memories of those who were involved in producing the paper. In revisiting a critical point in the history of TBP from 1985 when controversy erupted over race and racism within the editorial collective, this discussion considers the role of memory in the reproduction of whiteness and in the rupture of standard narratives about the past. As the controversy continues to haunt contemporary queer activism in Canada, the productive work of memory must be considered an essential aspect of how, when and for what reasons the work of TBP comes to be commemorated. By revisiting the events of 1985 and by sifting through interviews with individuals who contributed to the work of TBP, this article complicates the narrative of TBP as a bluntly racist endeavour whilst questioning the white privilege and racially-charged demands that undergird its commemoration. The work of producing and preserving queer history is a vital means of challenging the intentional and strategic erasure of queer existence, but those who engage in such efforts must remain attentive to the unequal terrain of social relations within which remembering forms its objects.
