Use of waggle dance information in honey bees is linked to gene expression in the antennae, but not in the brain.

2021

AbstractCommunication is essential for social animals, but deciding how to utilize information provided by conspecifics is a complex process that depends on environmental and intrinsic factors. Honey bees use a unique form of communication, the waggle dance, to inform nestmates about the location of food sources. However, as in many other animals, experienced individuals often ignore this social information and prefer to rely on prior experiences, i.e. private information. The neurosensory factors that drive the decision to use social information are not yet understood. Here we test whether the decision to use social dance information or private information is linked to gene expression diff…

Honeybees use the waggle dance to share information about food-site locations with nestmates. However, the importance of this behavior in colony foraging success remains unclear. We tested whether spatial dance information affects colony foraging success in a human-modified temperate environment by comparing colonies with oriented and disoriented dances. Notably, colonies with disoriented dances had greater foraging success. Over time, bees exposed to disoriented dances showed reduced interest in dancing nestmates. This may explain why disoriented colonies had a higher foraging rate than oriented colonies, as bees did not waste time waiting for information. This change in information-use st…

Octopamine and dopamine mediate waggle dance following and information use in honeybees.

2020

Honeybees can be directed to profitable food sources by following waggle dances performed by other bees. Followers can often choose between using this social information or relying on memories about food sources they have visited in the past, so-called private information. While the circumstances that favour the use of either social or private information have received considerable attention, still little is known about the neurophysiological basis of information use. We hypothesized that octopamine and dopamine, two biogenic amines with important functions in reward signalling and learning, affect dance use in honeybees. We orally administered octopamine and dopamine when bees collected fo…

Musical training predicts cerebello-hippocampal coupling during music listening.

2018

Cerebello-hippocampal interactions occur during accurate spatiotemporal prediction of movements. In the context of music listening, differences in cerebello-hippocampal functional connectivity may result from differences in predictive listening accuracy. Using functional MRI, we studied differences in this network between 18 musicians and 18 nonmusicians while they listened to music. Musicians possess a predictive listening advantage over nonmusicians, facilitated by strengthened coupling between produced and heard sounds through lifelong musical experience. Thus, we hypothesized that musicians would exhibit greater functional connectivity than nonmusicians as a marker of accurate online pr…

Tactics of invisibility : How people in vulnerable positions make datafied everyday life livable

2022

Various data platforms force the individual into constant presence and visibility. However, the ways in which datafied environments relate to experienced vulnerabilities in our everyday lives remain unclear. Through diaries produced by and interviews with participants from three groups who occupy presumably vulnerable positions and who currently live in Finland, we explore the ways in which people challenge expectations and prior assumptions related to forced visibility. Using the concept of tactics developed by de Certeau, we aim to understand how individuals make everyday surveillance culture livable through what we call tactics of invisibility. Based on our analysis, we identify three k…

Dance on cortex: enhanced theta synchrony in experts when watching a dance piece

2018

When watching performing arts, a wide and complex network of brain processes emerge. These processes can be shaped by professional expertise. When compared to laymen, dancers have enhanced processes in observation of short dance movement and listening to music. But how do the cortical processes differ in musicians and dancers when watching an audio-visual dance performance? In our study, we presented the participants long excerpts from the contemporary dance choreography of Carmen. During multimodal movement of a dancer, theta phase synchrony over the fronto-central electrodes was stronger in dancers when compared to musicians and laymen. In addition, alpha synchrony was decreased in all gr…

Women’s Foot Health–Related Quality of Life in Ballet Dancers and Nondancers

2020

Background: Prevalence and severity of symptoms related to muscle and joint pain seem to be high in most dancers. Hypothesis: There will be a worse quality of life related to foot health for ballet dancers compared with nondancers. Study Design: Case-control study. Level of Evidence: Level 4. Methods: A sample of 156 women was recruited from a clinic of podiatric medicine and surgery. Self-reported data were measured by the Foot Health Status Questionnaire (FHSQ), which has 33 questions that assess 8 health domains of the feet and general health, namely, foot pain, foot function, general foot health, footwear, general health, physical activity, social capacity, and vigor. Results: Statistic…

Towards an Aesthetic of „Straniety” in Postmodern and Contemporary Dance

2021

Abstract The complicated physiognomy of dance in the XX-th and XXI-th century obviously exeedes the stable marks of „beauty” as an aesthetic category, by extending the limits of imaginary and techniques of artistic productions beyond any restraints. Both form and artistic expressions become suitable for specific interpretations, through the instruments and postmodern categories. The argumentation frequently refer to three moments of avantgardes, swiftly mentioning the reform’s beginings on the european artistic environment as a starting point, and underlying the Black Montain College phenomenon, and its consequences through the 80-ties and after. The fluctuations of artistic objectives are …

Living autobiographically: Concepts of aging and artistic expression in painting and modern dance.

2016

This article discusses the ways in which artists have incorporated or failed to incorporate the aging process of their bodies into their art. Using Russian ballet dancer Mikhail Baryshnikov and the French painter Claude Monet as cases in point, we explore situations in which physical changes brought about by aging compromises artists' ability to engage with their artistic medium. Connecting Monet's oeuvre and Baryshnikov's dance performances to life writing accounts, we draw on John Paul Eakin's concept of "living autobiographically": In this vein, life writing research does not only have to take into account concepts of identity as they emerge from life writing narratives, but it also need…

Participation Profiles and Socialisation into Dance Among Non‐Professional Dancers

1997

Abstract The study was designed to determine how individuals become socialised into folk, competitive ballroom, ballet and modern dance through an investigation of background variables, the influence of significant others and the participation profiles of dancers, and the identification of those socialization and involvement variables that best discriminate among different groups of dancers. The subjects were 308 adolescent and adult dancers of at least 16 years of age who had pursued their main dance form for a minimum of three years. The data were collected by questionnaire, supplemented with some additional data gathered through personal interviews. Differences between the four dance gro…
