Pterosaurs were the first vertebrates to evolve powered flight1 and comprised one of the main evolutionary radiations in terrestrial ecosystems of the Mesozoic era (approximately 252–66 million years ago), but their origin has remained an unresolved enigma in palaeontology since the nineteenth century2,3,4. These flying reptiles have been hypothesized to be the close relatives of a wide...

Intracortical inhibition increases during postural task execution in response to balance training

Mouthon, Audrey ; Taube, Wolfgang

In: Neuroscience, 2019, vol. 401, p. 35–42

Intracortical inhibitory modulation seems crucial for an intact motor control and motor learning. However, the influence of long(er) term training on short-interval intracortical inhibition (SICI) is scarcely investigated. With respect to balance, it was previously shown that with increasing postural task difficulty, SICI decreased but the effect of balance training (BT) is unknown. The...

Aging effects on prefrontal cortex oxygenation in a posture-cognition dual-task: an fNIRS pilot study

Marusic, Uros ; Taube, Wolfgang ; Morrison, Shawnda A. ; Biasutti, Lea ; Grassi, Bruno ; Pauw, Kevin De ; Meeusen, Romain ; Pisot, Rado ; Ruffieux, Jan

In: European Review of Aging and Physical Activity, 2019, vol. 16, no. 1, p. 2

The aging process alters upright posture and locomotion control from an automatically processed to a more cortically controlled one. The present study investigated a postural-cognitive dual-task paradigm in young and older adults using functional Near- Infrared Spectroscopy (fNIRS).Methods: Twenty healthy participants (10 older adults 72 ± 3 y, 10 young adults 23 ± 3 y) performed a...

Alterations in the cortical control of standing posture during varying levels of postural threat and task difficulty

Tokuno, Craig D. ; Keller, Martin ; Carpenter, Mark G. ; Márquez, Gonzalo ; Taube, Wolfgang

In: Journal of Neurophysiology, 2018, vol. 120, no. 3, p. 1010–1016

Cortical excitability increases during the performance of more difficult postural tasks. However, it is possible that changes in postural threat associated with more difficult tasks may in themselves lead to alterations in the neural strategies underlying postural control. Therefore, the purpose of this study was to examine whether changes in postural threat are responsible for the...

Accompagnement partagé dans une formation en alternance à l’enseignement instrumental = Supporting the training of instrument teaching in a shared way within a dual training

Giovannini-Cartulano, Valentina ; Coen, Pierre-François ; Güsewell, Angelika ; Paukovics, Elsa

In: Formation et profession : Revue scientifique internationale en éducation, 2018, vol. 26, no. 3, p. 43-56

Conducted in a Swiss music university along with the implementation of a new training system for a master’s course of instrument teaching, this research aims to highlight how the beliefs about support by the different actors involved (pedagogy teachers, didactic teachers as well as practical training teachers) shape their practices, postures and accompaniment behaviors of the...

Age-dependent adaptations to anticipated and non-anticipated perturbations after balance training in children

Wälchli, Michael ; Keller, Martin ; Ruffieux, Jan ; Mouthon, Audrey ; Taube, Wolfgang

In: Human Movement Science, 2018, vol. 59, p. 170–177

Postural control undergoes rapid changes during child development. However, the influence of balance training (BT) on the compensation of perturbations has not yet been investigated in children. For this purpose, young (6.7 ± 0.6 years) and old children (12.0 ± 0.4 years) were exposed to externally induced anticipated (direction known) and non-anticipated (direction unknown)...
