Muscle fascicle and tendon behavior during human locomotion revisited.
2008
High-speed ultrasonography has revealed that, in human locomotion, the nature of fascicle and tendon length changes varies depending on the task, contraction intensity, and the muscles involved. The findings emphasize that the active fascicles of the gastrocnemius muscle are suddenly stretched, although they are shortening. This short-lasting stretch triggers the stretch reflex, timing of which is dependent on running speed.
Sight-reading expertise: cross-modality integration investigated using eye tracking
2011
International audience; It is often said that experienced musicians are capable of hearing what they read (and vice versa). This suggests that they are able to process and to integrate multimodal information. The present study investigates this issue with an eye-tracking technique. Two groups of musicians chosen on the basis of their level of expertise (experts, non-experts) had to read excerpts of poorly-known classical piano music and play them on a keyboard. The experiment was run in two consecutive phases during which each excerpt was (1) read without playing and (2) sight-read (read and played). In half the conditions, the participants heard the music before the reading phases. The exc…
Relationships between perceived emotions in music and music-induced movement
2012
Listening to music makes us move in various ways. Several factors can affect the characteristics of these movements, including individual factors and musical features. Additionally, music-induced movement may also be shaped by the emotional content of the music, since emotions are an important element of musical expression. This study investigates possible relationships between emotional characteristics of music and music-induced, quasi-spontaneous movement. We recorded music-induced movement of 60 individuals, and computationally extracted features from the movement data. Additionally, the emotional content of the stimuli was assessed in a perceptual experiment. A subsequent correlational …
The influence of rhythmic and spectro-timbral musical features on gait-related movement
2017
Music makes us move, and humans have the universal tendency to synchronise their movements to music. This phenomenon has been used in music therapy to help people with movement disorders regain control over their movements. Rhythmic auditory stimulation has shown promising results in gait rehabilitation in various clinical populations. In healthy populations, various differences have been found between movement while walking to musical and metronome stimuli in terms of stride length. However, insufficient research has been conducted concerning the musical features that could evoke this difference, and which gait-related movements might change under the influence of music. The aim of this mo…
Possibilities of Elementary Musical Lessons for Children Communication Skills
2012
Object of the paper - explore the possibilities of musical lesson for the child for communication skills. The paper was used for theoretical metod - analysis of scientific literature and empirical research method – pedagogical observations of individual and group lessons. Theoretically and practically explored and described possibilities of music lessons for communication skills. The author main conclusions of the study: 1. By participating in the musical play, children are encouraged musical hearing, physical coordination, language development, emotional and social development, communication and independence skills, etc. 2. When creating classesmodels to integrate all the musical creativit…
Predictive error detection in pianists: A combined ERP and motion capture study
2013
Performing a piece of music involves the interplay of several cognitive and motor processes and requires extensive training to achieve a high skill level. However, even professional musicians commit errors occasionally. Previous event-related potential (ERP) studies have investigated the neurophysiological correlates of pitch errors during piano performance, and reported pre-error negativity already occurring approximately 70–100 ms before the error had been committed and audible. It was assumed that this pre-error negativity reflects predictive control processes that compare predicted consequences with actual consequences of one's own actions. However, in previous investigations, correct a…
Silent music reading: Amateur musicians' visual processing and descriptive skill
2013
This article addresses the silent reading of music notation, combining eye-movement measures with a semantic analysis of readers’ verbal descriptions of the notated music. A group of musical novices ( n = 16) and two groups of musical amateurs (less experienced n = 11 and more experienced n = 10) participated in three separate measurement sessions during a nine-month-long university music course designed for future primary-school teachers. In each session they viewed a notated folk song for 30 s and then described what they had seen. Greater musical experience was found to be connected with shorter fixation durations, more linear scanning of the notated music, and more accurate and integra…
Mutational analysis of the RNA-binding domain of the Prunus necrotic ringspot virus (PNRSV) movement protein reveals its requirement for cell-to-cell…
2005
AbstractThe movement protein (MP) of Prunus necrotic ringspot virus (PNRSV) is required for cell-to-cell movement. MP subcellular localization studies using a GFP fusion protein revealed highly punctate structures between neighboring cells, believed to represent plasmodesmata. Deletion of the RNA-binding domain (RBD) of PNRSV MP abolishes the cell-to-cell movement. A mutational analysis on this RBD was performed in order to identify in vivo the features that govern viral transport. Loss of positive charges prevented the cell-to-cell movement even though all mutants showed a similar accumulation level in protoplasts to those observed with the wild-type (wt) MP. Synthetic peptides representin…
Acoustic rhinometry in pre-school children.
1993
Acoustic rhinometry was performed in 35 normal nose-breathing children between 3 and 6 years. The average cross-sectional areas at the nasal valve, at the anterior end of the turbinates, and in the nasopharynx were 0.34 +/- 0.06 cm2, 0.35 +/- 0.08 cm2 and 1.37 +/- 0.48 cm2 respectively. The average minimal cross-sectional area was 0.29 +/- 0.06 cm2. The minimal cross-sectional area was located at the nasal valve in 14 and at the anterior end of nasal turbinates in 21 of the 35 children. As would be expected, the cross-sectional areas at different sites of the nasal cavity increased with increasing age of the children. But, whereas the minimal cross-sectional area increased by 0.024 cm2 per …
La suspensión de la libre circulación de inversiones extranjeras en España por la crisis del COVID-19
2020
La libre circulación de inversiones es uno de los mantras que ha caracterizado la modernidad económica. El principio, sin embargo, se encuentra sometido a creciente prevención, en el marco de una visión crítica hacia la globalización en un mundo en pleno reajuste geoestratégico. Una de las manifestaciones de esta tendencia reciente de empoderamiento del Estado se refleja en la articulación de mecanismos de control de las inversiones foráneas que le permitan evitar que sectores claves de la economía nacional caigan en manos de inversores extranjeros, en muchas ocasiones, controlados por Estados competidores. A diferencia de lo que ocurre con los países de nuestro entorno, España había sido i…
