Proprioceptive response strength in the primary sensorimotor cortex is invariant to the range of finger movement

2023

Available online 13 February 2023 Proprioception is the sense of body position and movement that relies on afference from the proprioceptors in muscles and joints. Proprioceptive responses in the primary sensorimotor (SM1) cortex can be elicited by stim- ulating the proprioceptors using evoked (passive) limb movements. In magnetoencephalography (MEG), propri- oceptive processing can be quantified by recording the movement evoked fields (MEFs) and movement-induced beta power modulations or by computing corticokinematic coherence (CKC) between the limb kinematics and cortical activity. We examined whether cortical proprioceptive processing quantified with MEF peak strength, relative beta supp…

Training practices of Filipino athletes during the early covid-19 lockdown

2022

The imposition of COVID-19 lockdown restricted the daily activities of many people, including athletes. This study investigated the training practices of athletes in the Philippines during the first COVID-19 lockdown. A total of 442 athletes answered an online survey (May-July 2020), with questions pertaining to training practices, such as training frequency and duration. Data were analyzed according to: athlete classification (world-class, international, national, state, or recreational), sport category (individual or team), and sex (male or female). During lockdown, significant reductions in training frequency (except recreational, i.e., lower pre-lockdown training) and duration were obse…

Corticokinematic coherence is stronger to regular than irregular proprioceptive stimulation of the hand

2021

Funding Information: This study was supported by the Academy of Finland “Brain changes across the life-span” profiling funding to University of Jyva€skyla€. H. Piitulainen was supported by Academy of Finland (Grants 296240, 326988, 307250, and 327288) and Jane and Aatos Erkko Foundation. Publisher Copyright: © 2021 the American Physiological Society. Proprioceptive afference can be investigated using corticokinematic coherence (CKC), which indicates coupling between limb kinematics and cortical activity. CKC has been quantified using proprioceptive stimulation (movement actuators) with fixed interstimulus interval (ISI). However, it is unclear how regularity of the stimulus sequence (jitter…

Edukacja techniczna wsparciem rozwoju małej motoryki uczniów w młodszym wieku szkolnym

2018

Sprawność manualna dziecka rozwija się w toku różnorodnych ćwiczeń i zadań ruchowych usprawniających pracę mięśni drobnych oraz koordynację oka i ręki. Od tego, jaki poziom osiągnie dziecko w tym zakresie, zależy, między innymi, przebieg procesu nauki pisania oraz wykonania wszelkich prac manualnych, jednym z zadań edukacji technicznej w przedszkolu, a także w kształceniu wczesnoszkolnym jest rozwijanie motoryki niezbędnej do prawidłowego funkcjonowania dziecka w szkole i w życiu. Proces dochodzenia do biegłości w wykonywaniu precyzyjnych ruchów jest długotrwały i uwarunkowany zarówno cechami indywidualnymi, jak też przebiegiem i intensywnością ćwiczeń w tym zakresie. Przedmiotem poniższego…

Lo sviluppo dell’intelligenza linguistica e della competenza comunicativa degli studenti universitari. Un esperimento Brain-Based in Dad

2021

Il contributo presenta l’utilizzo di un approccio di tipo Brainbased allo sviluppo dell’intelligenza linguistica e della correlata competenza linguistico-comunicativa, che ha permesso la sperimentazione di una batteria di attività di Brain Gym (Dennison & Dennison, 2008) nel contesto didattico universitario durante il periodo di Didattica a Distanza (DAD) imposta dalla pandemia da Covid-19. La DAD ha comportato una drastica limitazione di alcuni elementi considerati fondanti per lo sviluppo delle competenze linguistiche, espressive e comunicative quali la corporeità, il controllo visuo-acustico, i tempi d’attenzione, la gestualità, il contatto. Nella sua fase iniziale, la ricerca condot…

A SUMOylation-defective MITF germline mutation predisposes to melanoma and renal carcinoma

2011

International audience; So far, no common environmental and/or phenotypic factor has been associated with melanoma and renal cell carcinoma (RCC). The known risk factors for melanoma include sun exposure, pigmentation and nevus phenotypes; risk factors associated with RCC include smoking, obesity and hypertension. A recent study of coexisting melanoma and RCC in the same patients supports a genetic predisposition underlying the association between these two cancers. The microphthalmia-associated transcription factor (MITF) has been proposed to act as a melanoma oncogene; it also stimulates the transcription of hypoxia inducible factor (HIF1A), the pathway of which is targeted by kidney canc…

Spatial Cognition 2020/1: Book of abstracts : August 2-4, 2021, University of Latvia

2021

Spatial Cognition is concerned with the acquisition, development, representation, organization, and use of knowledge about spatial objects in real, virtual or hybrid environments and processed by human or artificial agents. Spatial Cognition includes research from different fields insofar as they are concerned with cognitive agents and space, such as cognitive and developmental psychology, linguistics, computer science, geography, cartography, philosophy, neuroscience, and education. Research issues in the field range from the investigation of human spatial cognition to mobile robot navigation, including topics such as wayfinding, spatial planning, spatial learning, internal and external re…

Investigating Relationships Between Music, Emotions, Personality, and Music-Induced Movement

2013

Listening to music makes us to move in various ways. The characteristics of these movements can be affected by several aspects, such as individual factors, musical features, or the emotional content of the music. In a study in which we presented 60 individuals with 30 musical stimuli representing different genres of popular music and recorded their movement with an optical motion capture system, we found significant correlations 1) between musical characteristics and the exhibited movement, 2) between the perceived emotional content of the music and the movement, and 3) between personality traits of the dancers and the movement. However, such separate analyses are incapable of investigating…

Constant Power Model in Arm Rotation—A New Approach to Hill’s Equation

2014

The purpose of this study was to further develop the constant power model of a previous study and to provide the final solution of Hill’s force-velocity equation. Forearm and whole arm rotations of three different subjects were performed downwards (elbow and shoulder extension) and upwards (elbow and shoulder flexion) with maximum velocity. These arm rotations were recorded with a special camera system and the theoretically derived model of constant maximum power was fitted to the experimentally measured data. The moment of inertia of the arm sectors was calculated using immersion technique for determining accurate values of friction coefficients of elbow and whole arm rotations. The experi…
