OnabotulinumtoxinA Modulates Visual Cortical Excitability in Chronic Migraine: Effects of 12-Week Treatment
2022
Chronic migraine is a burdensome disease presenting with episodic pain and several symptoms that may persist even among headache attacks. Multisensory integration is modified in migraine, as assessed by the level of the perception of sound-induced flash illusions, a simple paradigm reflecting changes in cortical excitability which reveals to be altered in migraineurs. OnabotulinumtoxinA is an effective preventive therapy for chronic migraineurs, reducing peripheral and central sensitization, and may influence cortical excitability. Patients affected by chronic migraine who started onabotulinumtoxinA preventive therapy were included. Clinical effects (headache diaries and migraine related qu…

Visual cues improve students’ understanding of divergence and curl: Evidence from eye movements during reading and problem solving
2019
The coordination of multiple external representations is important for learning, but yet a difficult task for students, requiring instructional support. The subject in this study covers a typical relation in physics between abstract mathematical equations (definitions of divergence and curl) and a visual representation (vector field plot). To support the connection across both representations, two instructions with written explanations, equations, and visual representations (differing only in the presence of visual cues) were designed and their impact on students’ performance was tested. We captured students’ eye movements while they processed the written instruction and solved subsequent c…
Encoding specificity instead of online integration of real-world spatial regularities for objects in working memory
2022
Most objects show high degrees of spatial regularity (e.g. beach umbrellas appear above, not under, beach chairs). The spatial regularities of real-world objects benefit visual working memory (VWM), but the mechanisms behind this spatial regularity effect remain unclear. The "encoding specificity" hypothesis suggests that spatial regularity will enhance the visual encoding process but will not facilitate the integration of information online during VWM maintenance. The "perception-alike" hypothesis suggests that spatial regularity will function in both visual encoding and online integration during VWM maintenance. We investigated whether VWM integrates sequentially presented real-world obje…
Aistikanavapohjaisesti eriytetyn verkko-oppimisympäristön analyysi
2017
Tutkimuksessa analysoidaan verkko-oppimisympäristön oppimateriaalin eriyttämistä aistikanavapohjaisesti. Oppimateriaalin eriyttämiseen käytetään VARK-miellejärjestelmämallia, joka pyrkii tukemaan oppilaan oppimismieltymyksiä luokittelemalla kyselyn avulla oppilaat visuaalisen, auditiivisen, lukija–kirjoittaja- ja kinesteettisen aistipreferenssin mukaan ja tarjoamalla luokittelun perusteella heille erilaisia oppimisstrategioita. Työssä tutkitaan, miten VARK-miellejärjestelmä soveltuu yläkoululaisten historian verkko-oppimateriaalin eriyttämisen perustaksi oppimistulosten ja oppimiskokemusten näkökulmasta. Tutkimusta varten luotiin verkko-oppimisympäristö, johon koottiin yhden oppitunnin aika…
Tout savoir sur le treat and extend : organisation et optimisation. Les Cahiers d'Ophtalmologie
2019
La dégénérescence maculaire liée à l’âge (DMLA) est actuellement la première cause de handicap visuel dans les pays développés chez les plus de 50 ans. Elle touche en effet environ 8% de la population française et plus de 25% des plus de 75 ans. La constatation d’une insuffisance de traitement lors d’un régime « réactif » a poussé les cliniciens à proposer d’autres types de régimes. Le « Treat and Extend » (T&E) est né de la volonté d’adapter les intervalles de retraitement des patients pour une prise en charge plus personnalisée.
Preferències sensorials i ús autopercebut d’estratègies en l’aprenentatge de les ciències dels estudiants de secundària: anàlisis i proposta instrucc…
2019
Las diferencias individuales de los estudiantes de secundaria y los factores con influencia en el aprendizaje de las ciencias fueron el tema principal de esta Tesis. Esta investigación se centró en la descripción y el análisis de las preferencias sensoriales del estudiante y la conexión entre ellos y los recursos instruccionales utilizados en las secuencias didácticas usadas en el aprendizaje de las ciencias en secundaria. Existe una posible explicación sobre el beneficio de los estudiantes mediante el uso de ciertos materiales de aprendizaje. El aprendizaje multimedia definido por Mayer (2005) establecía que el cerebro humano asigna diferentes recursos cognitivos para la recepción de difer…
Seeing Gravity: Gait Adaptations to Visual and Physical Inclines – A Virtual Reality Study
2020
Using advanced virtual reality technology, we demonstrate that exposure to virtual inclinations visually simulating inclined walking induces gait modulations in a manner consistent with expected gravitational forces (i.e., acting upon a free body), suggesting vision-based perception of gravity. The force of gravity critically impacts the regulation of our movements. However, how humans perceive and incorporate gravity into locomotion is not well understood. In this study, we introduce a novel paradigm for exposing humans to incongruent sensory information under conditions constrained by distinct gravitational effects, facilitating analysis of the consistency of human locomotion with expecte…
