O047. The sound-induced flash illusions reveal visual cortex hyperexcitability in cluster headache
2015
Objectives Pathophysiology of cluster headache (CH) is not wellknown. Although posterior hypothalamus has been suggested to play a pivotal role, evidence exists of a more diffuse involvement of the central nervous system including brainstem and cerebral cortex. In this regard, we recently observed increased motor cortical excitability in episodic CH patients both outside and inside bout [1]. The sound-induced flash illusions (SIFI) represent an example of multisensory integration, and provide a tool to indirectly explore the excitability state of the visual cortex [2]. SIFI are classified as “fission” and “fusion” illusions. When one visual stimulus (flash) is accompanied by two or more aud…

Deep Talk: A Dialogic Instruction Method for Enhancing the Sense of Belonging
2022
In this study, we investigate Deep Talk, which is a method used in the context of early years education in Finland. The method is based on multisensory storytelling and clear phases. The method has received positive feedback from educators and children, but no prior research has been conducted on it. This data aims to determine the significant elements of the method for the individual child and the children in a group. The data consisted of 25 narrations of educators who participated in Deep Talk training and had been serving as Deep Talk instructors. The data were analyzed using a data- and theory-driven qualitative content analysis through the dialogical process of the research team. The …
"Having a drink in a bar": An immersive approach to explore the effects of context on drink choice
2013
UT: 000315557500004; International audience; This paper aims to evaluate the effect of context on food choices. Two studies are presented to test the potential of an immersive approach to help understanding contextual influences on drink choices. To generate contextual effects, two bar-like environments based on the idea of "having a drink in a bar" were created: one with wood furniture and one with blue furniture. In both immersive bars, clips with visual and music stimuli were projected on a wall to change the overall warmth of the ambience. In the first study, five different clips were projected. Participants in the immersive bars had to choose a drink within a large range of drinks for …
Maternal odor selectively enhances the categorization of face(like) stimuli in the 4 month-old infant brain
2020
Présentation Poster; International audience; In the 4-month-old infant brain, the visual categorization of natural face images is enhanced by concomitant maternal odor (Leleu et al., 2019), providing support for the early perception of congruent associations between co-occurring inputs from multiple senses. Here, we further explore whether this maternal odor effect is selective to faces or if it can be explained by a more general influence of salient odor cues on the perception of any visual object category. In Experiment 1, scalp electroencephalogram was recorded during a fast periodic visual stimulation (FPVS-EEG) while 4-month-old infants were exposed to the maternal vs. a control odor. …
Audiovisual processing of Chinese characters elicits suppression and congruency effects in MEG
2019
Learning to associate written letters/characters with speech sounds is crucial for reading acquisition. Most previous studies have focused on audiovisual integration in alphabetic languages. Less is known about logographic languages such as Chinese characters, which map onto mostly syllable-based morphemes in the spoken language. Here we investigated how long-term exposure to native language affects the underlying neural mechanisms of audiovisual integration in a logographic language using magnetoencephalography (MEG). MEG sensor and source data from 12 adult native Chinese speakers and a control group of 13 adult Finnish speakers were analyzed for audiovisual suppression (bimodal responses…
Neurobiological foundations of multisensory processing integration in people with autism spectrum disorders: The role of the medial prefrontal cortex
2014
This review aims to relate the sensory processing problems in people with Autism spectrum disorders (ASD), especially Multisensory interaction (MSI), to the role of the medial prefrontal cortex (mPFC) by exploring neuroanatomical findings; brain connectivity and Default Network (DN); global or locally directed attention; and temporal multisensory binding. The mPFC is part of the brain’s DN, which is deactivated when attention is focused on a particular task and activated on rest when spontaneous cognition emerges. In those with ASD, it is hypoactive and the higher the social impairment the greater the atypical activity. With an immature DN, cross-modal integration is impaired, resulting in …

Multisensorā pieeja bieži sastopamo vārdu atpazīšanas prasmju attīstībai angļu valodā no 5 līdz 6 gadu veciem bērniem
2017
Lasīšana ir viena no būtiskākajām prasmēm, ko skolēni apgūst sākumskolā. Daudziem skolēniem bieži sastopamie vārdi angļu valodā sagādā grūtības, jo tie nepakļaujas zināmajām lasīšanas stratēģijām. Turklāt bieži sastopamie vārdi parādās lielos daudzumos lasīšanas tekstos. Diploma darba autore ir novērojusi, ka ir bērni no 5 līdz 6 gadu vecumam, kuriem grūtības sagādā bieži sastopamus vārdus atpazīšana, tādēļ nav augsts lasīšanas ātrums un izpratne par tekstu. Kā pētījumu metodi autore ir izvēlējusies gadījuma pētījumu, lai izpētītu, kā multisensorā pieeja var palīdzēt 5 līdz 6 gadu veciem skolēniem atpazīt bieži sastopamos vārdus. Pētījums tika veikts 2016.gadā no 17.oktobra līdz 9.decembrim…
Multisensorās stratēģijas skolēnu ar speciālajām vajadzībām iesaistīšanai angļu valodas stundās pamatskolā
2015
Skolotāja pieredzes mapes autore ir angļu valodas skolotāja un speciālais pedagogs vidusskolā. Skolēnu ar speciālajām vajadzībām iekļaušana vispārizglītojošajā skolā ir izraisījusi skolotāju diskusijas par to, kā sekmēt visu skolēnu iesaistīšanos vienas stundas laikā, ņemot vērā, ka viņu spējas un vajadzības ir tik dažādas. Autore ir mēģinājusi atrast visefektīvāko veidu darbā ar skolēniem ar speciālajām vajadzībām; kā risinājums ir rasts multisensoro stratēģiju izmantošana. Lai dalītos profesionālajā pieredzē, kā noslēguma darba forma tika izvēlēta skolotāja pieredzes mape. Darba mērķis ir noskaidrot, kuras multisensorās stratēģijas sekmē skolēnu ar speciālajām vajadzībām iesaistīšanos ang…
