Efficiency of Multisensoric Therapy in Autism Spectrum Disorder Patients

2018

Abstract The aim of this study was to investigate the role of various treatment methods for children with autistic spectrum disorders (ASD). The prospective study was conducted in 2013–2015 at the Children’s University Hospital and Social Pediatric Centre of the University of Latvia. The data analysis included 72 children (2 to 5 year old) with ASD, of whom 38 had infantile autism, 16 had atypical autism, and 18 had other diffuse developmental disorder). 86.1% patients received therapy. The most common treatment was by Montessori method and special pedagogue. Other treatments were dance-movement therapy, animal, sand and one patient received spa treatments. Univariate OR analysis showed tha…

Testing cognition and rehabilitation in unilateral neglect with wedge prism adaptation: multiple interplays between sensorimotor adaptation and spati…

2014

Spatial neglect is a neurological condition characterised by deficits for perceiving, attending, representing, and/or performing actions within their left-sided space, responsible for numerous debilitating effects in everyday life, for poor functional recovery, and for decreased ability to benefit from treatment. Exposure to a right lateral displacement of the visual field (induced by a simple target-pointing task with base-left wedge prisms) is known to directionally bias visuomotor coordination and can be compensated by both sensorimotor adaptation and cognitive processes. Sensorimotor adaptation gives rise to after-effects whose duration is amplified in neglect patients and has been repe…

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 …

TickTacking – Drawing trajectories with two buttons and rhythm

2023

The navigation of two-dimensional spaces by rhythmic patterns on two buttons is investigated. It is shown how direction and speed of a moving object can be controlled with discrete commands consisting of duplets or triplets of taps, whose rate is proportional to one of two orthogonal velocity components. The imparted commands generate polyrhythms and polytempi that can be used to monitor the object movement. Tacking back and forth must be used to make progress along certain directions, similarly to sailing a boat upwind. The proposed rhythmic navigation technique is tested with a target-following task, using a boat-racing trace as the target. The interface is minimal and symmetric, and can …

To “Sketch-a-Scratch”

2015

A surface can be harsh and raspy, or smooth and silky, and everything in between. We are used to sense these features with our fingertips as well as with our eyes and ears: the exploration of a surface is a multisensory experience. Tools, too, are often employed in the interaction with surfaces, since they augment our manipulation capabilities. “Sketch-a-Scratch” is a tool for the multisensory exploration and sketching of surface textures. The user’s actions drive a physical sound model of real materials’ response to interactions such as scraping, rubbing or rolling. Moreover, different input signals can be converted into 2D visual surface profiles, thus enabling to experience them visually…

Effect of Rotating Auditory Scene on Postural Control in Normal Subjects, Patients With Bilateral Vestibulopathy, Unilateral, or Bilateral Cochlear I…

2018

International audience; Objective: The aim of this study was to investigate the impact of a rotating sound stimulation on the postural performances in normal subjects, patients with bilateral vestibulopathy (BVP), unilateral (UCI), and bilateral (BCD cochlear implantees.Materials and Methods: Sixty-nine adults were included (32 women and 37 men) in a multicenter prospective study. The group included 37 healthy subjects, 10 BVP, 15 UCI, and 7 BCI patients. The average of age was 47 +/- 2.0 (range: 23-82). In addition to a complete audiovestibular work up, a dynamic posturography (Multitest Framiral, Grasse) was conducted in silence and with a rotating cocktail party sound delivered by headph…

Impairment of Temporal Binding Window in Migraine Patients

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. …

L'intégration multisensorielle comme stratégie pour compenser la réduction en sodium et matière grasse dans les aliments

2015

In recent years;health authorities worldwide advise for a reduction of salt and fat in daily food consumption. However;foods with reduced salt and fat content are often not appreciated by consumers;Therefore;the formulation of low-salt-fat foods that maintain acceptability is a major concern in food research. In this thesis;the multi-sensory integration and release kinetics of flavor compounds were explored as strategies to compensate for salt and fat reduction in cheese products (model cheeses and real cheeses). The objective was to better understand the mechanisms leading to aroma and salt release during mastication and to evaluate how the matrix composition and structure influence salt a…
