Mismatch negativity (MMN) in freely-moving rats with several experimental controls.

2014

Mismatch negativity (MMN) is a scalp-recorded electrical potential that occurs in humans in response to an auditory stimulus that defies previously established patterns of regularity. MMN amplitude is reduced in people with schizophrenia. In this study, we aimed to develop a robust and replicable rat model of MMN, as a platform for a more thorough understanding of the neurobiology underlying MMN. One of the major concerns for animal models of MMN is whether the rodent brain is capable of producing a human-like MMN, which is not a consequence of neural adaptation to repetitive stimuli. We therefore tested several methods that have been used to control for adaptation and differential exogenou…

Might as well jump: Sound affects muscle activation in skateboarding

2014

The aim of the study is to reveal the role of sound in action anticipation and performance, and to test whether the level of precision in action planning and execution is related to the level of sensorimotor skills and experience that listeners possess about a specific action. Individuals ranging from 18 to 75 years of age - some of them without any skills in skateboarding and others experts in this sport - were compared in their ability to anticipate and simulate a skateboarding jump by listening to the sound it produces. Only skaters were able to modulate the forces underfoot and to apply muscle synergies that closely resembled the ones that a skater would use if actually jumping on a ska…

REPLACER L'AUDITEUR AU COEUR DE SON METIER: UNE ETUDE EXPLORATOIRE SUR LE MARCHE FRANÇAIS

2012

The auditor's judgment, faces new stakes bound up to the industrialization of the audit process and to the development of the new information and communication technologies. These evolutions, complicate the audit practices and calling into question to the professional judgment exercise. The aim of our research is to contribute, to restore and to re-size the place granted to the professional judgment. To be made we led two studies: a qualitative study realized with a sample consisted of 22 auditors and a documentary study based on the booklet of The Green Paper on Audit Policy. The results show that there is a dialectical relation between the technical dimension and the human dimension of th…

It's Sad but I Like It The Neural Dissociation Between Musical Emotions and Liking in Experts and Laypersons

2016

Emotion-related areas of the brain, such as the medial frontal cortices, amygdala, and striatum, are activated during listening to sad or happy music as well as during listening to pleasurable music. Indeed, in music, like in other arts, sad and happy emotions might co-exist and be distinct from emotions of pleasure or enjoyment. Here we aimed at discerning the neural correlates of sadness or happiness in music as opposed those related to musical enjoyment. We further investigated whether musical expertise modulates the neural activity during affective listening of music. To these aims, 13 musicians and 16 non-musicians brought to the lab their most liked and disliked musical pieces with a …

Reģionālā laikraksta “Auseklis” dienaskārtības un auditorijas dienaskārtības un vajadzību salīdzinājums

2018

Bakalaura darba “Reģionālā laikraksta “Auseklis” dienaskārtības un auditorijas dienaskārtības un vajadzību salīdzinājums”. Mērķis ir noskaidrot, vai reģionālās preses auditorija ir apmierināta ar iegūto informāciju un vai medija dienaskārtība ir atbilstoša lasītāju dienaskārtībai un vajadzībām, kā arī uzzināt ieteikumus no auditorijas pārstāvjiem, kādu informāciju viņi galvenokārt vēlētos saņemt. Darba teorētiskā daļa balstīta uz dienaskārtības, lietojuma un apmierinājuma teorijām, kā arī ieļauta literatūra par vajadzības jēdzienu, lokālo mediju un tā auditorijas skaidrojumu. Pētījumā izmantotas tādas pētnieciskās metodes, kā kvalitatīvā kontentanalīze, aptauja un salīdzinošā analīze. Empīr…

Spoken-Word Segmentation and Dyslexia

2002

We used magnetoencephalography to elucidate the cortical activation associated with the segmentation of spoken words in nonreading-impaired and dyslexic adults. The subjects listened to binaurally presented sentences where the sentence-ending words were either semantically appropriate or inappropriate to the preceding sentence context. Half of the inappropriate final words shared two or three initial phonemes with the highly expected semantically appropriate words. Two temporally and functionally distinct response patterns were detected in the superior temporal lobe. The first response peaked at approximately 100 msec in the supratemporal plane and showed no sensitivity to the semantic appr…

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…

Neural generators of the frequency-following response elicited to stimuli of low and high frequency: A magnetoencephalographic (MEG) study.

2021

The frequency-following response (FFR) to periodic complex sounds has gained recent interest in auditory cognitive neuroscience as it captures with great fidelity the tracking accuracy of the periodic sound features in the ascending auditory system. Seminal studies suggested the FFR as a correlate of subcortical sound encoding, yet recent studies aiming to locate its sources challenged this assumption, demonstrating that FFR receives some contribution from the auditory cortex. Based on frequency-specific phase-locking capabilities along the auditory hierarchy, we hypothesized that FFRs to higher frequencies would receive less cortical contribution than those to lower frequencies, hence supp…

Dynamics of brain activation during learning of syllable-symbol paired associations.

2019

| openaire: EC/H2020/641652/EU//ChildBrain Initial stages of reading acquisition require the learning of letter and speech sound combinations. While the long-term effects of audio-visual learning are rather well studied, relatively little is known about the short-term learning effects at the brain level. Here we examined the cortical dynamics of short-term learning using magnetoencephalography (MEG) and electroencephalography (EEG) in two experiments that respectively addressed active and passive learning of the association between shown symbols and heard syllables. In experiment 1, learning was based on feedback provided after each trial. The learning of the audio-visual associations was c…
