Measures of auditory brain responses in children / adolescents.

Abstract

Different studies have performed analysis at the electrode level comparing different aspects of the EEG signals. Including auditory stimulation and population with reading difficulties such as dyslexia. These studies showed interesting results proving that EEG recordings with auditory stimulation may show differences between the populations under study. Studying at the source level the underlying differences showed at electrode level might provide even more information about the differences between groups with reading difficulties and normal developing readers across different ages.

Towards a comfortable cocktail party for bimodal listeners

Benjamin Dieudonné

Research Seminar in framework of doctoral education

When?

Thursday, 14 December 2017, 17:00-18:00

Abstract

An increasingly common solution to severe hearing loss is bimodal stimulation: a cochlear implant in one ear and a hearing aid in the other. Although more and more companies are offering so-called bimodal solutions, the two devices are not designed to work together. This leads to poor transmission of binaural cues, resulting in major difficulties with sound localization and speech understanding in noisy environments. We will present the difficulties that bimodal listeners experience due to poor perception of binaural cues, and suggest some possible solutions to overcome these difficulties. One novel sound processing strategy that we recently developed, head shadow enhancement, did yield some promising results.

Structural connectivity analysis algorithms for young children's brain

Abstract

In the research field of developmental neuroscience, an increasing number of studies investigates early childhood as this is the period when drastic structural changes occur in the brain. With the advent of child-friendly scanning protocols, studies based on Magnetic Resonance Imaging (MRI) have started to increase, with the advantage of providing in vivo and non-invasive high-resolution images of the brain. However, it was demonstrated that applying standard MRI software tools on young children data provides inaccurate and biased results, which can lead to erroneous interpretation in the analysis. The aim of this project is to develop and validate a tool for the structural connectivity analysis of young children’s brain. Improved modelling of brain connectivity attempts to better represent the links between brain structures, with accurate segmentation of anatomical brain regions and white matter connections representation. To do so, processing methods based on anatomical and diffusion MRI are adjusted to the young children’s brain. IOptimal pre-processing such as non-linear registration and artefact correction are applied to deal with issue inherent to pediatric data (head motion and anatomical disparity). Age-specific atlases are used (or constructed, if not available) in order to summarise the brain anatomy specific to each age group. Multi-atlas based methods are used in order to improve the segmentation accuracy of multiple labelling of brain sub-regions. Finally, longitudinal design is also included so changes in both micro- and macrostructure can be measured during brain development. Studies are conducted to evaluate the impact of these adapted processing methods applied for brain structural connectivity analysis in young children’s brain in typical and atypical development.​

Optical imaging for hearing research: possibilities and possible pitfalls

 Dr. Hamish Innes-Brown

Bionics Institute, Melbourne, Australia

Abstract

Functional near-infrared spectroscopy is a brain imaging technique that holds great promise for hearing research. It measures regionally-specific changes in the concentrations of oxygenated and deoxygenated haemoglobin in the superficial layers of cortex that are due to neural activity. Importantly for hearing research, it is non-invasive, silent, can be used in a variety of seating positions, and can be used with implanted devices such as cochlear implants. In this talk I will describe our first few years using this technology, some of the problems we have come across, and the potential we see for future uses.

Neural entrainment to the speech envelope in cochlear implant users

Ben Somers

Research Seminar in framework of doctoral education

Abstract

The temporal envelope of speech is encoded in the oscillating patterns of the listener’s brain. Recent studies with normal hearing participants have shown that this neural representation of the envelope can be decoded from EEG measurements, and that it is related to speech intelligibility. Obtaining a measure for neural entrainment to the speech envelope in response to electrical stimulation with a cochlear implant poses additional challenges, as the electrical artifacts are continuously present and obscure the EEG. In the presented study, the successful decoding of the speech envelope from EEG measured in cochlear implant users is demonstrated for the first time.
