At the cortical level, the central auditory neural system (CANS) includes primary and secondary areas. So far, much research has focused on recording fronto-central auditory evoked potentials/responses (P1-N1-P2), originating mainly from the primary auditory areas, to explore the neural processing in the auditory cortex. However, less is known abou...

Purpose Magnetic resonance imaging (MRI), electric compound action potential (eCAP), and electric auditory brainstem response (eABR) are among the routine assessments performed before and/or after cochlear implantation. The objective of this review was to systematically summarize and critically appraise existing evidence of the prognostic value of...

Objectives Current evidence supports the benefits of cochlear implants (CIs) in children with hearing loss, including those with auditory neuropathy spectrum disorder (ANSD). However, there is limited evidence regarding factors that hold predictive value for intervention outcomes. Design This retrospective case-control study consisted of 66 childr...

Background and Aim: Sensorineural Hearing Loss (SNHL) reduces audibility and causes distortion, which result in difficulty with speech processing, especially in noisy environments. One of the new speech-in-noise tests is the Words-in-Noise (WIN) test. This study aimed to further investigate the Signal-to-Noise Ratio 50% (SNR-50) in subjects with mi...

Introduction The occurrence of mild traumatic brain injury(mTBI) is estimated at 0,2-0,3% cases annually. Following a mTBI, some children experience persistent symptoms, and functional connectivity(FC) changes may be implicated. However, characteristics of FC have not been widely described in this population. This scoping review aimed to identify a...

Purpose The objective of this overview of systematic reviews (SRs; umbrella review) was to systematically summarize and critically appraise current evidence of cochlear implant (CI) outcomes in children with auditory neuropathy spectrum disorder (ANSD). Method This study was guided by the Preferred Reporting Items for Systematic Reviews and Meta-A...

Background: (Central) auditory processing disorders, (C)APDs are clinically identified using behavioral tests. However, changes in attention and motivation may easily affect true identification. Although auditory electrophysiological tests, such as Auditory Brainstem Responses (ABR), are independent of most confounding cognitive factors, there is...

Background: Auditory processing disorders (APD) may be one of the problems experienced by children with listening difficulties (LiD). The combination of auditory behavioural and electrophysiological tests could help to provide a better understanding of the abilities/disabilities of children with LiD. The current study aimed to quantify the auditor...

Whereas growing evidence supports the advantages of bilingualism for brain structure and function, no study has shown multilingual-related neuroplasticity in response to speech stimuli at the subcortical level. To investigate the impact of multilingualism on subcortical auditory processing, the speech auditory evoked response (speech-ABR) was recor...

Purpose The long latency auditory evoked responses (LLAERs), originating in the auditory cortex, are often considered a biomarker for maturity in the central auditory system and may therefore be useful in the evaluation of children with central auditory processing disorder (CAPD). However, the characteristics of the LLAERs elicited in this populati...

Purpose: The main purpose of this retrospective study was to identify auditory dysfunctions related to traumatic brain injury (TBI) in individuals evaluated in an Audiology clinic. Method: Peripheral and central auditory evaluations were performed from March 2014 to June 2018 in 26 patients (14 males) with TBI. The age of the participants ranged fr...

Background and Aim: Hearing loss in children leads to speech and language delays, low academic achievement, literacy delays, and psychosocial difficulties. Screening instrument for targeting educational risk (SIFTER) is one of the questionnaires used for evaluation of students’ performance in schools. The current study aims to develop Persian versi...

The uOttawa Piano Pedagogy Research Laboratory, in collaboration with researchers from uOttawa Audiology and the ENT and Otolaryngology clinic at the Children’s Hospital of Eastern Ontario (CHEO), has been running a research program to investigate the abilities of cochlear implant (CI) recipients in learning and performing music, and the effects of...

Auditory temporal resolution is critical for the perception of speech. It is often studied using gap detection methods in which a silent period (or “gap”) is inserted in a long duration auditory stimulus. When the gap is inserted in a frequently occurring standard stimulus, it elicits a negative-going event-related potential, called the deviant-rel...

Typical development and maturation of the auditory system, at both the peripheral and central levels, is essential for the acquisition of speech, language, and auditory skills. The peripheral system generally encodes three basic parameters associated with auditory stimuli-time, frequency, and intensity. These acoustic cues are subsequently processe...

L'objectif principal de cette étude était d'évaluer l'effet de l'enrichissement sensoriel, tel que le bilinguisme, sur le traitement auditif sous-cortical, dans deux types de conditions d'écoute : dans le silence et dans le bruit. Plus spécifiquement, le but de cette étude était d'identifier des marqueurs biologiques neuronaux, au niveau du tronc c...

Cette étude a examiné l'impact de cours de chant sur le traitement auditif sous-cortical chez les enfants atteints d'un trouble du traitement auditif (TTA). Onze enfants de 7 à 11 ans ont participé à cette étude. Les potentiels évoqués auditifs du tronc cérébral (PEATC) ont été enregistrées en utilisant un stimulus auditif non verbal (clic) et un s...

The Auditory Brainstem Response (ABR) can be used to measure the early temporal activity of the auditory system. A gapin-noise ABR has been developed to measure the electrophysiological response to auditory stimulation without attending to the task. In the present study, young adults passively listened to stimuli of various gap widths in separate s...

The insertion of a silent period (or gap) in a frequently occurring standard stimulus elicits a negative-going event-related potential (ERP), called the Deviant-Related Negativity (DRN). This is often studied using a single-deviant paradigm. To study the effects of gaps with multiple durations, a different sequence would be required for each gap. A...

This study examined the hearing sensitivity of university music students (N = 53) and a control group (N = 54) between the ages of 17 and 31. The two groups were compared for differences in hearing threshold levels, incidence of hearing loss described by pure-tone average levels, and incidences of notches at 3, 4 or 6 kHz. Survey data were also use...

Motor imagery-based brain computer interfacing (MI-BCI) as a neuro-rehabilitation tool aims at facilitating motor improvement using mental practice. However, the effectiveness of MI-BCI in producing clinically meaningful functional outcome is debated. Aside from computational shortcomings, a main limiting obstacle seems to be the substantial repres...

The auditory brainstem response (ABR) in tinnitus subjects has been extensively investigated over the last decade with the hopes of finding possible abnormalities related to the pathology. Despite this effort, the use of the ABR for tinnitus diagnosis or as an outcome measure is under debate. The present study reviewed published literature on ABR a...

This multiple single-subject research study explores how deaf children with cochlear implants (CIs) can appreciate and engage in piano lessons. Three CI children and 2 normalhearing children received 6 months of formal individual piano lessons where aural modeling was the main teaching method. Engagement was measured by a daily practice logbook ind...

The main objective of the present study was to identify markers of neural deficits in children with central auditory processing disorder (CAPD) by measuring latency and amplitude of the auditory cortical responses and mismatch negativity (MMN) responses. Passive oddball paradigms were used with nonverbal and verbal stimuli to record cortical audito...

The attached poster is a study comparing two MMN paradigms, the optimal and the oddball. Many authors assume that tinnitus may ”fill in” the gap, maksing it less perceptible. If this is the case, the MMN to the gap stimulus should be reduced in amplitude in people with tinnitus. The method must however first be validated in normal hearing controls....

Attempts to develop objective measures of tinnitus have been previously unsuccessful due to factors that accompany tinnitus instead of characteristics specific to tinnitus alone (Liu and Chen, 2012). However we believe combining the ABR with a novel gapped and frequency-specific stimulus may eliminate the contamination of other factors and provide...

Purpose The objective was to assess auditory sequential organization (ASO) ability in children with and without hearing loss. Method Forty children 9 to 12 years old participated in the study: 12 with sensory hearing loss (HL), 12 with central auditory processing disorder (CAPD), and 16 with normal hearing. They performed an ASO task in which they...

Objective: The aim of the study was to investigate the neurophysiological responses in children with hearing loss. Methods: Cortical auditory evoked potentials and Mismatch Negativity (MMN) Responses were recorded in 40 children, 9-12 years old: 12 with hearing loss, 12 with central auditory processing disorder (CAPD) and 16 with normal hearing....

Objective. This study examined the patterns of neural activity in the central auditory system in children with hearing loss. Methods. Cortical potentials and mismatch responses (MMRs) were recorded from ten children aged between 9 and 10 years: five with hearing loss and five with normal hearing in passive oddball paradigms using verbal and nonverb...

The main objective of this study was to assess the influence of peripheral hearing loss (abnormal encoding of the auditory system) on auditory information processing. We examine the ability of children with and without hearing loss to correctly reproduce sequence blocks of acoustic stimuli that vary in type, number, and temporal ordering. Twenty-si...
