Article
Full-text available
A consistent limitation when designing event-related potential paradigms and interpreting results is a lack of consideration of the multivariate factors that affect their elicitation and detection in behaviorally unresponsive individuals. This paper provides a retrospective commentary on three factors that influence the presence and morphology of l...
Article
Full-text available
This cross-linguistic study investigates the impact of spelling errors on reading behavior in five languages (Chinese, English, Finnish, Greek, and Hebrew). Learning theories predict that correct and incorrect spelling alternatives (e.g., tomorrow and tommorrow) provide competing cues to the sound and meaning of a word: the closer the alternatives...
Article

Objectives: The N2b is an event-related potential (ERP) component thought to index higher-order executive function. While the impact of concussion on executive functioning is frequently discussed in the literature, limited research has been done on the role of N2b in evaluating executive functioning in patients with concussion. The aims of this rev...
Article
Full-text available
Objective The present study sought to determine: 1) whether concussed adolescents exhibited deficits in neurocognitive functioning as reflected by neurophysiological alterations; 2) if neurophysiological alterations could be linked to supplementary data such as the number of previous concussions and days since injury; and 3) if deficits in psycholo...
Article
Full-text available
The current literature presents a discordant view of mild traumatic brain injury and its effects on the human brain. This dissonance has often been attributed to heterogeneities in study populations, etiology, acuteness, experimental paradigms, and/or testing modalities. To investigate the progression of mild traumatic brain injury in the human bra...
Article
Full-text available
Concussion has been shown to leave the afflicted with significant cognitive and neurobehavioural deficits. The persistence of these deficits and their link to neurophysiological indices of cognition, as measured by event-related potentials (ERP) using electroencephalography (EEG), remains restricted to population level analyses that limit their uti...
Article
There has been increased effort to understand the neurophysiological effects of concussion aimed to move diagnosis and identification beyond current subjective behavioural assessments that suffer from poor sensitivity. Recent evidence suggests that event-related potentials (ERPs) measured with electroencephalography (EEG) are persistent neurophysio...
Article
Current models of spoken word recognition have been predominantly based on studies of Indo-European languages. As a result, less is known about the recognition processes involved in the perception of tonal languages (e.g., Mandarin Chinese), and the role of lexical tone in speech perception. One view is that words in tonal languages are processed p...

Introduction: Coma is a deep state of unconsciousness that can be caused by a variety of clinical conditions. Traditional tests for coma outcome prediction are based mainly on a set of clinical observations. Recently, certain event-related potentials (ERPs), which are transient electroencephalogram (EEG) responses to auditory, visual or tactile sti...
Article
Objective: Recent studies demonstrate that sports-related concussions can have negative consequences on long-term brain health. The goal of the present study was to determine whether retired Canadian Football League (CFL) athletes with a history of concussions exhibit alterations in neurocognitive functioning, along with changes in physical, socia...

It has been demonstrated repeatedly that mild traumatic brain injury (mTBI) (concussion) results in neurological deficits (Dupuis et al, 2000; De Beaumont et al, 2007; Covassin et al, 2008). Moreover, individuals diagnosed with a concussion often suffer from prolonged physical, cognitive, and emotional/behavioral symptoms referred to as post-concus...

Abstract: Introduction/Background: Event Related Potential (ERP) analysis of Electroencephalography (EEG) data has been widely used in research on language, cognition, and pathology. The high dimensionality of a typical EEG/ERP dataset makes it a time-consuming prospect to properly analyze, explore, and validate knowledge without a particular restr...
Article
Full-text available
Up to 40% of individuals with unresponsive wakefulness syndrome (UWS) actually might be conscious. Recent attempts to detect covert consciousness in behaviorally unresponsive patients via neurophysiological patterns are limited by the need to compare data from brain-injured patients to healthy controls. In this report, we pilot an alternative withi...

We collected EEG data from both Health Controls (HC) and Concussed Adolescents (CA) and found significantly delayed Mismatch Negativity (MMN) latencies to frequency and intensity “deviant” tones in the CA group, while no significant amplitude differences to any of the ”deviant” stimuli (intensity, frequency and duration) were found between the grou...

Event Related Potential (ERP) analysis of Electroencephalography (EEG) data has been widely used in research on language, cognition, and pathology. The high dimensionality (time x channel x condition) of a typical EEG/ERP dataset makes it a time-consuming prospect to properly analyze, explore, and validate knowledge without a particular restricted...
Article
Event-related potentials (ERPs) may provide a non-invasive index of brain function for a range of clinical applications. However, as a lab-based technique, ERPs are limited by technical challenges that prevent full integration into clinical settings. To translate ERP capabilities from the lab to clinical applications, we have developed methods like...
Article
Full-text available
Event-related potentials (ERPs) are tiny electrical brain responses in the human electroencephalogram (EEG) that are typically not detectable until they are isolated by a process of signal averaging. Owing to the extremely small size of ERP components (ranging from less than 1 μV to tens of μV), compared to background brain rhythms, statistical ana...

Project
The goal of the project is to use a range of neurophysiological measures to assess cognitive function in patients who are impossible or difficult to assess using traditional behaviourally based measures of cognitive function.
