Electrophysiological evidence for the integral nature of tone in Mandarin spoken word recognition

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 …

From Group-Level Statistics to Single-Subject Prediction: Machine Learning Detection of Concussion in Retired Athletes

There has been increased effort to understand the neurophysiological effects of concussion aimed to move diagnosis and identification beyond current subjective behavioral assessments that suffer from poor sensitivity. Recent evidence suggests that …

Neurophysiological Correlates of Concussion: Deep Learning for Clinical Assessment

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 ERPs (ERP) using EEG (EEG), remains …

Correlation of ERP and behavioural responses in patients suffering from post-concussion syndrome

Machine Learning based framework for ERPs analysis

vigil of the hypnosis state. Variables such as sex, level of hypnotic depth, Relative Power, Absolute Power, Total Absolute Power, Median Frequency and Total Median Frequency were analyzed. They were used as summary measures the percentage, the …

Normal brain response to propofol in advance of recovery from unresponsive wakefulness syndrome

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 …

A rapid ERPs (ERP) method for point-of-care evaluation of brain function: Development of the Halifax Consciousness Scanner

Background: ERPs (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. New …
