A comparison of covert and overt attention as a control option in a steady-state visual evoked potential-based brain computer interface
(IEEE, 2004)EEG data were recorded from occipital scalp regions of subjects who attended to an alternating checkerboard stimulus in one visual field while ignoring a similar stimulus of a different frequency in the opposite visual ... -
Congruent Visual Speech Enhances Cortical Entrainment to Continuous Auditory Speech in Noise-Free Conditions.
(2015)Congruent audiovisual speech enhances our ability to comprehend a speaker, even in noise-free conditions. When incongruent auditory and visual information is presented concurrently, it can hinder a listener's perception ... -
The cortical representation of the speech envelope is earlier for audiovisual speech than audio speech.
(2014)Visual speech can greatly enhance a listener's comprehension of auditory speech when they are presented simultaneously. Efforts to determine the neural underpinnings of this phenomenon have been hampered by the limited ... -
The impact of visual speech on neural processing of auditory speech
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)When we listen to someone speak, seeing their face can help us to understand them better, especially when there is background noise or other people speaking at the same time. Research examining the neural processes underlying ... -
Independent brain computer interfacing control using visual spatial attention-dependent modulations of parieto-occipital alpha
(2005)Parieto-occipital alpha band (8-14 Hz) EEG activity was examined daring a spatial attention-based brain computer interface paradigm for its potential use as a feature for left/right spatial attention classification. In ... -
Investigating the Neural Correlates of Speech Processing & Selective Auditory Attention using EEG
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2020)Speech comprehension is a remarkable human ability. Most normal-hearing people are adept at attending to a speech stream even amidst a noisy multi-talker background and parsing the layers of information it contains in ... -
Isolating neural indices of continuous speech processing from multivariate neural data
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2017)The human ability to understand speech is underpinned by a hierarchical auditory system whose successive stages process increasingly complex attributes of the auditory input. To produce categorical speech perception, it ... -
Probing the neural mechanisms of adult-onset isolated focal dystonia
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2018)Adult onset isolated focal dystonia (AOIFD) is inherited in an autosomal dominant manner with a reduced penetrance of 12-15%; cervical dystonia (CD) is the most common phenotype in northern Europe. It is believed that the ... -
Uncovering the effects of semantic context on the cortical processing of continuous speech using computational models of language
(Trinity College Dublin. School of Engineering. Discipline of Electronic & Elect. Engineering, 2021)The semantic context in which spoken words appear will greatly shape how they are understood by the human brain. This understanding is underpinned by a hierarchical system that processes increasingly abstract features of ...
