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 interface 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 ... -
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 ... -
The Influence of Central Neuropathic Pain in Paraplegic Patients on Performance of a Motor Imagery Based Brain Computer Interface
(2015)Objective The aim of this study was to test how the presence of central neuropathic pain (CNP) influences the performance of a motor imagery based Brain Computer Interface (BCI). Methods In this electroencephalography ... -
Investigating accuracy of trade-off and its neural correlates, how well can we trade apples for oranges?
(Trinity College Dublin. School of Psychology. Discipline of Psychology, 2018)As humans, we perform trade-off of incommensurable concepts on daily basis. For example, many of purchase decisions, especially those involving complex products with multiple incommensurable attributes, require us to trade ... -
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 ... -
Movement-related cortical potentials in paraplegic patients: abnormal patterns and considerations for BCI-rehabilitation.
(2014)Non-invasive EEG-based Brain-Computer Interfaces (BCI) can be promising for the motor neuro-rehabilitation of paraplegic patients. However, this shall require detailed knowledge of the abnormalities in the EEG signatures ... -
Network Analysis in Motor Neuron Diseases: A Cortico-Muscular Coherence Study
(Trinity College Dublin. School of Medicine. Discipline of Clinical Medicine, 2022)Neurodegenerative conditions are associated with widespread changes in the motor networks. There is preliminary evidence from (f)MRI studies that the structural changes extend beyond the primary motor areas in cortical ... -
Neural evidence accumulation persists after choice to inform metacognitive judgments.
(2015)The ability to revise one's certainty or confidence in a preceding choice is a critical feature of adaptive decision-making but the neural mechanisms underpinning this metacognitive process have yet to be characterized. ... -
Neurophysiological markers of network dysfunction in neurodegenerative diseases
(Elsevier, 2019)There is strong clinical, imaging and pathological evidence that neurodegeneration is associated with altered brain connectivity. While functional imaging (fMRI) can detect resting and activated states of metabolic activity, ... -
Neurophysiology of Human Perceptual Decision-Making
(2021)The discovery of neural signals that reflect the dynamics of perceptual decision formation has had a considerable impact. Not only do such signals enable detailed investigations of the neural implementation of the ... -
Parametric models and spectral analysis for classification in brain-computer interfaces
(IEEE, 2002)Parametric modelling strategies and spectral analysis are explored in conjunction with linear discriminant analysis to facilitate an EEG based direct-brain interface for use by disabled people. A self-paced typing exercise ... -
Predictive and explanatory models of cigarette smoking: Computational approaches to understanding nicotine addiction
(Trinity College Dublin. School of Psychology. Discipline of Psychology, 2019)Smoking is the leading cause of preventable death worldwide, causing 6 million deaths every year (WHO, 2011). Most people try smoking for the first time in adolescence (O?Loughlin et al., 2014), making this a critical ... -
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 ... -
Resting-state electroencephalographic biomarkers for tracking cognitive network dysfunction in amyotrophiclateral sclerosis
(Trinity College Dublin. School of Medicine. Discipline of Clinical Medicine, 2024)Amyotrophic lateral sclerosis (ALS) stands as a multifaceted neurological disorder that primarily affects both upper and lower motor neurons. However, research in neuroimaging, neuropsychology and neurobiology has shown ... -
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 ...
