Electroencephalography of premature infants
… model incorporated simultaneous multi-channel electroencephalography (EEG), peripheral oxygen saturation (SpO2), and heart rate (HR) recordings. One-hour epochs of EEG, HR and SpO2 were then extracted at 12 and 24 hours of age from each recording. EEG grades were combined with GA and …

Electroencephalography in a Teaching Hospital
<p>Electroencephalography may be defined as a study of the electrical activity of the brain. This activity was first recorded and reported by Caton in 1875. However, it was the work of Hans Berger, confirmed by Adrian and Matthews in 1935, which opened the way for the rapid advancement of knowledge …

Electroencephalography for neurological prognostication after cardiac arrest
This thesis focuses on the prognostic value of electroencephalography(EEG) in comatose patients resuscitated after cardiac arrest (CA), using both simplified continuous EEG monitoring (cEEG) and routine EEG. Background: Comatose survivors are admitted to an intensive care unit (ICU) to support …

Automated Detection And Quantification Of Pain Using Electroencephalography
… longitudinal evaluation of pain therapies. With electroencephalography (EEG) gaining traction as a reliable tool for characterizing brain regions active during pain, this work presents the development of robust and accurate machine learning algorithms on neuroimaging data using EEG to detect and …

SINGLE-CHANNEL REAL-TIME DROWSINESS DETECTION BASED ON ELECTROENCEPHALOGRAPHY
… detection system based on a single-channel electroencephalography (EEG). Towards that goal, we introduced three main contribution proposed in this thesis: (1) a real-time drowsiness detection algorithm based on EEG suitable for portable applications with low computational complexity; (2) …

Neurophysiological correlates of preparation for action measured by electroencephalography
… in this thesis, I employed high-density electroencephalography in order to study the neural processes underlying preparation for action. A typical way for studying preparation for action in neuroscience is to divide it in temporal preparation (when to respond) and event preparation (what …

Evaluating social and cognitive effects of video games using electroencephalography.
… GUR methodology, this thesis explores ways that electroencephalography (EEG) can be used as an evaluative measure as part of a mixed methodology. The thesis aims to improve the accuracy and richness of GUR results obtained using EEG. Hemispheric Frontal Alpha Asymmetry (HFAA) is reviewed in depth …

Topic Modeling for Inferring Brain States from Electroencephalography (EEG) Signals
<p>Inferring brain states from EEG signals allows for the management of sleep disorders and brain diseases by providing an insight into the electrophysiological state of the brain. We explore the use of topic modeling – which are popular text processing algorithms – to infer brain states from EEG …

Applied Error Related Negativity: Single Electrode Electroencephalography in Complex Visual Stimuli
Error related negativity (ERN) is a pronounced negative evoked response potential (ERP) that follows a known error. This neural pattern has the potential to communicate user awareness of incorrect actions within milliseconds. While the implications for human-machine interface and augmented …

Intracranial electroencephalography signatures of the induction of general anesthesia with Propofol
… networks responsible for the characteristic electroencephalography (EEG) signals of anesthesia in relation to sensory, cognitive, memory, and pain systems. In this thesis, we recorded simultaneous intracranial and surface EEG, and single unit data in patients with intractable epilepsy who had …

Towards a neurophysiological correlate of the precedence effect: from psychoacoustics to electroencephalography
The general goal of this thesis was to find a neurophysiological correlate of the precedence effect in humans and to shed light on the question on which stage of the auditory pathway information related to the precedence effect is processed. Investigations were made by means of psychoacoustics and …

Computational Methods and Analyses for Assessing Cerebellar Electrophysiology with Magneto- and Electroencephalography
… remains poorly characterized. Magneto- and electroencephalography (M/EEG) can non-invasively and directly measure neural activity at sub-millisecond temporal resolution and therefore hold promise to bridge this gap. M/EEG has, however, so far mainly been employed to study the cerebral cortex …

On Controlling a Pediatric Lower-Limb Exoskeleton Using Finite-State Machine and Electroencephalography
… P-LEGS that can utilize explicit manual input or electroencephalography (EEG) signals to command the device to generate movement trajectories. The process of developing, evaluating, and prototyping the various levels of control for the system, as well as the proposed movement intent decoding …

Modulations of Electroencephalography signals in Response to experimental pain During Single Leg Cycling exercise
… been applying neuroimaging techniques such as electroencephalography (EEG) to elaborate on the brain's electrical activity and the cortical regions involved in the complex coordination of movements during exercise. Pain experienced during high-intensity exercise is an “inhibitory factor” that …

Study of the Term Neonatal Brain Injury with combined Diffuse Optical Tomography and Electroencephalography
… of combined diffuse optical tomography (DOT) and electroencephalography (EEG) in the investigation of neonatal term brain injury. With hypoxic ischaemic encephalopathy (HIE) and perinatal stroke being the most frequent contributors to brain injury in the term neonatal population, the first part of …
