EFFECTS OF ACUTE THC ADMINISTRATION ON EXTINCTION OF CONDITIONED FEAR RESPONSES IN HUMANS: A FUNCTIONAL ANALYSIS OF HIGH DENSITY EEG
High density electroencephalographic (EEG) measures were used to assess the effects of acute delta 9-tetrahyrdrocannabidol (THC) administration on extinction of conditioned fear responses. Fear conditioning was initiated using a differential classical conditioning paradigm that paired an aversive …

Machine-Learning-Based Approach to Decoding Physiological and Neural Signals
… This is particularly challenging due to the highly non-linear, non-stationery, and artifact- and noise-prone nature of these signals.</p> <p>Among basic human-control tasks, reaching and grasping are ubiquitous in everyday life. I investigated different linear and non-linear dimensionality …

EEG theta oscillations during sleep deprivation
… characterize the electroencephalogram (EEG) during distinct cognitive and vigilant states. Theta oscillations (4-8 Hz) are unusual because they have been found in the near-opposite conditions of sleepiness and alert cognitive control. Most neuroscience research fo-cuses exclusively on …

About turn:neural mechanisms underlying visual processing of rotated letters and digits
… neural processing was monitored with high-density EEG. In Experiment 2 participants performed the same two tasks, while in Experiment 3 they performed the category task and red-blue colour judgements. In Experiment 1, linear increases in fMRI activation were elicited only by the parity …

Neural Underpinnings of Walking Under Cognitive and Sensory Load: A Mobile Brain/Body Imaging Approach
… biomechanical measures, of the recruitment of higher-level cortical resources during gait. Additionally, recent EEG and imaging (PET, fNIRS) studies have revealed direct neurophysiological evidence of cortical contributions to steady-state walking. However, there remains a lack of knowledge …

Neural Dynamics of Mental Imagery, Visual Perception, and Rapid Eye Movement Sleep
… disorders provided electroencephalography (EEG) data, while other participants provided intracranial data with electrodes surgically implanted as part of their epilepsy treatment plan. Both sets of human participants were monitored during visual stimulus processing, imagery, and REM sleep. …

EXPLORING PHYSIOLOGICAL, PATHOLOGICAL AND PARAPHYSIOLOGICAL BRAIN ACTIVITY ACROSS SCALES WITH SIMULTANEOUS INVASIVE AND NON-INVASIVE EEG
… thesis explores the integration of non-invasive high-density electroencephalography (hd-EEG) with invasive stereoelectroencephalography (SEEG) to enhance understanding of brain electrophysiology in pathological, physiological and paraphysiological contexts. The combination of these two methods, …

Signal Processing Methods for Reliable Extraction of Neural Responses in Developmental EEG
… in newborns and infants. Electroencephalography (EEG) is one of the most optimal neuroimaging technique to investigate neurocognitive functions in human newborns because it is non-invasive and quick and easy to mount on the head. Since EEG offers a versatile design with custom number of …

Cortical Reorganisation in Complex Regional Pain Syndrome (CRPS)
… group. They can be used to identify patients at high risk of developing chronic pain post-fracture thereby allowing targeted early intervention. Cortical reorganisation, defined as structural and functional changes within the cerebral cortex, is implicated in many chronic pain conditions …
