Joint time-frequency analysis and filtering of single trial event-related potentials.
… electrical activity of the brain is known as the electroencephalograph (EEG). Event related potentials (ERPs) are voltage deviations in the EEG elicited in association with stimuli. Their elicitation require cognitive processes such as response to a recognised stimulus. ERPs therefore provide …

Machine Learning Methods for functional Near Infrared Spectroscopy
… as it has a better spatial resolution than the Electroencephalograph (EEG) device that is most commonly used in Human Computer Interaction studies under ecologically valid settings. But this key advantage of fNIRS device is underutilized in current literature in the fNIRS domain.</p> <p>We …

The Effects of Fluency-Based Instruction on Skill Acquisition in Children Diagnosed with Landau Kleffner Syndrome
… appearance of paroxysmal (i.e., sudden intense) electroencephalograph (EEG) activity (Pearl, Carrazana & Holmes, 2001). Landau Kleffner syndrome results from an epileptogenic lesion arising in the speech cortex during a critical period of development, which may interfere with the establishment of …

The Effects of Physiological Stress on Brain-Computer Interface Systems
… may impact the performance of a BCI device on an Electroencephalograph (EEG) signal level. The human stress response is a universal survival mechanism that impacts both the emotional and physiological state of the body. While it is known that acute stress directly affects mental performance, its …

A Physiological Signal Processing System for Optimal Engagement and Attention Detection.
… and the person not being attentive. Furthermore, Electroencephalograph (EEG) signals are also analyzed and classified for use as a benchmark for comparison with ECG analysis. For the study, ECG signals and EEG signals of volunteer subjects are acquired in a controlled experiment. The experiment is …

Pharmacokinetic and Pharmacodynamic Modelling to Advance Perioperative Anaesthesia and Analgesia
… I then developed a model describing processed electroencephalograph (EEG) response, using Bispectral Index (BIS), for multiple drug classes. I aimed to establish a model that could be used to simulate EEG response, as a cue of anaesthetic depth, in a human patient simulator (HPS). I developed a …

Human control of robots over discrete noisy channels with high latency: toward efficient EEG-based brain-robot interfaces
… at high latency from a human user (e.g., with an electroencephalograph) to control a robotic system (e.g., a robotic wheelchair) that can provide visual feedback. In this framework, the human user communicates their intent by providing inputs in response to queries posed by the robot. The …

USE OF BIOMETRICS TO DETERMINE BIOCHEMISTRY KNOWLEDGE LEVEL DIFFERENCES IN READING AND PROCESSING METABOLIC PATHWAYS
… co-registered systems of eye-tracking and electroencephalograph (EEG) followed by separate analysis. The experiment was conducted using 45 participants with varying levels of expertise in biochemistry. Through a post-survey, the participants were found to have different levels of …

The development of a SmartAbility Framework to enhance multimodal interaction for people with reduced physical ability.
… involving monitoring brain activity using an electroencephalograph (EEG), tracking facial features through Tracking Learning Detection (TLD), applying iOS Switch Control to track head movements and investigating smartglasses. - Results of controlled usability evaluations comparing multimodal …

Electrophysiological, observed, and subjective emotional responses to infant vocalizations: the role of adult attachment
… reduced relative left (vs. right) frontal EEG asymmetry from rest indicative of decreased positive emotion, lower observed tension, and decreased reported feelings of positive emotion in response to infant crying. In contrast, secure base script knowledge was not found to be significantly …

Sampling Controlled Stochastic Recursions: Applications to Simulation Optimization and Stochastic Root Finding
… the problem of probabilistically deciphering the electroencephalograph (EEG) signals recorded from the brain of a paralyzed patient attempting to perform one of a specified set of tasks. Monte Carlo simulation in this context takes a more general view, as the act of drawing an observation from a …

Hangry Minds, Unhealthy Choices: EEG Microstate Dynamics as Predictors of Goal-Dependent Dietary Self-Control
… computerized loss-of-control task. Resting-state EEG was recorded prior to task engagement to assess microstate stability. Behavioral results showed that hunger reliably biased choices toward tastier, less healthy foods. However, activating health goals promoted healthier decisions regardless of …
