Events prediction in electroencephalographic signals
Brain Machine Interface (BMI) or Brain Computer Interface (BCI) technologies provide the prospect of regenerating or replacing functions lost due to motor disabilities. BCIs connect the brain to a computer which translates the electrical activity of the brain into commands used to control external …

Optimizing the Analysis of Electroencephalographic Data by Dynamic Graphs
… and redundant ones. In this study, we use electroencephalographic (EEG) brain signals, taken from recordings in 5 different experimental conditions, to generate the dynamic graphs by moving a sliding win- dow over the time series. Dynamic graphs are produced under various conditions that …

ELECTROENCEPHALOGRAPHIC AND ELECTROMYOGRAPHIC BIOFEEDBACK TRAINING OF OCCIPITAL LOBE THETA RHYTHM
<p>Three biofeedback training methods were used to train human subjects to enhance levels of occipital lobe theta electro-encephalographic rhythms. It was hypothesized that the subject's level of physiological arousal would differentially influence the effectiveness of the training methods. The …

A Bayesian Approach to the Characterization of Electroencephalographic Recordings in Premature Infants
… particularly susceptible to cerebral injury, and electroencephalographic: EEG) recordings provide an important diagnostic tool for determining cerebral health. However, interpreting these EEG recordings is challenging and requires the skills of a trained electroencephalographer. Because these EEG …

Sensing the human alpha rhythm using a non-contact electroencephalographic (EEG) electrode
<p>The electroencephalogram is the recording of bioelectrical potentials on the scalp due to neural current sources in the brain and are typically recorded using wet surface electrodes that make ohmic contact with the scalp surface using an electrolyte gel. Unfortunately, wet electrodes are …

Electroencephalographic effects of general anaesthetics : a suite of clinical studies and theoretical models
… of empirically-measured, anaesthesia-induced electroencephalographic (EEG) changes that could be explained by network models of cortical interactions. The thesis consists of a collection of various theoretical and clinical papers in three sections: (a) A background section summarizing previous …

Electroencephalographic (EEG) biofeedback treatment for children with attention deficit disorders in a school setting.
The purpose of this study was to explore the use of EEG biofeedback in a school setting to assist students who had attentional challenges. The equipment for implementing biofeedback was relatively inexpensive and was easily integrated into the school setting. Twenty students ranging in age from 7 …

Examining daily quantitative electroencephalographic (qEEG), psychophysical and antropometric measures over a one week period.
… measurement tool. Saturated (daily) quantitative electroencephalographic (qEEG) measurements for 7 days after a sports-related concussive injury and for 7 days about 8 months later revealed conspicuous changes in power measurements in specific frequency bands over the impact site as well as within …

Metabotropic glutamate receptors as targets for antiepileptic drug therapy: a behavioral and electroencephalographic analysis
Epilepsy is a relatively common neurological disorder that involves recurrent seizures thought to be caused by an imbalance in the excitatory and inhibitory systems in the brain, in favor of excitation. Unfortunately, some types of epilepsy have drug resistance rates of up to 40%. Classically, …

Electroencephalographic and Cognitive Underpinnings of Inhibitory Control in Obsessive-Compulsive Disorder: From Actions to Thoughts
… Deficits in inhibitory control correlate with electroencephalographic markers, especially error monitoring and action tendencies; (v) Habitual and ritualistic actions in OCD are driven by both motor deficits and intolerance of uncertainty; (vi) Learning and practising a finger tapping sequence …

Using Machine Learning Techniques to Model Encoder/Decoder Pair for Non-invasive Electroencephalographic Wireless Signal Transmission
<p>This study investigated the application and enhancement of Non-Invasive Brain-Computer Interfaces (NI-BCIs), focused on enhancing the efficiency and effectiveness of this technology for individuals with severe physical limitations. The core research goal was to improve current limitations …

A Pilot Study Using Machine Learning for Classification of Pain-Related Versus Non-Pain-Related Electroencephalographic Activity in Preterm Infants
Effective pain assessment and management are crucial to mitigate both immediate and long-term consequences of prolonged NICU stays. Accurately assessing pain in premature infants is challenging due to their inability to verbally communicate their pain, the potential judgement bias by caregivers, …
