Coherence and Phase Synchrony Analysis of Electroencephalogram
… for the specific purpose of processing of the electroencephalogram (EEG). We propose the Phase Synchrony Processor (PSP), as a tool for implementing phase synchrony analysis, and examine its properties on the basis of known signals. Long observation times and wide filter bandwidths can decrease …

Music and the Brain: Composing with the Electroencephalogram
The field of brain-computer music interfaces have been expanding ever since the first development in the 1960s. Although many brain-computer music interfaces have been developed for the purpose of composing music, these systems have not been accessible to musicians due to the use of complex …

An Electroencephalogram Investigation of Two Modes of Reasoning
The use of electroencephalography (EEG) to exam the electrical brain activity associated with reasoning provides an opportunity to quantify the functional and temporal aspects of this uniquely human capability, and at the same time expand our knowledge about what a given event-related potential …

Mutual information derived functional connectivity of the electroencephalogram (EEG)
Monitoring the functional connectivity between brain networks is becoming increasingly important in elucidating brain functionality in normal and disease states. Current methods of detecting networks in the recorded EEG such as correlation and coherence are limited by the fact that they assume …

A Consensus Model for Electroencephalogram Data Via the S-Transform
… we will consider 32 signals produced by a single electroencephalogram (EEG) recording session. The consensus model will be produced by using the S-Transform of the individual signals and then normalized to unit energy. A bootstrapping process is used to produce a consensus spectrum. This leads to …

Epileptic Seizure Detection And Prediction From Electroencephalogram Using Neuro-Fuzzy Algorithms
… epileptic seizure detection and prediction from Electroencephalogram (EEG). The fuzzy rule-based algorithms were developed with the aim to improve quality of life of epilepsy patients by utilizing intelligent methods. An adaptive fuzzy logic system was developed to detect seizure onset in a …

Neural network security and optimization for single-person authentication using electroencephalogram data
… interfaces (BCIs), which often use electroencephalogram (EEG) data as inputs and neural network classification to determine their function. EEG data can also serve as a form of biometric authentication, which would contribute to the security of these devices. Neural networks have …

Multimodal neuroimaging with simultaneous electroencephalogram and high-field functional magnetic resonance imaging
Simultaneous recording of electroencephalogram (EEG) and functional magnetic resonance imaging (tMRI) is an important emerging tool in functional neuroimaging with the potential to reveal new mechanisms for brain function by combining the high spatial resolution of fMRI with the high temporal …

Signal Processing of Electroencephalogram for the Detection of Attentiveness towards Short Training Videos
… an easy to deploy single dry electrode wireless electroencephalogram (EEG) collection device as an input to an automated system that measures indicators of a participant’s attentiveness while they are watching a short training video. The results are promising, including 85% or better accuracy in …

Complexity Analysis of Physiological Time Series with Applications to Neonatal Sleep Electroencephalogram Signals
This thesis investigates the complexity in physiological time series with application to neonatal sleep electroencephalography (EEG) signals. Complexity analysis is applied to two clinical data sets of neonatal sleep Electroencephalography(EEG) time series, to uncover the evolution of signal …

Case Studies of the Effects of Orienting Stimuli on the Electroencephalogram and Levels of Coma
… by Glasgow Coma Scale (GCS) scores and the electroencephalogram (EEG) in four comatose patients. The problems were: (1) to investigate whether brain activity was predictive in assessment of the comatose patient as measured by the EEG; (2) to investigate whether levels of coma were predictive …

A Psychophysiological Assessment of the Efficacy of Event-Related Potentials and Electroencephalogram for Adaptive Task Allocation
… study was designed to test the efficacy of using Electroencephalogram (EEG) and Event-Related Potentials (ERPs) for making task allocations decisions. Thirty-six participants were randomly assigned to an experimental, yoked, or control group condition. Under the experimental condition, a …

Classification of electroencephalogram (EEG) for lower limb movement of post stroke patients using artificial neural network (ANN)
Nowadays, many neurological conditions happen suddenly, such as stroke or spinal cord injury. This can cause chronic gait function impairment due to functional deficits in motor control. Current physiotherapy techniques such as functional electrical stimulation (FES) can be used to reconstruct some …

The electroencephalogram in manic-depressive psychosis : relationship to psychological features and implications for a toxic-organic pathogenesis.
This investigation was undertaken with a view in the first place to testing a claim of Pauline Davis as to the correlation, in manic-depressive psychosis, between certain psychological and electroencephalographic features, notably alpha frequency and irregular fast low voltage records which she …
