Effects of Monotonous Auditory Stimulation on the Human EEG
Human EEG Monotonous Auditory Stimulation Music Frequency Bands Cortical Micropotentials
2013/1/30
Monotony is the result of continuous predictive or repetitive stimulations and can be considered a functional state of the central nervous system, a state characterized by lowered cerebral activity. T...
A Preliminary Study on Early Diagnosis for Dementia Using EEG Topography during Sternberg Task
working memory sternberg task EEG topography theta band
2009/8/24
Our goal is to establish an early diagnostic method for dementia by electroencephalography (EEG) usinga working memory task (Sternberg task). We studied four dementia patients and eighteen healthy sub...
Representation of the Characteristics of Dominant Rhythm and Automatic EEG Interpretation Method Using an EEG Model
electroencephalogram (EEG) EEG model automatic EEG interpretation dominant rhythm trend artifact
2009/6/9
In the proposed method, an EEG model that takes account of trend artifacts is constructed to separate the trend artifacts from the background EEG, and specific EEG parameters for each judgment are cal...
Analysis of Cortical Potential in Bimanual Alternate Finger Tapping by Dense-Array EEG System
Hiroshi FUKUDA Masato ODAGAKI Osamu HIWAKI
2009/6/2
Using high-density electroencephalography (EEG) , the brain regions involved in tapping of the index fingers were investigated. Subjects were requested to perform voluntary alternate tapping movements...
A Novel Segmentation, Mutual Information Network Framework for EEG Analysis of Motor Tasks
Mutual Information Network Framework EEG Analysis Motor Tasks
2010/2/25
Monitoring the functional connectivity between brain regions is becoming increasingly important in elucidating brain functionality in normal and disease states. Current methods of detecting networks i...
Evolutionary optimization of classifiers and features for single-trial EEG Discrimination
single-trial EEG Discrimination Evolutionary optimization
2010/2/25
High degrees of classifier parameter, structure and feature subset tailoring on individual levels substantially increase single-trial EEG classification rates, an important consideration in areas wher...
Nonlinear analysis of EEG signals at different mental states
Nonlinear analysis EEG signals different mental states
2010/3/1
It is found that the measures are significantly lower when the subjects are under sound or reflexologic stimulation as compared to the normal state. The dimension increases with the degree of the cogn...
Effects of dipole position, orientation and noise on the accuracy of EEG source localization
dipole position orientation and noise EEG source localization
2010/3/1
It was found that if the signal-to-noise ratio is above a certain threshold, localization errors in realistic head models are, on average the same for deep and superficial sources. As the noise increa...
From wavelets to adaptive approximations: time-frequency parametrization of EEG
wavelets adaptive approximations time-frequency parametrization EEG
2010/3/1
This paper presents a summary of time-frequency analysis of the electrical activity of the brain (EEG). It covers in details two major steps: introduction of wavelets and adaptive approximations. Pres...
