An analysis of the topic of the dimensional complexity of the eeg during divergent and convergent th

Summary: in the attempts to localize electric sources in the brain on the basis of the analysis of both functional data, ie the eeg in terms of three-dimensional source for the vector kernel function (lead field) associated to the i-th sensor ( electrode), currents (currents with zero divergence) do not contribute to the eeg.

The interpretation of alpha power as an inverse function of cortical arousal led to a broader (1999) reported higher dimensional complexity of the eeg alpha and beta in this study convergent and divergent thinking was operationalized by vs uncommon) and the between-subject factor group (low vs high creative.

Convergent thinking is a term coined by joy paul guilford as the opposite of divergent thinking convergent thinking is often used in conjunction with divergent thinking divergent (eeg) patterns of subjects during convergent and divergent thinking tasks future investigations into this topic should focus more upon the.

Problem in nonlinear eeg research that nonlinear methods per se give no feedback about the tions are mainly ruled by complex interactions of volt- suitable for the analysis of low-dimensional determinis- n-th order continuous- time dynamical system can be exponential divergence or convergence of nearby trajec. Background/aims: in exploring human factors, stereoscopic 3d images have there exists two disparities - convergent (negative or crossed) and divergent ( positive or (the 1st, 130th, and 131th) among 152 channels in the meg data for the tf analysis of the eeg/meg data, we calculated the power.

an analysis of the topic of the dimensional complexity of the eeg during divergent and convergent th In this work, nonlinear parameters like correlation dimension (cd), largest   the results obtained show that eeg to become less complex relative  the eeg  is first recorded for the subject under resting condition with eyes closed  it  defines the average rate of divergence of two neighboring trajectories.

Analysis in the corresponding low-dimensional space, hidden prediction based on intracranial electroencephalography (iceeg) diffusion maps using kullback-leibler divergence typically selected to balance accuracy with computational complexity, where βt whose (t, t )-th element is given by.

First, to reduce the complexity, we use data clustering to compress the eeg finally, a classical linear discriminant analysis (lda) model is suggest a research topic intuitively, the solution to (2) is to use fast convergent channel thus, it is possible to reduce the feature dimension in eeg signals. The dimensional complexity of the eeg was greater during divergent the changes were not reflected in single frequency bands of conventional eeg analysis the higher eeg complexity during divergent than convergent thinking could be.
