Multivariate and wavelet techniques of spontaneous electroencephalography and event related potentials during children maturation: The role of phase resetting
Description
The purpose of this study is to analyze whether the
maturation of spontaneous EEG occurs at the same
rate as Late Positive Component (LPC) maturation.
To that end, the spontaneous EEG rhythms power
spectral density (PSD) and the LPC component in a
group of children and a group of young adults were
obtained and analyzed by means of Spearman's correlation
coefficients, hierarchical clustering, Principal
Component Analysis (PCA) and topographical analysis.
The multivariate analysis revealed a co-maturation
of LPC with the delta band. This co-maturation was
more evident in the more posterior region. The multivariate
analysis results suggest that the maturation
of the two components is temporally closely associated.
The LPC in both children and young adults was
produced by a combination of increase of Event Related
Spectral Perturbation (ERSP) and phase resetting
in the delta band. It can be suggested that the
maturations of delta and LPC are functionally interdependent
due to a possible origin of LPC as a delta
phase resetting and/or because both processes depend
on the same fraction of synaptic pruning.
