Asymmetric random matrices: What do we need them for?
Stanislaw Drozdz, Jaroslaw Kwapien, Andreas A. Ioannides
Complex systems are typically represented by large ensembles of observations. Correlation matrices provide an efficient formal framework to extract information from such multivaria…
Temporal correlations versus noise in the correlation matrix formalism: an example of the brain auditory response
J. Kwapien, S. Drozdz, A. A. Ioannides
We adopt the concept of the correlation matrix to study correlations among sequences of time-extended events occuring repeatedly at consecutive time-intervals. As an application we…
Collectivity in the Brain Sensory Response
S. Drozdz, J. Kwapien, A. A. Ioannides +1
A question of cooperative effects in auditory brain processing on various space- and time-scales is addressed. The experimental part of our study is based on Multichannel Magnetoen…
Cooperative dynamics in auditory brain response
J. Kwapien, S. Drozdz, L. C. Liu +1
Simultaneous estimates of the activity in the left and right auditory cortex of five normal human subjects were extracted from Multichannel Magnetoencephalography recordings. Left,…
