Linear and nonlinear causality between signals: methods, examples and neurophysiological applicationsBoris Gourévitch
Laboratoire Traitement du Signal et de l Image, INSERM U642, Universite de Rennes 1, Campus de Beaulieu, Bat 22, 35042, Rennes Cedex, France
Biol Cybern 95:349-69. 2006
..PNGC is extremely dependent on the choice of parameters. Moreover, LGC and PNGC may give misleading results in the case of causality on a spectral band, which is illustrated by our neurophysiological database...

J Comput Neurosci 29:253-77. 2010
..We also show that the combined use of firing rate and temporal codes leads to a better discrimination of the MF...
- Evaluating information transfer between auditory cortical neurons
Boris Gourévitch
Department of Physiology and Biophysics and Department of Psychology, University of Calgary, Calgary, Alberta, Canada
J Neurophysiol 97:2533-43. 2007
..The normalized transfer entropy shows similarities and differences with the strength of cross-correlation; these form the basis for revisiting the neural assembly concept...
- Spectro-temporal sound density-dependent long-term adaptation in cat primary auditory cortex
Boris Gourévitch
Department of Physiology and Biophysics, Department of Psychology, University of Calgary, Calgary, Alberta, Canada
Eur J Neurosci 27:3310-21. 2008
..Our findings suggest that low stimulus rates may produce a specific acoustic environment that shapes the primary auditory cortex through very different processing than for spectro-temporally more dense and complex sounds...
- Spectrotemporal receptive fields in anesthetized cat primary auditory cortex are context dependent
Boris Gourévitch
Department of Physiology and Biophysics, University of Calgary, Calgary, Alberta, Canada
Cereb Cortex 19:1448-61. 2009
..We thus emphasize some aspects of context dependency of STRFs, that is, how the balance of inhibitory and excitatory inputs is able to shape the neural response from the spectral content of stimuli...
