Okun, M. orcid.org/0000-0002-7795-5513 (2017) Artefactual origin of biphasic cortical spike-LFP correlation. Journal of Computational Neuroscience, 42. pp. 31-35. ISSN 0929-5313
Abstract
Electrophysiological data acquisition systems introduce various distortions into the signals they record. While such distortions were discussed previously, their effects are often not appreciated. Here I show that the biphasic shape of cortical spike-triggered LFP average (stLFP), reported in multiple studies, is likely an artefact introduced by high-pass filter of the neural data acquisition system when the actual stLFP has a single trough around the zero lag.
