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.}, URL = {https://www.biorxiv.org/content/early/2016/04/29/051029}, eprint = {https://www.biorxiv.org/content/early/2016/04/29/051029.full.pdf}, journal = {bioRxiv} }
