Why doesn't an electrochemical artifact look like a seizure?
However, electrographically it doesn't look like a seizure or interictal activity, either, for several reasons. First, it doesn't match a seizure because it is non-evolving and less than ten seconds, Second, it doesn't look like interictal activity because it doesn't disturb the background (it doesn't have a physiologic field); you may accidentally think there's a field because there is involvement of both the temporal and parasagittal chains, but note that within those chains, outside of the electrodes involved, there is no disruption of the background (for example, in the temporal chain F7-T3 and T3-T5 are involved, but Fp1-F7 isn't at all, and likewise for Fp1-F3 and F3-C3 in the parasagittal chain). Electrode artifact can often mimic positive phase reversals like this.
