[edit] Introductory sentence

Similar to the discussion in Talk:Visual_evoked_potential, can the "In neurophysiology" phrase be removed from the opening sentence? Edwardian 04:18, 7 August 2005 (UTC)

Yes. Whether neurophysiology or not, an evoked potential is always the same thing. Dontaskme 22:52, 12 September 2005 (UTC)

[edit] EEG includes EPs

The article currently suggests that EEG and evoked potentials are completely unrelated. My understanding is that evoked potentials are a component of the EEG. In other words, the EEG is a mix of (a) the evoked potential, (b) spontaneous/ongoing/"background" activity, (c) misc. other things, (d) possibly interactions between the aforementioned components. The article should at least reflect that the EP is a part of the EEG. Dontaskme 22:49, 12 September 2005 (UTC)

Both components are in the EEG, if you mean the actual voltages on the skalp, but the displayed measement results are distinct: You (usually) can't see the EP in a display of EEG traces as it is so much smaller, and you can't see the (background) EEG in an EP display as it averages out. I'll try to clarify this in the article. --Pjacobi 08:17, 13 September 2005 (UTC)

I meant exactly what you are saying. An EP usually cannot be identified in an EEG trace, but it's nevertheless hidden in there (and can be extracted through averaging of multiple trials). Dontaskme 18:41, 13 September 2005 (UTC)

I appreciate the talk, but you should write info in the article, not in the talk page. Yoiu17 06:41, 13 December 2006 (UTC)
