[Eeglablist] EEG questions

I'm really sorry to post to this group, but I've been playing with EEGLAB
and - being new to EEG - have some basic dumb questions. If anyone could
point me in the right direction, I'd appreciate it.
- Is there any consensus on the spatial resolution of a typical scalp
electrode? What is the smallest volume whose activity one can expect to
represent with scalp EEG? How deep a structure can contribute? I'm not
asking about the resolution of any particular algorithm like ICA, but the
physical limits of scalp-recorded EEG.
- Has there been any work done on the capacitive effects with scalp EEG,
both in terms of head models and electrodes?
Thank you in advance to whoever may have an answer or a place to look, and
apologies again if it's an inappropriate post.
