[human-electrophysiology] Any ideas about summing ERPs?

Hello all,


I wondered if anyone had any experience in 'summing' ERP waves.


We are using a formula AVF = (A + V) - AVF


AVF = responses to Audio/visual stimuli 

A = responses to Audio stimuli

V = responses to Visual stimuli


We are hoping to see an interaction effect, but I am a little unclear about
how to sum the ERPs.  We are using Brain Vision Analyser, does anyone have
any ideas?


Many thanks,
