[Eeglablist] How many epochs to average for the ERP

[Tom Campbell]

Dear Imali, For the 10 commandments followed by a section on number of trials and signal:noise, please see:
Luck, S. J. (2005b). Ten simple rules for designing ERP experiments. In T. C. Handy (Ed.), Event-Related Potentials: A Methods Handbook (pp. 17-32). Cambridge, MA: MIT Press. http://mindbrain.ucdavis.edu/people/sjluck/pdfs/Luck%202005%20Ten_Simple_Rules.pdf

pg.30 may be where you want to start.

Best regards,

Subject: [Eeglablist] How many epochs to average for the ERP









Dear EEGLAB users,

 
I am planning to do an experiment of an ‘oddball’ paradigm , as a pilot test for the new EEG system in our lab. If anyone can give me some guidance on the following questions that will be really helpful and very much appreciated.
 
What is the usual practise used for the number of epochs to average to get the ERP? If we take , say three randomised runs of the oddball experiment for the same subject will averaging the extracted epochs from individual runs be valid
 for the ERP?
 
If anyone can direct me to some papers or references on experimental designs for ERP analysis that will be greatly appreciated.
 
Many thanks in advance.
 
Regards
Imali
