<p class="MsoNormal">Good call Tarik. P300 seems a good high amplitude component to start testing a lab out with on one healthy young adult using some form of oddball paradigm, before making adjustments to the lab. Trying out the real macoy is a good place
to start. The right number of trials to get a the signal:noise needed will depend on your lab and how you set it up. In practise, not every factor that causes noise can be always be identified, controlled, or eliminated. Various tests involving a bucket or
even a melon can be revealing about sources of external noise if this becomes a concern. T.<o:p></o:p></p>
