Grand averaged ERP P3a was elicited by a three-stimulus (novelty) auditory oddball paradigm for the ND group (purple lines and green lines) and the HC group (black lines and red lines) at time 1 and time 2. The P3a components were presented within a 250–450 ms latency window at the Cz electrode site.
