suggests that RP might be a better human correlate of the
animal SSA than MMN. However, it is worth noting that RP represents
both an increase of P50 and P2, and a decrease of N1 components of
the auditory ERP, thus it is likely to involve both RS and RE in different
time-intervals. In addition, the resistance towards neural fatigue
shown at P50 and P2 components, and the stable scalp distribution
occurring across different experimental conditions
