suppressed with stimulus repetition. In addition, we observed the emergence of a sustained field (~230–270 ms)
that showed RE. Source analysis revealed neuronal generators of RS and RE located in both auditory and
non-auditory areas, like the medial parietal cortex and frontal areas. The different timing and location of neural
generators involved in RS and RE points to the existence of functionally separated mechanisms devoted to acoustic
memory-trace formation in different auditory processing stages of the human brain
