Reliable components
Baseline to peak amplitude, peak
latency
Use latency window established
using grand mean data

waveform (response to deviant)
Baseline to peak amplitude, peak
latency
Consider mean MMN amplitude
in response window
Use latency window established
using grand mean data
Response

Determined by
Replicable components
Response 2-3x larger than
amplitude in prestimulus interval
Replicable components
Response 2-3 times larger than
amplitude in prestimulus interval
