WebMay 31, 2012 · In the experiment, event-related potentials (ERPs) were recorded while participants heard frequently sung consonant-vowel syllables and rare stimuli deviating in either consonant identity only, pitch only, or in both dimensions. Every type of deviation elicited a reliable MMN. WebSubjects were presented 1600 binaural tone pips (3/second) comprising 1520 standards (75 dB, 1 kHz, 100 ms duration, 10 ms rise/fall) and 80 pitch-deviants (75 dB, 1.2 kHz, 100 ms duration, 10 ms rise/fall). Tone intensities were verified with a soundmeter.

The deviants were otherwise identical to standards. Sound intensity was 56 dB SPL at the subject‘s head. WebJun 16, 2024 · MMN to pitch-deviants (pMMN) and duration-deviants (dMMN) are …
WebMay 11, 2016 · The overall effect size showed no MMN reduction in first-episode patients to pitch-deviants (Cohen’s d < 0.04), and a small-to-medium reduction to duration-deviants (Cohen’s d = 0.47). Together, this indicates that pitch-deviant MMN is not a candidate biomarker for schizophrenia prediction, while duration-deviant MMN may hold some …
