Duration and pitch deviants
WebWe presented a duration deviant and a pitch/duration deviant in this study. Literature has shown that duration MMN was more robust in separating controls from schizophrenia patients than pitch MMN (e.g., Magno et al. 2008). Duration deviant was therefore our primary task. At the mean time, we explored whether one version of the duration/pitch ... WebJul 1, 2012 · Moreover, they used a non-linguistic sequence (standard=1000 Hz, 250 ms) with deviants in frequency (1100 Hz, 250 ms) and duration (1000 Hz, 175 ms). Dyslexics displayed longer MMN latency than controls for all linguistic contrasts and for vowel duration deviants, as well as for the frequency deviants in pure tones.

Current results suggest that tDCS seems to have a variable effect on the different generators.
