ERP components in response to pitch and rule deviants, by electrode.
Conditions: (a) rule, (b) pitch. Shown are difference amplitude waveforms, Deviant minus Standard, for each of the electrodes. For each electrode a confidence interval (CI) was computed based on the 500 ms silent baseline period preceding sound presentation. Dashed horizontal lines represent the 2.5 and 97.5% CI boundaries. Where the waveform breached the CI, the timepoints during the breach were combined to create a single time window. The plots on the right show the grand average difference plot across all electrodes. The boxes indicated the significant components. In the rule condition there were two significant components, an MMR at 216–344 ms and a LP at 655–747 ms. For the pitch condtion there was an MMR at 159–316 ms and a LP at 469–515 ms.
