The Interaction of Intensity and Deviance on Auditory Event-Related Potentials: Findings Using Principal Component Analysis (PCA) of Current Source Densities (CSDs)
… of varying levels of intensity deviance on N1/P2 with a standard set of intensities used in LDAEP paradigms, and b) assess the extent to which deviance-related processes (indexed by MMN) are affected by louder or softer tones. A passive MMN-paradigm used the same stimuli as deviants and …

Neural Correlates of Auditory -Visual Speech Perception in Noise
… with response time and accuracy measures and the N1/P2 ERP waveform response as a function of changes in audibility (manipulation of the acoustic environment by testing a range of signal-to-noise ratios) and content of optic cue (manipulation of the types of cues available, e.g., speech, …

Event-related potentials during auditory discrimination: attentional and intentional effects
… were measured for four event-related potentials (N1, P2, N2, and P3) at three midline electrode sites (Fz, Cz, pz) and eight bilateral sites (Fp1, Fp2, F3, F4, C3, C4, P3, P4). Measures from the midline and bilateral sites were subjected to separate repeated measures ANOVAs for within subjects …

Electrically Evoked Auditory Potentials Recorded at Three Levels of the Auditory Pathway From Multichannel Cochlear Implant Subjects: Characterization and Comparison to Behavioral Measures
… of either the Wave V, the Na-Pa complex, or the N1-P2 complex may be used to select stimulus levels that are audible for subjects, although the location of the EPT within the behavioral dynamic range varied across subjects. The poorest performers on measures of speech recognition had the smallest …

The Effects of Selective Serotonin Reuptake Inhibitors (Ssri) on Auditory Measures in Clinically Depressed Subjects.
… larger amplitude at 45 dBnSL for the N1/P2 component for the unmedicated group. Although the other measures showed trends, they did not reach significance.

Development of Computerized Multicomponent Cognitive Stimulation for Improving Cognitive Functions in Older Adults with Mild Cognitive Impairment: A Multimodal Investigation Using Neuropsychological and EEG/ERP Assessment
… for band frequencies, and ERP components such as N1, P2, P3, N4, and P6 were explored. Additionally, depression, anxiety, and quality of life were measured. Data were analyzed primarily using analysis of covariance, with posttest scores as the dependent variable and pretest scores as the …

The relationship between self-prioritization, reward-prioritization and emotion-prioritization effects; an EEG study.
… related potentials (ERPs) were analysed for P1, N1, P2, N2 and P3 components. Shape-label matches for self compared with stranger labels evoked a significant decrease in posterior P2 amplitudes (223ms) and a significantly greater amplitude of P300 (336ms) for self- relevant stimuli. We found a …

Electrophysiological and behavioural measures of central auditory processing in adult cochlear implant users
… years).Middle latency response (MLR), obligatory N1-P2 cortical potentials, mismatch negativity and P3a auditory evoked potential were recorded. Speech perception was evaluated using tests from "The Minimum Speech Test Battery for Adult Cochlear Implant Users". Frequency discrimination was …

Cortical auditory processing of informational masking effects by target-masker similarity and stimulus uncertainty
… Responses were recorded simultaneously for P1-N1-P2 (standard waveform) and P3 (target waveform). This design allowed for simultaneous recording of multiple AEP peaks, including analysis of amplitude, area, and latency characteristics, as well as accuracy, reaction time, and d’ behavioral …
