Figure Lengend Snippet: Median number of accepted and shared epochs for Neuroscan and EPOC by condition and tone type. Median (inter-quartile range) number of accepted epochs for the Neuroscan and EPOC systems and total number of epochs shared (i.e. accepted for both systems) between systems in each condition (passive and active) for each tone type (standard, deviant, and total). Wilcoxon Signed Rank Tests ( Z ) were used to test the difference between systems.

Figure Lengend Snippet: All graphs display the group average ERP waveforms for the passive (ignore tones) and active (count deviant tones) listening conditions. Data collected with Neuroscan and EPOC are presented in the left and right columns respectively, ERPs to the standard (low) tones are presented in panels A, B, E, & F, and ERPs to the deviant (high) tones are presented in panels C, D, G, & H. The upper four panels depicted ERPs from the left-hemisphere (Neuroscan = F3: A & C; EPOC = AF3: B & D) and the lower four panels depicted ERPs from the right-hemisphere (Neuroscan = F4: E & G; EPOC = AF4: F & H).

Figure Lengend Snippet: Neuroscan versus EPOC ERP and MMN waveform intraclass correlations. Mean intraclass correlations (ICC) (with 95% confidence intervals) between Neuroscan and EPOC late auditory P1, N1, P2, N2, and P3 ERPs and the MMN component at F3/AF3 and F4/AF4 to standard and deviant tones in both passive and active conditions. Single-sample Wilcoxon signed rank test p -values are represented.

Figure Lengend Snippet: Data collected with the Neuroscan and EPOC are presented in the left and right columns respectively, ERPs to the standard (low) and deviant (high) tones are presented in panels A, B, E, & F, and the difference between these waveforms (i.e., the mismatch negativity responses) are presented in panels C, D, G, & H. The upper four panels depicted ERPs from the left-hemisphere (Neuroscan = F3: A & C; EPOC = AF3: B & D) and the lower four panels depicted ERPs from the right-hemisphere (Neuroscan = F4: E & G; EPOC = AF4: F & H).
