Responses exceeding two standard deviations (P < 0.05) of the baseline noise at any magnetometer channel or twice the baseline amplitude of the global root‐mean‐square signal. Magnetic ABRs are labeled according to the simultaneously recorded electric responses. Roman numerals refer to the standard labeling with the minus sign denoting the trough following the peak; N and P denote vertex‐negative and ‐positive (respectively) EEG‐counterpart of the response, followed by an approximate latency in milliseconds.
