Systematic latency variation of the auditory evoked M100: from average to single-trial data
2004
NeuroImage
Preserved Fulltext
Specifically, the latency of the auditory evoked M100 varies systematically with stimulus frequency over a well-defined time range (lower frequencies, e.g., 125 Hz, yield up to 25 ms longer latencies than ...
Can such critical timing properties of event-related responses be recovered from single-trial data? ...
