Abstract:Stimulusrate will affect some components of AEPs, typically Pbfor instance, which demonstrates an unstable characteristic in terms of elicitation at different stimulus rates. In practice, increasing stimulus rate has to be restricted to prevent the AEPs from overlapping. Two newly developed deconvolution techniques, so called continuous loop averaging deconvolution (CLAD) and multirate steadystate averaging deconvolution (MSAD) have been proposed to retrieve high rate AEP. As the computational theory and experimental paradigm are different for the two methods, it is thus in need of adequate experimental evaluation for high rate AEPs. This study investigated the elicitation of the deconvolved AEPs at 40 Hz sampled from eleven healthy adults in comparison with the conventional AEP at 5 Hz. Results show that the main components of 40 Hz transient AEPs can be fully elicited, while the elicitation rate for conventional AEPs is 72.73% for Nb, and 54.55% for Pb; likewise the comparison with mean variable coefficient is 6.57% vs. 11.18%, and the correlation coefficient is 0.87 vs 0.70. These results indicate the promising application of the two deconvolution techniques, and suggest that the main components of 40 Hz transient AEPs can be of substantial advantage over the conventional one.
