Sensitivity of offset and onset cortical auditory evoked potentials to signals in noise

Highlights • The cortical auditory evoked offset response shows sensitivity to signal level changes in noise, whereas the cortical auditory evoked onset response does not. • The N2 wave in the offset response was particularly pronounced, and was the clearest indicator of offset response magnitude. •...

More Information
Summary:Highlights • The cortical auditory evoked offset response shows sensitivity to signal level changes in noise, whereas the cortical auditory evoked onset response does not. • The N2 wave in the offset response was particularly pronounced, and was the clearest indicator of offset response magnitude. • Rectified area amplitudes computed over the range of the offset response captured the same main effects as peak measures.
