FMRI correlates of the auditory 40-Hz steady-state response

The auditory 40-Hz steady-state response (SSR) is a stimulus-synchronized component of the auditory evoked fields and potentials. Source analysis studies suggest that the SSR shares its main generators in the primary auditory cortex with the middle latency response, and subcortical generators with the brainstem response. In this study, we adopted a paradigm previously used in positron emission tomography (PET) (Reyes et al, 2004, Hear. Res. 194(1–2):73–80) to evaluate functional magnetic resonance imaging (fMRI) correlates of the SSR, and compare these results with the SSR recorded in Magnetoencephalography (MEG…
