Abstract
Both PET-independent and PET-weighted LORETA results suggest that the aSSR is: (1) the result of a reverberating network with two or more groups of sources that recurrently excite each other or (2) the result of sequential auditory processing through various levels of a hierarchical network. In contrast, the PET-weighted MinNorm results suggest that the 40-Hz response represents simultaneous activation over widely spaced areas of the brain, perhaps due to synchronization of γ-band activity to a common neural clock.
