This work examined the mechanisms underlying auditory motion processing in the auditorycortex of awake monkeys using functional magnetic resonance imaging (fMRI). We testedto what extent auditory motion analysis can be explained by the linear combination of staticspatial mechanisms, spectrotemporal processes, and their interaction. We found that theposterior auditory cortex, including A1 and the surrounding caudal belt and parabelt, isinvolved in auditory motion analysis. Static spatial and spectrotemporal processes wereable to fully explain motion-induced activation in most parts of the auditory cortex, includingA1, but not in circumscribed regions of the posterior belt and parabelt cortex. We show thatin these regions motion-specific processes contribute to the activation, providing the firstdemonstration that auditory motion is not simply deduced from changes in static spatiallocation. These results demonstrate that parallel mechanisms for motion and static spatialanalysis coexist within the auditory dorsal stream.
