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