The existence of a specialized human cortical area for the processing of auditory motion is still a matter of debate. Initial functional imaging studies identified the planum temporale as being motion selective. Recent data contrasting spatially varying stationary stimuli with moving stimuli found no difference in the amount of activation between the two types of stimuli in the planum temporale. The present study re-examines this issue using an event-related paradigm. Ten subjects were scanned while listening to pairs of stimuli that were either both moving or both stationary. Consistent with the aforementioned study, we found no difference in the activation levels in the planum temporale when comparing motion and stationary conditions.
是否存在一个专门用于处理听觉运动的人类皮质区域仍是一个有争议的问题。最初的功能成像研究确定颞平面具有运动选择性。最近的数据将空间变化的静止刺激与移动刺激进行对比,发现在颞平面中这两种类型的刺激之间的激活量没有差异差异。本研究使用事件相关范式重新审视了这个问题。十名受试者在听成对的刺激时接受扫描,这些刺激要么都是移动的,要么都是静止的。与上述研究一致,我们发现在比较运动和静止条件时,颞平面的激活水平没有差异。
