There is debate about the nature of the dorsal 听觉 processing 流. Some folks, Josef Rauschecker in particular, argue for a dorsal "哪里" 流, 哪里as others, Hickok & Poeppel and Warren et al., argue for a 感官-motor integration (sometimes called "how") 流. Here's why the "哪里" hypothesis can't, in principle, be right.
Spatial information associated with an 听觉 signal is a stimulus 特征 much like pitch. We don't talk about a "pitch 流" however. 为什么not? Because pitch (frequency) is just a cue for any number of processing goals. Pitch information can cue phonemic identity, speaker voice, 听觉 流 segregation ... even 感官-motor goals (humming back a tone). Spatial cues are no different in that they can cue explicit location judgments, 听觉 流 segregation, and any number of 感官-motor processes (head movements, saccades, locomotion toward or away from a source).
Processing 流s, I'm suggesting, are defined by goals or tasks -- 什么 the information is used for -- not by stimulus 特征s. Sensory-motor integration for vocal tract actions defines a goal -- control of the vocal tract -- and therefore is a viable candidate for a processing 流. Identifying the meaning of an 听觉 object is also a goal and a good candidate for a processing 流. Stimulus 特征s, like pitch or location are not goals, they are just cues that can be used within various task-driven processing 流s.
Of course, this doesn't imply that there isn't a specialized location processing system in the brain that uses interaural time and level differences to compute 空间的 information. Almost for sure there is (my guess is that it's subcortical), just like there is a system that processes pitch using frequency information. But we shouldn't confuse a specialized 特征 processing system (area) with a cortical processing 流 as the notion "流" is typically used.
Which reminds me. It is probably time to redefine the notion of a processing "流"。一世n particular, I think the dorsal-ventral distinction is getting tired and has now outlived its usefulness. I'll expand in a later post...
