Abstract
A particularly prominent model of auditory cortical function proposes that a dorsal brain pathway, emanating from the posterior auditory cortex, is primarily concerned with processing the spatial features of sounds. In the present paper, we outline some difficulties with a strict functional interpretation of this pathway, and highlight the recent trend to understand this pathway in terms of one that uses acoustic information to guide motor output towards objects of interest. In this spirit, we consider the possibility that some of the auditory spatial processing activity that has been observed in the dorsal pathway may actually be understood as a form of action processing in which the visual system may be guided to a particular location of interest. In this regard, attentional orientation may be considered a low-level form of action planning. Incorporating an auditory-guided motor aspect to the dorsal pathway not only offers a more holistic account of auditory processing, but also provides a more ecologically valid perspective on auditory processing in dorsal brain regions.
