2019 Nature Reviews Neuroscience  
This cortical network accommodates changing behavioural requirements and is especially relevant for processing the location of real-life, complex sounds and complex auditory scenes.  ...  We propose that the cortical representation of sound location emerges from recurrent processing taking place in a dynamic, adaptive network of early (primary) and higher-order (posterior-dorsal and dorsolateral  ...  Arrow 2 reflects an indirect feedback route in which top-down modulations of PAC activity by dlPFC are mediated by planum temporale (PT), the area that is traditionally implicated in spatial processing  ...
