Auditory Spatial and Object Processing in the Human Planum Temporale: No Evidence for Selectivity
It is suggested that previously documented spatial sensitivity in the PT reflects auditory source separation using spatial cues rather than spatial processing per se.
The Contribution of the Inferior Parietal Lobe to Auditory Spatial Working Memory
Dual roles for the right IPL in auditory working memory are suggested, one involved in monitoring and updating sound location independent of motor responding, and another that underlies the integration of sensory and motor functions.
Frequency-dependent auditory space representation in the human planum temporale
Results show that spatially tuned neurons in the human PT are not invariant to the spectral content of sounds, as required from high order sensory representations.
Psychophysics and neuronal bases of sound localization in humans
Processing of sound location in human cortex
The finding of activations also in the ventral stream could reflect the well‐known functional duality of auditory spectral analysis, that is, the concurrent extraction of information based on location and spectral characteristics of a sound source, and suggest the existence of shared neural networks.
Activity associated with stream segregation in human auditory cortex is similar for spatial and pitch cues.
Streaming is a perceptual mechanism by which the brain segregates information from multiple sound sources in our environment and assigns them to distinct auditory streams. Examples for streaming cues
Functionally distinct regions for spatial processing and sensory motor integration in the planum temporale
Findings support a heterogeneous model of the PT, with functionally distinct regions for sensory‐motor integration and processes involved in auditory spatial perception.


“What” and “where” in the human auditory system
The converging evidence from two independent measurements of dissociable brain activity during identification and localization of identical stimuli provides strong support for specialized auditory streams in the human brain.
Evidence for Dissociation of Spatial and Nonspatial Auditory Information Processing
Latency and amplitude task-related differences in the N1/N1m components as well as the source location differences indicate at least partial segregation of neuronal mechanisms involved in working memory processing of spatial and nonspatial auditory information.
Where is 'where' in the human auditory cortex?
It is found that the right inferior parietal cortex is specifically recruited in localization tasks, and that its activity predicts behavioral performance, consistent with its involvement in sensorimotor integration and spatial transformation.
Distinct Pathways Involved in Sound Recognition and Localization: A Human fMRI Study
Evidence from psychophysical studies in normal and brain-damaged subjects suggests that auditory information relevant to recognition and localization are processed by distinct neuronal populations.

The cortical auditory system of primates is divided into at least two processing streams, a spatial stream that originates in the caudal part of the superior temporal gyrus and projects to the parietal cortex, and a pattern or object stream originating in the more anterior portions of the lateral belt.
Cortical representations of temporal structure in sound.
The results of a systematic test for whether different classes of temporal structure do indeed engage a common neural architecture in the human auditory cortex by presenting both classes of sound stimuli to a single group of listeners show that the activity in lateral HG is consistent with a role for lateral HG in perceptual analysis as opposed to temporal acoustic structure.
Detection of Audio-Visual Integration Sites in Humans by Application of Electrophysiological Criteria to the BOLD Effect
The efficacy of using an analytic approach informed by electrophysiology to identify multisensory integration sites in humans is demonstrated and the particular network of brain areas implicated in these crossmodal integrative processes are suggested to be dependent on the nature of the correspondence between the different sensory inputs.
Selectivity for the Spatial and Nonspatial Attributes of Auditory Stimuli in the Ventrolateral Prefrontal Cortex
It is found that vPFC neurons were modulated significantly by both the spatial and nonspatial attributes of an auditory stimulus, and the spatial selectivity was better than anterolateral neurons.
