Maps and streams in the auditory cortex: nonhuman primates illuminate human speech processing
This paper will demonstrate how the understanding of speech perception, one important facet of language, has profited from findings and theory in nonhuman primate studies, and identify roles for different cortical areas in the perceptual processing of speech.

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.

Injection of multiple tracers into physiologically mapped regions AL, ML and CL of the auditory belt cortex revealed that anterior belt cortex was reciprocally connected with the frontal pole, rostral principal sulcus and ventral prefrontal regions.
Processing of complex sounds in the macaque nonprimary auditory cortex.
The lateral areas of the monkey auditory cortex appear to be part of a hierarchical sequence in which neurons prefer increasingly complex stimuli and may form an important stage in the preprocessing of communication sounds.
Functional Specialization in Rhesus Monkey Auditory Cortex
The results suggest that cortical processing of auditory spatial and pattern information is performed in specialized streams rather than one homogeneously distributed system.

A Positron Emission Tomographic Study of Auditory Localization in the Congenitally Blind
The blind subjects demonstrated visual to auditory cross-modal plasticity with auditory localization activating occipital association areas originally intended for dorsal-stream visual processing as well as demonstrating functional connectivity of pre-selected brain regions in primary and non-primary auditory and posterior parietal cortex.

Modality-specific frontal and parietal areas for auditory and visual spatial localization in humans
Using positron emission tomography during auditory and visual spatial localization in the same subjects, modality-specific areas were identified in the superior parietal lobule, middle temporal and lateral prefrontal cortices that suggest the hierarchical organization of the auditory system extends beyond the temporal lobe.

The hypothesis is put forward that the central auditory pathways in the macaque monkey are organized into parallel streams, similar to the visual system, one for the processing of spatial information, the other for theprocessing of auditory ‘patterns’.
