The goal of the present study was to determine whether the architectonic criteria used to identify the core, lateral belt, and parabelt auditory cortices in macaque monkeys (Macaca fascicularis) could be used to identify homologous regions in humans (Homo sapiens). Current evidence indicates that auditory cortex in humans, as in monkeys, is located on the superior temporal gyrus (STG), and is functionally and structurally altered in illnesses such as schizophrenia and Alzheimer's disease.

Architectonic analysis of the auditory‐related areas of the superior temporal region in human brain
Architecture of auditory areas of the superior temporal region (STR) in the human was analyzed in Nissl‐stained material to see whether auditory cortex is organized according to principles that have
Functional Correlates of the Anterolateral Processing Hierarchy in Human Auditory Cortex
The results demonstrate that the functional organization of the anterolateral processing pathway in humans is largely consistent with that of nonhuman primates, and the approach of using identical schemes in both humans and monkeys will aid with establishing potential homologies between them.
Auditory Properties in the Parabelt Regions of the Superior Temporal Gyrus in the Awake Macaque Monkey: An Initial Survey
A new procedure for implanting recording chambers to provide direct access to the superior temporal gyrus is designed, allowing us to evaluate neuronal properties and their topography across the full extent of the STG in awake-behaving macaques.
Organization of auditory areas in the superior temporal gyrus of marmoset monkeys revealed by real-time optical imaging
The results suggest that the belt region caudoventral to R is more complex than previously proposed, and calls for a refinement of the current primate auditory cortex model.
3.3 Auditory Cortex Anatomy and Asymmetry in Schizophrenia
Initial findings suggest that early stages of auditory sensory processing, possibly including the primary auditory cortex, are involved in schizophrenia pathology, and these areas have anatomical changes comparable to those found in frontal and other regions of the cerebral cortex.
Functional connection between posterior superior temporal gyrus and ventrolateral prefrontal cortex in human.
A functional tract-tracing method was used in 12 neurosurgical patients with multicontact electrode arrays chronically implanted over the left or right perisylvian temporal auditory cortex and the ventrolateral prefrontal cortex for diagnosis and treatment of medically intractable epilepsy to provide evidence for a rapidly conducting pathway between area PLST and VLPFC.

From these efforts, common features of structural and functional organization have begun to emerge from which a working model of human auditory cortex can be derived.
Functional Topography of Auditory Areas Derived From the Combination of Electrophysiological Recordings and Cortical Electrical Stimulation
How the findings of this work help understanding the auditory semiology of certain epileptic seizures and, more generally, the neural substrate of hemispheric specialization for language are discussed are discussed.
Extensive Cochleotopic Mapping of Human Auditory Cortical Fields Obtained with Phase-Encoding fMRI
The primary sensory cortices are characterized by a topographical mapping of basic sensory features which is considered to deteriorate in higher-order areas in favor of complex sensory features.


Architectonic identification of the core region in auditory cortex of macaques, chimpanzees, and humans
Although the architectonic appearance of the core areas did vary in certain respects across taxonomic groups, the numerous similarities made it possible to identify unambiguously a homologous cortical region in macaques, chimpanzees, and humans.
Thalamocortical connections of the parabelt auditory cortex in macaque monkeys
The thalamocortical connections of the parabelt auditory cortex are described based on multiple injections of neuronal tracers into this region in each of five macaque monkeys, suggesting that this region represents a third level of auditory cortical processing, which is not influenced by direct inputs from primary cortical or subcortical auditory structures.
Auditory belt and parabelt projections to the prefrontal cortex in the Rhesus monkey
The present topographical results suggest that acoustic information diverges into separate streams that target distinct rostral and caudal domains of the prefrontal cortex, which may serve different acoustic functions.
Subdivisions of auditory cortex and ipsilateral cortical connections of the parabelt auditory cortex in macaque monkeys
Observations support the concept of dividing the auditory cortex into core, belt, and parabelt; provide evidence for including the rostral area in the core; suggest the existence of as many as seven or eight belt fields; provideevidence for at least two subdivisions of the parab belt; and identify regions of the temporal lobe involved in auditory processing.
Human Primary Auditory Cortex: Cytoarchitectonic Subdivisions and Mapping into a Spatial Reference System
In future, the transfer of in vivo structural and functional data into the same spatial reference system will enable accurate comparisons of cytoarchitectonic maps of the primary auditory cortex with activation centers as established with functional imaging procedures.

The challenge for future researchers is to understand how this complex system in monkeys analyzes and utilizes auditory information.
Polysensory properties of neurons in the anterior bank of the caudal superior temporal sulcus of the macaque monkey.
The sensory properties of cells in the anterior bank of the caudal part of the superior temporal sulcus (caudal STS) in anesthetized, paralyzed monkeys to visual, auditory, and somesthetic stimuli agreed with previous studies.
Women have greater density of neurons in posterior temporal cortex
The results suggest that the cortical functional unit has a different ratio of input and output components in men and women which could have implications for the sex differences in cognition and behavior.
