It has often been proposed that the vocal calls of monkeys are precursors of human speech, in part because they provide critical information to other members of the species who rely on them for survival and social interactions. Both behavioural and lesion studies suggest that monkeys, like humans, use the auditory system of the left hemisphere preferentially to process vocalizations. To investigate the pattern of neural activity that might underlie this particular form of functional asymmetry… 
A voice region in the monkey brain
Using functional magnetic resonance imaging of macaque monkeys, a high-level auditory region is discovered that prefers species-specific vocalizations over other vocalizations and sounds and supports the notion that, for different primate species, the anterior temporal regions of the brain are adapted for recognizing communication signals from conspecifics.
Interhemispheric differences in auditory processing revealed by fMRI in awake rhesus monkeys.
Lesion studies in monkeys have suggested a modest left hemisphere dominance for processing species-specific vocalizations, the neural basis of which has thus far remained unclear. We used contrast
Species-specific calls activate homologs of Broca's and Wernicke's areas in the macaque
Neural systems associated with perceiving species-specific vocalizations in rhesus macaques using H215O positron emission tomography are identified and this finding suggests the possibility that the last common ancestor of macaques and humans possessed key neural mechanisms that were plausible candidates for exaptation during the evolution of language.
Visualizing vocal perception in the chimpanzee brain.
P positron emission tomography is used to examine the neurological mechanisms associated with the perception of species-specific vocalizations in chimpanzees and provides the first evidence of the neural correlates of auditory perception in chimpanzees.
Hemispheric Specialization in Dogs for Processing Different Acoustic Stimuli
Investigating whether dogs use different hemispheres to process different acoustic stimuli by presenting them with playbacks of a thunderstorm and their species-typical vocalizations suggested that the specialisation of the left hemisphere for intraspecific communication is more ancient that previously thought.
Acoustic features of rhesus vocalizations and their representation in the ventrolateral prefrontal cortex.
The hypothesis that the ventrolateral prefrontal cortex is not involved in coding the first-order acoustic properties of a stimulus but is involved in processing the higher-order information needed to form representations of auditory objects is consistent with the hypothesis.
Is voice processing species-specific in human auditory cortex? An fMRI study
Common principles in the lateralization of auditory cortex structure and function for vocal communication in primates and rodents
It is argued that a synthesis of results from humans, non‐human primates and rodents is necessary to identify the neural circuitry of vocal communication processing, and efforts to standardize data formats and analysis tools would benefit comparative research and enable synergies between psychological and biological research in the area of vocal Communication processing.
Sex-dependent hemispheric asymmetries for processing frequency-modulated sounds in the primary auditory cortex of the mustached bat.
The results demonstrate a left hemispheric bias in males for the representation of a diverse array of FMs differing in rate and bandwidth, and propose that these asymmetries underlie lateralized processing of communication sounds and are common to species as divergent as bats and humans.


Differential representation of species-specific primate vocalizations in the auditory cortices of marmoset and cat.
Differential representation of marmoset vocalizations in two cortices suggests that experience-dependent and possibly species-specific mechanisms are involved in cortical processing of communication sounds.

Like humans, adult rhesus monkeys also evidence left hemisphere dominance for processing species-specific vocalizations, however, the emergence of such asymmetry may depend on both differential maturation of the two hemispheres and experience with the species-typical vocal repertoire.
Mechanisms and streams for processing of "what" and "where" in auditory cortex.

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.
Neural lateralization of species-specific vocalizations by Japanese macaques (Macaca fuscata).
The results suggest that Japanese macaques engage left-hemisphere processors for the analysis of communicatively significant sounds that are analogous to the lateralized mechanisms used by humans listening to speech.
Left hemisphere advantage in the mouse brain for recognizing ultrasonic communication calls
In the house mouse, which has a very much less elaborate forebrain than man or macaque monkey, the ultrasonic calls that are emitted by young mice to evoke maternal caring behaviour are preferentially recognized by the left hemisphere, suggesting that lateralization of this function evolved early in mammals.
Temporal lobe lesions and perception of species-specific vocalizations by macaques.
The perception of species-specific vocalizations by Japanese macaques seems to be mediated by the temporal cortex, with the left hemisphere playing a predominant role.
Functional Mapping of the Primate Auditory System
Several auditory areas overlapped with previously identified visual areas, suggesting that the auditory system, like the visual system, contains separate pathways for processing stimulus quality, location, and motion.
Discrete or graded variation within rhesus monkey screams? Psychophysical experiments on classification
This result suggests that rhesus monkeys do not perceive categorical distinctions between arched and tonal screams, at least under the testing conditions implemented, and provides evidence for a graded category.
