For vocal animals, recognizing species-specific vocalizations is important for survival and social interactions. In humans, a voice region has been identified that is sensitive to human voices and vocalizations. As this region also strongly responds to speech, it is unclear whether it is tightly associated with linguistic processing and is thus unique to humans. Using functional magnetic resonance imaging of macaque monkeys (Old World primates, Macaca mulatta) we discovered a high-level… 

Functionally homologous representation of vocalizations in the auditory cortex of humans and macaques

Humans Mimicking Animals: A Cortical Hierarchy for Human Vocal Communication Sounds

The results suggest that the cortical regions supporting vocalization perception are initially organized by sensitivity to the human vocal tract in stages in stages before the superior temporal sulcus (STS).

Human temporal voice areas are sensitive to chimpanzee vocalizations

The results provide evidence for a common neural basis in the TVA for the processing of phylogenetically and acoustically close vocalizations, namely those of humans and chimpanzees.

Functional MRI of the vocalization-processing network in the macaque brain

It is demonstrated that species-specific vocalizations in rhesus monkeys activate preferentially the auditory ventral stream, and in particular areas of the antero-lateral belt and parabelt.

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.

Voice Cells in the Primate Temporal Lobe

The primate cortical auditory system and neural representation of conspecific vocalizations.

The discovery that several nonprimary auditory cortical regions may be multisensory and responsive to vocalizations with corresponding facial gestures may change the way in which the authors view the processing of communication information by the auditory system.



Species-specific calls evoke asymmetric activity in the monkey's temporal poles

To investigate the pattern of neural activity that might underlie this particular form of functional asymmetry in monkeys, local cerebral metabolic activity was measured while the animals listened passively to species-specific calls compared with a variety of other classes of sound.

Is voice processing species-specific in human auditory cortex? An fMRI study

This comparative review focuses on behavioural and neurobiological evidence relative to two issues central to voice perception in human and non-human primates: are CVs ‘special’, i.e. are they analysed using dedicated cerebral mechanisms not used for other sound categories, and to what extent and using what neural mechanisms do primates identify conspecific individuals from their vocalizations.

Human temporal-lobe response to vocal sounds.

Multisensory Integration of Dynamic Faces and Voices in Rhesus Monkey Auditory Cortex

It is demonstrated unequivocally that the primate auditory cortex integrates facial and vocal signals through enhancement and suppression of field potentials in both the core and lateral belt regions of the auditory cortex in awake behaving rhesus monkeys.

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.

Identification of a pathway for intelligible speech in the left temporal lobe.

It is demonstrated that the left superior temporal sulcus responds to the presence of phonetic information, but its anterior part only responds if the stimulus is also intelligible, demonstrating a left anterior temporal pathway for speech comprehension.

Selectivity for animal vocalizations in the human auditory cortex.

The data suggest that complex sounds such as animal vocalizations are represented in putatively nonprimary auditory cortex in the left STG, probably based on their spectrotemporal dynamics rather than simple spectral features.

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.
