High-resolution fMRI reveals a dorsal brain pathway selective for conspecific vocalizations in macaques.

ABSTRACT: Understanding the neural basis of social communication and vocal perception in primates is a key challenge in systems neuroscience. Vocalizations are fundamental for communication, and several cortical areas, known as "voice patches," have been identified as being sensitive to conspecific vocalizations in primates, vital for distinguishing species-specific calls. While the dorsal stream's role in complex auditory-motor functions and human speech processing is established, its specific contribution to processing species-specific vocalizations in non-human primates remains unclear. Using high-resolution fMRI (0.6 mm isotropic voxels), we investigated brain regions involved in processing vocalizations in awake rhesus monkeys exposed to coos, screams, and aggressive calls, among control sounds
