Topic: voice patches

Social interactions play a major role in primates. They rely in part on our ability to extract relevant information from the voices of our conspecifics. fMRI studies have highlighted Temporal Voice Areas or ‘voice patches’ in the brain of humans, macaques and marmosets : these regions of cortex selectively respond to conspecific vocalizations, but little is known about how individual voice patch neurons encode vocal information, particularly on caller identity. The ‘Norm-based coding’ hypothesis from face perception research suggests that neuronal activity could be modulated by the acoustical

Understanding the neural underpinnings of social communication and emotional processing in non-human primates remains a significant challenge in neuroscience. In primates, studies using neuroimaging techniques such as fMRI, and electrophysiological recordings have identified several voice-sensitive cortical areas, i.e., the so-called voice patches. These voice patches are believed to be crucial for processing and distinguishing various vocalizations made by individuals of the same species (see for review Belin et al. 2018; and Bondin et al. 2021). In this study, we used fMRI (0.6 isotropic vox
