“…When this region is electrically stimulated, movements of the vocal chords are triggered in human and non-human primates [Jurgens, 2002;Penfield and Rasmussen, 1952]. Furthermore, if it is damaged bilaterally in humans, singing and speaking is no longer possible [Groswasser et al, 1988]. In squirrel monkeys, it has been shown to be a part of the motorcortical pathway, which controls the patterning of learned vocal utterances via the reticular formation [Jurgens, 2009].…”

Listening to music can induce us to tune in to its beat. Previous neuroimaging studies have shown that the motor system becomes involved in perceptual rhythm and timing tasks in general, as well as during preference-related responses to music. However, the role of preferred rhythm and, in particular, of preferred beat frequency (tempo) in driving activity in the motor system remains unknown. The goals of the present functional magnetic resonance imaging (fMRI) study were to determine whether the musical rhythms that are subjectively judged as beautiful boost activity in motor-related areas and if so, whether this effect is driven by preferred tempo, the underlying pulse people tune in to. On the basis of the subjects' judgments, individual preferences were determined for the different systematically varied constituents of the musical rhythms. Results demonstrate the involvement of premotor and cerebellar areas during preferred compared to not preferred musical rhythms and indicate that activity in the ventral premotor cortex (PMv) is enhanced by preferred tempo. Our findings support the assumption that the premotor activity increase during preferred tempo is the result of enhanced sensorimotor simulation of the beat frequency. This may serve as a mechanism that facilitates the tuning-in to the beat of appealing music.

“…Bilateral lesion of the region of orofacial representation in primary motor and premotor cortex, for example, does not significantly alter the acoustic structure of calls or the rate of calling in squirrel monkeys Kirzinger and Jürgens, 1982] or macaques [Myers, 1969;Sutton et al, 1974;Aitken, 1981]. In contrast, the primary motor cortex is activated during speech and singing in humans [Salmelin and Sams, 2002] and bilateral destruction of the primary motor cortex in humans causes pseudobulbar palsy, a syndrome characterized by complete loss of voluntary control of linguistic phonation, with sparing of emotional utterances such as groaning, crying, and laughing [Alajouanine and Thurel, 1933;Foerster, 1936;Mariani et al, 1980;Groswasser et al, 1988;Mao et al, 1989]. Thus, interspecific differences in the execution of voluntary orofacial movements, such as non-emotional facial expressions and speech in humans, may be subserved by phylogenetic diversification in the structure and connections of the primary motor cortex.…”

Cortical Orofacial Motor Representation in Old World Monkeys, Great Apes, and Humans

Social life in anthropoid primates is mediated by interindividual communication, involving movements of the orofacial muscles for the production of vocalization and gestural expression. Although phylogenetic diversity has been reported in the auditory and visual communication systems of primates, little is known about the comparative neuroanatomy that subserves orofacial movement. The current study reports results from quantitative image analysis of the region corresponding to orofacial representation of primary motor cortex (Brodmann’s area 4) in several catarrhine primate species (Macaca fascicularis, Papio anubis, Pongo pygmaeus, Gorilla gorilla, Pan troglodytes, and Homo sapiens) using the Grey Level Index method. This cortical region has been implicated in the execution of skilled motor activities such as voluntary facial expression and human speech. Density profiles of the laminar distribution of Nissl-stained neuronal somata were acquired from high-resolution images to quantify cytoarchitectural patterns. Despite general similarity in these profiles across catarrhines, multivariate analysis showed that cytoarchitectural patterns of individuals were more similar within-species versus between-species. Compared to Old World monkeys, the orofacial representation of area 4 in great apes and humans was characterized by an increased relative thickness of layer III and overall lower cell volume densities, providing more neuropil space for interconnections. These phylogenetic differences in microstructure might provide an anatomical substrate for the evolution of greater volitional fine motor control of facial expressions in great apes and humans.

“…Additionally, the results of lesioning studies in the context of animal vocalizations have been criticized (Ghazanfar and Rendall, 2008). For instance, one major finding of this research in a comparative framework has been that introducing lesions or electrically stimulating primate cortical areas thought to be involved in vocalization has had little effect (Aitken, 1981;Jürgens et al, 1982), as compared with humans who are heavily impaired when Broca or Wernicke's areas are damaged (Groswasser et al, 1988;Mariani et al, 1980). However, these results may benefit from a newer and more informed appraisal based on current knowledge of the primate vocal system (Ghazanfar and Rendall, 2008).…”

“…Some of them undoubtedly are (Tomasello, 2008), but so are some equally uncontrollable human vocalizations such as screaming, groaning, crying, or laughing (Groswasser et al, 1988;Mariani et al, 1980). However, primates may also have more control over intentional calls (calls that are produced with the aim of fulfilling a goal) or referential calls (calls that indicate something to someone), which both fulfill a complementary communicative role to the conveying of emotions (Crockford et al, 2012;Liebal et al, 2014;Sievers and Gruber, 2016); finally some calls may have a learnt component (e.g.…”

a b s t r a c tDifferent approaches from different research domains have crystallized debate over primate emotional processing and vocalizations in recent decades. On one side, researchers disagree about whether emotional states or processes in animals truly compare to those in humans. On the other, a long-held assumption is that primate vocalizations are innate communicative signals over which nonhuman primates have limited control and a mirror of the emotional state of the individuals producing them, despite growing evidence of intentional production for some vocalizations. Our goal is to connect both sides of the discussion in deciphering how the emotional content of primate calls compares with emotional vocal signals in humans. We focus particularly on neural bases of primate emotions and vocalizations to identify cerebral structures underlying emotion, vocal production, and comprehension in primates, and discuss whether particular structures or neuronal networks solely evolved for specific functions in the human brain. Finally, we propose a model to classify emotional vocalizations in primates according to four dimensions (learning, control, emotional, meaning) to allow comparing calls across species.
