“…The lowest f 0 of 80-100Hz corresponds to what has been reported in the literature (Green, 1975;Grimm, 1967;Lillehei and Snowdon, 1978;Hohmann and Herzog, 1985;Hauser, 1991;Hauser and Fowler, 1992;Owren et al, 1992;Owren and Rendall, 2003;Patel and Owren, 2007). The estimated maximum f 0 of ~2kHz fits many harmonic call types reported for rhesus monkeys, such as coo calls (Rowell and Hinde, 1962;Hauser, 1991;Owren and Rendall, 2003) or the girney call (Rowell and Hinde, 1962;Hauser and Fowler, 1992). But the highest ever reported f 0 is close to 8kHz for screams and squeaks (e.g.…”

SUMMARYFundamental frequency is an important perceptual parameter for acoustic communication in mammals. It is determined by vocal fold oscillation, which depends on the morphology and viscoelastic properties of the oscillating tissue. In this study, I tested if stress-strain and stress-relaxation behavior of rhesus monkey (Macaca mulatta) vocal folds allows the prediction of a species' natural fundamental frequency range across its entire vocal repertoire as well as of frequency contours within a single call type. In tensile tests, the load-strain and stress-relaxation behavior of rhesus monkey vocal folds and ventricular folds has been examined. Using the string model, predictions about the species' fundamental frequency range, individual variability, as well as the frequency contour of 'coo' calls were made. The low-and mid-frequency range (up to 2kHz) of rhesus monkeys can be predicted relatively well with the string model. The discrepancy between predicted maximum fundamental frequency and what has been recorded in rhesus monkeys is currently ascribed to the difficulty in predicting the behavior of the lamina propria at very high strain. Histological sections of the vocal fold and different staining techniques identified collagen, elastin, hyaluronan and, surprisingly, fat cells as components of the lamina propria. The distribution of all four components is not uniform, suggesting that different aspects of the lamina propria are drawn into oscillation depending on vocal fold tension. A differentiated recruitment of tissue into oscillation could extend the frequency range specifically at the upper end of the frequency scale.

“…Rhesus monkeys use coo vocalizations to identify and reconnect with their family and social group members (Hauser, 1991; Pfefferle, Ruiz-Lambides, & Widdig, 2014; Rowell & Hinde, 1962), but coo frequency is known to decrease in the human intruder task as the animals mature (Kalin & Shelton, 1998). A similar trend in coo vocalization was seen in the control animals of this study, whereas animals with Neo-PRh lesions maintained a high frequency of coo vocalizations even in adulthood.…”

The medial temporal lobe (MTL) is a collection of brain regions best known for their role in perception, memory, and emotional behavior. Within the MTL, the perirhinal cortex (PRh) plays a critical role in perceptual representation and recognition memory, although its contribution to emotional regulation is still debated. Here, rhesus monkeys with neonatal perirhinal lesions (Neo-PRh) and controls (Neo-C) were tested on the Human Intruder (HI) task at 2 months, 4.5 months, and 5 years of age, to assess the role of the PRh in the development of emotional behaviors. The HI task presents a tiered social threat to which typically developing animals modulate their emotional responses according to the level of threat. Unlike animals with neonatal amygdala or hippocampal lesions, Neo-PRh animals were not broadly hyper- or hypo-responsive to the threat presented by the HI task as compared to controls. Instead, Neo-PRh animals displayed an impaired ability to modulate their freezing and anxiety-like behavioral responses according to the varying levels of threat. Impaired transmission of perceptual representation generated by the PRh to the amygdala and hippocampus may explain the animals’ inability to appropriately assess and react to complex social stimuli. Neo-PRh animals also displayed fewer hostile behaviors in infancy and more coo vocalizations in adulthood. Neither stress reactive nor basal cortisol levels were affected by the Neo-PRh lesions. Overall, these results suggest that the PRh is indirectly involved in the expression of emotional behavior, and that effects of Neo-PRh lesions are dissociable from neonatal lesions to other temporal lobe structures.

“…Gecker vocalizations were identified based on previous annotations in the database ͑Owren et al, 1992a͒, by matching acoustic features to published descriptions of gecker calls ͑e.g., Rowell and Hinde 1962;Jovanovic and Gouzoules 2001͒, and by ear. A total of 111 analyzable gecker bouts comprising 651 individual gecker pulses from the ten vocalizers were identified in this manner ͑see Table I͒.…”

Acoustics and behavioral contexts of “gecker” vocalizations in young rhesus macaques (Macaca mulatta)

Loud, pulsed "gecker" vocalizations are commonly produced by young rhesus macaques in distressful circumstances. The acoustics, usage, and responses associated with these calls were examined using audio recordings and observational data from captive, socially living rhesus up to 24 months old. One-hundred-eleven gecker bouts were recorded from ten individuals (six males, four females), with most geckers produced during the first 6 months of age. A gecker call consisted of a bout of up to 28 pulses of spectrally structured noise with a single prominent frequency peak. Nine contexts of calling were identified, but little evidence of context-specific acoustic variation was found. While geckering often triggered responses by the vocalizer's mother, the most common outcome was the absence of any reaction. Females geckered longer and at higher rates than did males, while also showing acoustic evidence of greater vocal effort. Mothers nonetheless responded more often and more positively to males. Overall, results show that gecker acoustics vary somewhat with vocalizer sex, age, and likely arousal level, but do not reflect detailed aspects of behavioral context. Circumstances of production suggest that geckers function primarily to draw the attention of mothers, who in turn are selective in responding.
