“…Anatomically, the vPFC is located anterior to the arcuate sulcus and area 8a, and it lies below the principal sulcus (Romanski & Goldman-Rakic 2002). The recording sites were similar to those reported in previous studies from our laboratory (Cohen et al 2004;. All surgical procedures and protocols were approved by Dartmouth College's Institutional Animal Care and Use Committee and were in accordance with the United States of America's guidelines for the care and use of animals in research.…”

“…These non-food SSVs transmit information different from that of the food SSVs. Since the monkeys in this study had considerable experience with both the food and non-food SSVs (Cohen et al 2004;Russ et al 2005), any potential difference in neural activity in response to the food and non-food SSVs cannot be attributed solely to differences in familiarity (Humphrey & Keeble 1976).…”

Spontaneous processing of abstract categorical information in the ventrolateral prefrontal cortex

In various aspects of linguistic analysis and human cognition, some forms of observed variation are ignored in the service of handling more abstract categories. In the absence of training, rhesus discriminate between different types of vocalizations based on the information conveyed as opposed to their acoustic morphologies. We hypothesized that neurons in the ventrolateral prefrontal cortex (vPFC), an area involved in auditory-object processing, might be involved in this spontaneous categorization. To test this hypothesis, we recorded vPFC activity while rhesus listened to vocalizations conveying information about food and non-food events. Results showed between, but not within category discrimination. That is, vPFC neurons discriminated between vocalizations associated with food versus non-food events but not within the class of food calls associated with differences in quality. These results indicate that the vPFC plays a significant role in spontaneously processing abstract categorical information.

tion is one of the fundamental components of both human and nonhuman animal behavior. Auditory communication signals (i.e., vocalizations) are especially important in the socioecology of several species of nonhuman primates such as rhesus monkeys. In rhesus, the ventrolateral prefrontal cortex (vPFC) is thought to be part of a circuit involved in representing vocalizations and other auditory objects. To further our understanding of the role of the vPFC in processing vocalizations, we characterized the spectrotemporal features of rhesus vocalizations, compared these features with other classes of natural stimuli, and then related the rhesus-vocalization acoustic features to neural activity. We found that the range of these spectrotemporal features was similar to that found in other ensembles of natural stimuli, including human speech, and identified the subspace of these features that would be particularly informative to discriminate between different vocalizations. In a first neural study, however, we found that the tuning properties of vPFC neurons did not emphasize these particularly informative spectrotemporal features. In a second neural study, we found that a first-order linear model (the spectrotemporal receptive field) is not a good predictor of vPFC activity. The results of these two neural studies are consistent with the hypothesis that the vPFC is not involved in coding the first-order acoustic properties of a stimulus but is involved in processing the higher-order information needed to form representations of auditory objects. I N T R O D U C T I O NCommunication is one of the fundamental components of both human and nonhuman animal behavior (Hauser 1997). Although the benefits and importance of language in human evolution are obvious (Carruthers 2002;Hauser 1997;Lieberman 2002), other nonhuman communication systems are also important. These communication systems are important because for most, if not all, species they are critical to the species' survival (Andersson 1996;Bennett et al. 1997;Greenfield 2002;Hauser 1997;Lau et al. 2000;Mech and Boitani 2003).For example, auditory communication signals (i.e., speciesspecific vocalizations) are especially important in the socioecology of several species of nonhuman primates (Cheney and Seyfarth 1985;Eimas 1994;Eimas et al. 1971;Hauser 1997;Jusczyk 1997;Jusczyk et al. 1983; Miller and Eimas 1995), such as rhesus monkeys (Macaca mulatta). Vocalizations convey information about the identity and the age of the caller and often provide information about sex and emotional or motivational state (Cheney and Seyfarth 1990; Hauser 1997). Some vocalizations transmit information about objects and events in the environment (Gifford 3rd et al. 2003;Hauser 1998;Seyfarth and Cheney 2003).In rhesus monkeys, the ventrolateral prefrontal cortex (vPFC) plays an important role in processing vocalizations (Hackett et al. 1999;Romanski and Goldman-Rakic 2002;Romanski et al. 1999 Romanski et al. , 2005.

“…He observed no significant difference in the overall firing rate of neurons between these different cortical areas, thus disputing the claim that the early rostral cortical areas are preferentially involved in the selective processing of vocalizations. However, with the exception of a few studies (Cohen et al, 2004), electrophysiological evidence of selectivity to species-species vocalizations outside the auditory cortical areas is lacking.…”
