“…This proposed role is consistent with previous hypotheses regarding this region's role in the processing of acoustically meaningful communication signals (Deacon 1992;Jü rgens 2002). Since communication is often multimodal (Hinde & Rowell 1962;Hauser et al 1993;Partan & Marler 1999) and since vPFC neurons respond to visual stimuli (Romanski & Goldman-Rakic 2002), an interesting question to consider is whether this circuit represents auditory as well as visual communication signals and represents this information in a modalityindependent format (Ghazanfar & Logothetis 2003).…”

“…The vPFC was identified by its anatomical location and its neurophysiological properties. 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;.…”

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.

“…The observation that early peripheral visual representations are connected with caudal auditory cortex is consistent with a ''dorsal-pathway'' type function of these multisensory connections (Falchier et al 2002). Indeed, caudal auditory areas are considered to be part of a dorsal auditory stream, based on their connections with spatial domains of the frontal lobe and their role in sound spatial localization (Rauschecker 1998;Romanski, Bates, et al 1999;Romanski, Tian, et al 1999;Romanski and Goldman-Rakic 2002;Rauschecker and Tian 2004). Recent findings from fMRI connectivity analysis in humans showed that auditory cortex has a distinct relationship with the peripheral representation of visual field in the calcarine sulcus (Eckert et al 2008;Cate et al 2009).…”

Projection from Visual Areas V2 and Prostriata to Caudal Auditory Cortex in the Monkey

Studies in humans and monkeys report widespread multisensory interactions at or near primary visual and auditory areas of neocortex. The range and scale of these effects has prompted increased interest in interconnectivity between the putatively ''unisensory'' cortices at lower hierarchical levels. Recent anatomical tract-tracing studies have revealed direct projections from auditory cortex to primary visual area (V1) and secondary visual area (V2) that could serve as a substrate for auditory influences over low-level visual processing. To better understand the significance of these connections, we looked for reciprocal projections from visual cortex to caudal auditory cortical areas in macaque monkeys. We found direct projections from area prostriata and the peripheral visual representations of area V2. Projections were more abundant after injections of temporoparietal area and caudal parabelt than after injections of caudal medial belt and the contiguous areas near the fundus of the lateral sulcus. Only one injection was confined to primary auditory cortex (area A1) and did not demonstrate visual connections. The projections from visual areas originated mainly from infragranular layers, suggestive of a ''feedback''-type projection. The selective localization of these connections to peripheral visual areas and caudal auditory cortex suggests that they are involved in spatial localization.

a b s t r a c tA current view proposes that the right inferior frontal cortex (IFC) is particularly responsible for attentive decoding and cognitive evaluation of emotional cues in human vocalizations. Although some studies seem to support this view, an exhaustive review of all recent imaging studies points to an important functional role of both the right and the left IFC in processing vocal emotions. Second, besides a supposed predominant role of the IFC for an attentive processing and evaluation of emotional voices in IFC, these recent studies also point to a possible role of the IFC in preattentive and implicit processing of vocal emotions. The studies specifically provide evidence that both the right and the left IFC show a similar anterior-to-posterior gradient of functional activity in response to emotional vocalizations. This bilateral IFC gradient depends both on the nature or medium of emotional vocalizations (emotional prosody versus nonverbal expressions) and on the level of attentive processing (explicit versus implicit processing), closely resembling the distribution of terminal regions of distinct auditory pathways, which provide either global or dynamic acoustic information. Here we suggest a functional distribution in which several IFC subregions process different acoustic information conveyed by emotional vocalizations. Although the rostro-ventral IFC might categorize emotional vocalizations, the caudo-dorsal IFC might be specifically sensitive to their temporal features.
