“…These findings not only extend previous recordings in the insula which relied on simplistic stimuli (Pribram et al, 1954;Sudakov et al, 1971;Bieser and Müller-Preuss, 1996;Bieser, 1998) but are also in good agreement with results from human imaging and lesion studies, which implicate the insula in the processing of complex sounds and speech (Augustine, 1985;Bamiou et al, 2003). Given the structural similarity of the insula and auditory pathways across humans and monkeys, our findings have direct implications on the mechanisms operating in the human brain (Hackett et al, 2001;Chiry et al, 2003;Sweet et al, 2005;Ghazanfar, 2008).…”

Human imaging studies implicate the insular cortex in processing complex sounds and vocal communication signals such as speech. In addition, lesions of the insula often manifest as deficits in sound or speech recognition (auditory agnosia) and speech production. While models of acoustic perception assign an important role to the insula, little is known about the underlying neuronal substrate. Studying a vocal primate, we identified a predominantly auditory region in the caudal insula and therein discovered a neural representation of conspecific communication sounds. When probed with natural sounds, insula neurons exhibited higher response selectivity than neurons in auditory cortex, and in contrast to these, responded preferentially to conspecific vocalizations. Importantly, insula neurons not only preferred conspecific vocalizations over a wide range of environmental sounds and other animal vocalizations, but also over acoustically manipulated versions of these, demonstrating that this preference for vocalizations arises both from spectral and temporal features of the sounds. In addition, individual insula neurons responded highly selectively to only a few vocalizations and allowed the decoding of sound identity from single-trial responses. These findings characterize the caudal insula as a selectively responding auditory region, possibly part of a processing stream involved in the representation of communication sounds. Importantly, our results provide a neural counterpart for the human imaging and lesion findings and uncover a basis for a supposed role of the insula in processing vocal communication sounds such as speech.

“…They found that large expanses of the neocortex were activated by sounds, including unimodal visual areas in the temporal and parietal lobes. This extensive activation of visual areas by auditory stimuli is reminiscent of an earlier finding by Pribram et al [59]: using auditory clicks as stimuli and field potential recordings in anesthetized monkeys, they found that, beyond traditional auditory areas, much of the superior temporal gyrus, insula and parts of the parietal lobe were responsive. Single unit recordings in monkeys performing a crossmodal delayed-match-to-sample task also revealed sample- [60] and delay-period [60] auditory activity in IT cortex.…”

Although sensory perception and neurobiology are traditionally investigated one modality at a time, real world behaviour and perception are driven by the integration of information from multiple sensory sources. Mounting evidence suggests that the neural underpinnings of multisensory integration extend into early sensory processing. This article examines the notion that neocortical operations are essentially multisensory. We first review what is known about multisensory processing in higher-order association cortices and then discuss recent anatomical and physiological findings in presumptive unimodal sensory areas. The pervasiveness of multisensory influences on all levels of cortical processing compels us to reconsider thinking about neural processing in unisensory terms. Indeed, the multisensory nature of most, possibly all, of the neocortex forces us to abandon the notion that the senses ever operate independently during real-world cognition.

“…The suggestion that the main associative outflow of the auditory cortex is in the anterior part of the supratemporal plane receives some support in the work of Pribram et al (1954). They found in the macaque that the region of short-latency responses to click lay posterior in the supratemporal plane; there was an anterior strip in which responses of much longer latency were seen.…”

“…Further research on the auditory system of primates should help to clarify these questions further. Important steps in overcoming the technical difficulties in this field were made by Pribram et al (1954); further advances in knowledge may be expected to result from such improvements in technique.…”
