“…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).…”

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.

“…Although there is considerable evidence of direct anatomical connections between auditory cortical regions in the temporal lobe and the ventrolateral prefrontal cortex (14)(15)(16)(17)(18)(19)(20) and the presence of auditory responsive neurons for complex sounds in the ventrolateral prefrontal cortex (21,22), there is no study examining the potential involvement of the ventrolateral prefrontal region in the controlled selective retrieval of auditory nonverbal information in the human brain. Most studies investigating the role of the prefrontal cortex in the auditory domain have focused on verbal phonological and semantic memory (23)(24)(25).…”

“…Given the evidence for specialized areas involved in auditory processing in the superior temporal region (47) and the anatomical connections of the midventrolateral prefrontal region to the auditory temporal region and adjacent inferior parietal lobule (14)(15)(16)(17)(18)(19)(20), it can be hypothesized that the midventrolateral prefrontal cortex plays a key role in the isolation of particular aspects of memorized auditory stimuli in interaction with specific posterior temporoparietal cortical areas by enhancing relevant and inhibiting irrelevant features. This interaction was reflected in the increased connectivity of the midventrolateral prefrontal cortex with these specific posterior association cortical regions.…”

There is evidence from the visual, verbal, and tactile memory domains that the midventrolateral prefrontal cortex plays a critical role in the top-down modulation of activity within posterior cortical areas for the selective retrieval of specific aspects of a memorized experience, a functional process often referred to as active controlled retrieval. In the present functional neuroimaging study, we explore the neural bases of active retrieval for auditory nonverbal information, about which almost nothing is known. Human participants were scanned with functional magnetic resonance imaging (fMRI) in a task in which they were presented with short melodies from different locations in a simulated virtual acoustic environment within the scanner and were then instructed to retrieve selectively either the particular melody presented or its location. There were significant activity increases specifically within the midventrolateral prefrontal region during the selective retrieval of nonverbal auditory information. During the selective retrieval of information from auditory memory, the right midventrolateral prefrontal region increased its interaction with the auditory temporal region and the inferior parietal lobule in the right hemisphere. These findings provide evidence that the midventrolateral prefrontal cortical region interacts with specific posterior cortical areas in the human cerebral cortex for the selective retrieval of object and location features of an auditory memory experience.fMRI | prefrontal cortex | memory retrieval | auditory | control processes

“…Along the same line, the prefrontal cortex, playing a role in temporal integration, receives projections from the auditory and the visual cortices (e.g. Gaffan and Harrison, 1991;Romanski et al, 1999;Fuster et al, 2000). Still in the monkey, a network of inter-connected multisensory areas playing a role in the perception of visual, auditory and tactile stimuli presented in a part of space close to the body was described, involving the putamen, the premotor cortex, VIP and the parietal area 7b (Graziano and Gross, 1998;Graziano, 2001).…”

In order to interact with the multisensory world that surrounds us, we must integrate various sources of sensory information (vision, hearing, touch. . .). A fundamental question is thus how the brain integrates the separate elements of an object defined by several sensory components to form a unified percept. The superior colliculus was the main model for studying multisensory integration. At the cortical level, until recently, multisensory integration appeared to be a characteristic attributed to high-level association regions. First, we describe recently observed direct cortico-cortical connections between different sensory cortical areas in the non-human primate and discuss the potential role of these connections. Then, we show that the projections between different sensory and motor cortical areas and the thalamus enabled us to highlight the existence of thalamic nuclei that, by their connections, may represent an alternative pathway for information transfer between different sensory and/or motor cortical areas. The thalamus is in position to allow a faster transfer and even an integration of information across modalities. Finally, we discuss the role of these non-specific connections regarding behavioral evidence in the monkey and recent electrophysiological evidence in the primary cortical sensory areas.
