“…The sharpening of tuning curves may allow for finer frequency analysis at a wider range of frequencies, whereas the flattening of these curves may function to stabilize responsiveness to specific frequency bands. A similar experiment looking at visual modulation of auditory responses as a function of sound pressure level in IC revealed sound pressure levelspecific enhancement or suppression of activity (Cheng et al 2020). Visual modulation was strongest for stimuli presented at a given neuron's preferred auditory azimuth.…”

“…Visual modulation was strongest for stimuli presented at a given neuron's preferred auditory azimuth. Thus, while it is unlikely that visual modulation plays an essential role in the formation of an auditory space map in the mammalian IC, it might have the ability to modulate this map by increasing sound level sensitivity (Cheng et al 2020).…”

In a naturalistic environment, auditory cues are often accompanied by information from other senses, which can be redundant with or complementary to the auditory information. Although the multisensory interactions derived from this combination of information and that shape auditory function are seen across all sensory modalities, our greatest body of knowledge to date centers on how vision influences audition. In this review, we attempt to capture the state of our understanding at this point in time regarding this topic. Following a general introduction, the review is divided into 5 sections. In the first section, we review the psychophysical evidence in humans regarding vision’s influence in audition, making the distinction between vision’s ability to enhance versus alter auditory performance and perception. Three examples are then described that serve to highlight vision’s ability to modulate auditory processes: spatial ventriloquism, cross-modal dynamic capture, and the McGurk effect. The final part of this section discusses models that have been built based on available psychophysical data and that seek to provide greater mechanistic insights into how vision can impact audition. The second section reviews the extant neuroimaging and far-field imaging work on this topic, with a strong emphasis on the roles of feedforward and feedback processes, on imaging insights into the causal nature of audiovisual interactions, and on the limitations of current imaging-based approaches. These limitations point to a greater need for machine-learning-based decoding approaches toward understanding how auditory representations are shaped by vision. The third section reviews the wealth of neuroanatomical and neurophysiological data from animal models that highlights audiovisual interactions at the neuronal and circuit level in both subcortical and cortical structures. It also speaks to the functional significance of audiovisual interactions for two critically important facets of auditory perception—scene analysis and communication. The fourth section presents current evidence for alterations in audiovisual processes in three clinical conditions: autism, schizophrenia, and sensorineural hearing loss. These changes in audiovisual interactions are postulated to have cascading effects on higher-order domains of dysfunction in these conditions. The final section highlights ongoing work seeking to leverage our knowledge of audiovisual interactions to develop better remediation approaches to these sensory-based disorders, founded in concepts of perceptual plasticity in which vision has been shown to have the capacity to facilitate auditory learning.
