The posterior part of the superior temporal gyrus (STG) has long been known to be a crucial hub for auditory and language processing, at the crossroad of the functionally defined ventral and dorsal pathways. Anatomical studies have shown that this “auditory cortex” is composed of several cytoarchitectonic areas whose…

Auditory cortex connectivity extends beyond the processing of acoustic stimuli, playing a crucial role in cognitive and emotional regulation through its interactions with higher-order brain regions. Although the neural mechanisms underlying acoustic information processing along the auditory pathway are well-documented…

Contrary to traditional thinking about hearing in which the broadband audio spectrum is taken as a whole, modern hearing science has gradually uncovered how the channel-based temporal envelope and its own spectrum are often prioritized by the auditory system. This is achieved through various processing mechanisms at…

The absence of auditory input, particularly during development, causes widespread changes in the structure and function of the auditory system, extending from peripheral structures into auditory cortex. In humans, the consequences of these changes are far-reaching and often include detriments to language acquisition…

No self-respecting concertgoer of a certain era would consider wearing earplugs at a show, but that was long before Pete Townsend and other rock icons spoke out about the risk of deafness. Today, most people recognize that high-intensity noise causes hearing loss-except maybe for those iPod users who routinely blast…

Human listeners need to permanently interact with their threedimensional (3-D) environment. To this end, they require efficient perceptual mechanisms to form a sufficiently accurate 3-D auditory space. In this chapter, we discuss the formation of the 3-D auditory space from various perspectives. The aim is to show the…

The mouse auditory cortex (ACtx) contains two core fields – A1 and AAF – arranged in a mirror reversal tonotopic gradient. The best frequency (BF) organization and naming scheme for additional higher-order fields remain a matter of debate, as does the correspondence between smoothly varying global tonotopy and…

The functional auditory system extends from the ears to the frontal lobes with successively more complex functions occurring as one ascends the hierarchy of the nervous system. Several areas of the frontal lobe receive afferents from both early and late auditory processing regions within the temporal lobe. Afferents…

Previous studies have demonstrated that auditory cortex activity can be influenced by cross-sensory visual inputs. Intracortical recordings in non-human primates (NHP) have suggested a bottom-up feedforward (FF) type laminar profile for auditory evoked but top-down feedback (FB) type for cross-sensory visual evoked…

No other modality is more frequently represented in the prefrontal cortex than the auditory, but the role of auditory information in prefrontal functions is not well understood. Pathways from auditory association cortices reach distinct sites in the lateral, orbital, and medial surfaces of the prefrontal cortex in…

'Helen J. Neville'] Brain reorganization associated with altered sensory experience clarifies the critical role of neuroplasticity in development. An example is enhanced peripheral visual processing associated with congenital deafness, but the neural systems supporting this have not been fully characterized. A gap in…

The auditory cortex (AC) sends long-range projections to virtually all subcortical structures important for hearing. One of the largest and most complex of these - the projection between AC and inferior colliculus (IC, the corticocollicular pathway) - has attracted attention due to its potential to alter IC response…

'Xingzhou Liu'] It has been well documented that the auditory system in the superior temporal cortex is responsible for processing basic auditory sound features, such as sound frequency and intensity, while the prefrontal cortex is involved in higher-order auditory functions, such as language processing and auditory…

The insular cortex is believed to be involved in a wide range of auditory functions in the mammalian brain. We studied the organization and basic response properties of auditory neurons in insular cortex and adjacent areas by recording responses to sound stimuli in anesthetized rats. Auditory neurons were present in an…

The functions of the medial geniculate body (MGB) in normal hearing still remain somewhat enigmatic, in part due to the relatively unexplored properties of the non-lemniscal MGB nuclei. Indeed, the canonical view of the thalamus as a simple relay for transmitting ascending information to the cortex belies a role in…

'Javad Safaie' 'Fabrice Wallois' 'Sahar Moghimi'] Abstract- Rhythm is a fundamental component of the auditory world, present even during the prenatal life. While there is evidence that some auditory capacities are already present before birth, whether and how the premature neural networks process auditory rhythm is yet…

Whether animal or speech communication, environmental sounds, or music – all sounds carry some information. Sound sources are embedded in acoustic environments that contain any number of additional sources that emit sounds that reach the listener's ears concurrently. It is up to the listener to decode the acoustic…
