“…Recent evidence indicates that the combined encoding of sound object identity and location involves a separate, third processing stream, referred to also as the lateral pathway (Clarke and Geiser, 2015). Its initial demonstration relied on repetition priming paradigms; neural populations, which encoded the combined representation, displayed repetition enhancement when an object changed position and repetition suppression when it did not, both in EEG (Bourquin et al, 2013) and in 7T fMRI experiments (Da Costa et al, 2018).…”

Evidence from behavioral studies suggests that the spatial origin of sounds may influence the perception of emotional valence. Using 7T fMRI we have investigated the impact of the categories of sound (vocalizations; non-vocalizations), emotional valence (positive, neutral, negative) and spatial origin (left, center, right) on the encoding in early-stage auditory areas and in the voice area. The combination of these different characteristics resulted in a total of 18 conditions (2 categories x 3 valences x 3 lateralizations), which were presented in a pseudo-randomized order in blocks of 11 different sounds (of the same condition) in 12 distinct runs of 6 min. In addition, two localizers, i.e., tonotopy mapping; human vocalizations, were used to define regions of interest. A three-way repeated measure ANOVA on the BOLD responses revealed bilateral significant effects and interactions in the primary auditory cortex, the lateral early-stage auditory areas, and the voice area. Positive vocalizations presented on the left side yielded greater activity in the ipsilateral and contralateral primary auditory cortex than did neutral or negative vocalizations or any other stimuli at any of the three positions. Right, but not left area L3 responded more strongly to (i) positive vocalizations presented ipsi- or contralaterally than to neutral or negative vocalizations presented at the same positions; and (ii) to neutral than positive or negative non-vocalizations presented contralaterally. Furthermore, comparison with a previous study indicates that spatial cues may render emotional valence more salient within the early-stage auditory areas.

“…Sounds are an important source of information for all mammals (Oertel, Cao, Ison, & Allen, 2017). They are mostly used for locating other animals, especially when visual information is limited (Clarke & Geiser, 2015). For people, sounds are not only a source of spatial information, but also of emotional experiences (Duffy, Waitt, & Harada, 2016).…”

“…Furthermore, humans categorize sounds in many different ways, for example separating verbal from non-verbal sounds (even infants can do this, Wild et al, 2017), separating action-related sounds from action-unrelated sounds, or distinguishing vocalization sounds produced by living organisms and man-made items, such as tools (Lewis, Brefczynski, Phinney, Janik, & DeYoe, 2005, see also Crivelli, Rueda, & Balconi, 2018;Schneider, Sundararajan, & Mooney, 2018). Interestingly, when processing action-related sounds, including tool sounds, one can observe neural activity in motorrelevant areas of the human brain (Lewis, Phinney, Brefczynski-Lewis, & DeYoe, 2006;Bourquin, Simonin, & Clarke, 2013;Clarke & Geiser, 2015), and in areas related to recognition and performance of actions (Rizzolatti et al, 1996;D'Ausilio et al, 2009), such as Broca's area (Binkofski & Buccino, 2004;Corballis, 2010). Similar effects have also been observed in nonhuman primates.…”

health psychology report • volume 8(1),  original article background The impact of bilingualism on lateralized brain functions such as praxis -the control of skilled actions -and language representations themselves, particularly in the auditory domain, is still largely unknown. Recent studies suggest that bilingualism affects both basic (fundamental frequency) sound and action-related speech processing. Whether it can impact non-verbal action sound processing is a question of debate. participants and procedureHere we examined twenty bilinguals using a dichotic listening paradigm, in which in addition to repeating the just heard action words, participants named -in Polish or English -one of two simultaneously presented tool sounds from attended ears. The results were compared with data from these same participants tested with reading the same words in a visual-half field paradigm. resultsIn contrast to typical outcomes from monolinguals, the laterality indices of action-related sound processing (verbal and non-verbal) were not left lateralized but hemispherically balanced. Notably, despite similar organization of tool-and action-word sound processing, their auditory (balanced) and visual-language (left-lateralized) representations might be independent because there were no significant correlations between any of their laterality indices. conclusionsThis indicates that bilingualism might involve reshuffling/ reorganization of typically lateralized brain functions and such plasticity will have consequences for second language learning strategies, as well as for neurorehabilitation.

“…Eramudugolla and colleagues have shown that the discrimination of animal cries and musical instruments among distractors benefits from spatial cues when the target sound is short (250 ms) but not long (500 ms) [45]. In contrast to the above quoted studies, which used meaningful sounds as targets, the contribution of spatial cues to the segregation of meaningless, previously unheard sound events is less clear [46,47].…”

Auditory spatial cues contribute to two distinct functions, of which one leads to explicit localization of sound sources and the other provides a location-linked representation of sound objects. Behavioral and imaging studies demonstrated right-hemispheric dominance for explicit sound localization. An early clinical case study documented the dissociation between the explicit sound localizations, which was heavily impaired, and fully preserved use of spatial cues for sound object segregation. The latter involves location-linked encoding of sound objects. We review here evidence pertaining to brain regions involved in location-linked representation of sound objects. Auditory evoked potential (AEP) and functional magnetic resonance imaging (fMRI) studies investigated this aspect by comparing encoding of individual sound objects, which changed their locations or remained stationary. Systematic search identified 1 AEP and 12 fMRI studies. Together with studies of anatomical correlates of impaired of spatial-cue-based sound object segregation after focal brain lesions, the present evidence indicates that the location-linked representation of sound objects involves strongly the left hemisphere and to a lesser degree the right hemisphere. Location-linked encoding of sound objects is present in several early-stage auditory areas and in the specialized temporal voice area. In these regions, emotional valence benefits from location-linked encoding as well.
