“…In line with several studies investigating auditory motion processing, our univariate results demonstrated a preference for moving over static sounds in the superior temporal gyri, bilateral hPT, precentral gyri, and anterior portion of middle temporal gyrus in both hemispheres (Baumgart and Gaschler-Markefski, 1999;Krumbholz et al, 2005;Pavani et al, 2002;Poirier et al, 2005;Warren et al, 2002).…”

“…This proposition is supported by early animal electrophysiological studies suggesting the existence of neurons in the auditory cortex that are selective to sound source location and motion directions (Altman, 1968(Altman, , 1994Benson et al, 1981;Doan et al, 1999;Imig et al, 1990;Middlebrooks and Pettigrew, 1981;Poirier et al, 1997;Rajan et al, 1990), which display similar response profiles for moving and sound source locations (Ahissar et al, 1992;Doan et al, 1999;Poirier et al, 1997). In contrast, other studies in animals (Poirier et al, 2017) and humans (Baumgart and Gaschler-Markefski, 1999;Bremmer et al, 2001;Griffiths et al, 1998;Hall and Moore, 2003;Krumbholz et al, 2005;Lewis et al, 2000;Pavani et al, 2002;Poirier et al, 2005) pointed toward a more specific role of hPT for auditory motion processing. In addition to the shared or distinct nature of the neural representation of auditory motion and location in the hPT, the characteristic tuning of this region for separate direction or axis of motion/location remains unknown.…”

“…One candidate region that might integrate spatial cues to compute motion and location information in the human auditory cortex is the planum temporale (hPT) (Barrett and Hall, 2006;Baumgart and Gaschler-Markefski, 1999;. hPT is located in the superior temporal gyrus, posterior to Helsch' gyrus, and is typically considered part of the dorsal auditory stream (Poirier et al, 2017;Rauschecker and Tian, 2000;Recanzone, 2000;Romanski et al, 1999;Tian et al, 2001).…”

The ability to precisely compute the location and direction of sounds in external space is a crucial perceptual process to efficiently interact with dynamic environments. Little is known, however, about how the human brain implements spatial hearing. In our study, we used fMRI to characterize the brain activity of humans listening to left, right, up and down moving as well as static sounds. Whole brain univariate results contrasting moving and static sounds varying in their location revealed a robust functional preference for auditory motion in bilateral human Planum Temporale (hPT). Importantly, multivariate pattern classification analysis showed that hPT contains information about both auditory motion directions and, to a lesser extent, sound source locations. More precisely, we observed that our classifier successfully decoded opposite axes of motion (vertical versus horizontal) but was less able to classify opposite within-axis direction (left versus right or up versus down); reminiscent of the axis of motion organization observed in the middle-temporal cortex for vision. Further multivariate analyses demonstrated that even if motion direction and location rely on partially shared pattern geometries in PT, the responses elicited by static and moving sounds were however highly distinct. Altogether our results demonstrate that human PT codes for auditory motion and location but that the underlying neural computation linked to motion processing is more reliable and partially distinct from the one supporting sound source location.All rights reserved.

“…The findings have implicated parietal lobe structures in spatial processing (Bushara et al, 1999;Alain et al, 2001;Maeder et al, 2001), which are likely related to sensorimotor integration and spatial transformations required for active localization tasks (Zatorre et al, 2002b). Auditory cortical areas posterior to A1 are recruited by stimuli moving in space (Baumgart et al, 1999;Griffiths and Green, 1999;Warren et al, 2002) or by situations in which multiple stimuli must be disambiguated on the basis of spatial cues (Zatorre et al, 2002b). These findings and others have led to the suggestion that posterior cortical regions may perform a computation related to the segregation and matching of spectrotemporal patterns .…”

This positron emission tomography study examined the hemodynamic response of the human brain to auditory object feature processing. A continuum of object feature variation was created by combining different numbers of stimuli drawn from a diverse sample of 45 environmental sounds. In each 60 sec scan condition, subjects heard either a distinct individual sound on each trial or simultaneous combinations of sounds that varied systematically in their similarity or distinctiveness across conditions. As more stimuli are combined they become more similar and less distinct from one another; the limiting case is when all 45 are added together to form a noise that is repeated on each trial. Analysis of covariation of cerebral blood flow elicited by this parametric manipulation revealed a response in the upper bank of the right anterior superior temporal sulcus (STS): when sounds were identical across trials (i.e., a noise made up of 45 sounds), activity was at a minimum; when stimuli were different from one another, activity was maximal. A right inferior frontal area was also revealed. The results are interpreted as reflecting sensitivity of this region of temporal neocortex to auditory object features, as predicted by neurophysiological and anatomical models implicating an anteroventral functional stream in object processing. The findings also fit with evidence that voice processing may involve regions within the anterior STS. The data are discussed in light of these models and are related to the concept that this functional stream is sensitive to invariant sound features that characterize individual auditory objects.

“…An anterior pathway is thought to process the nonspatial attributes of auditory stimuli (Zatorre et al, 1992;Griffiths et al, 1998;Scott et al, 2000;Maeder et al, 2001;Vouloumanos et al, 2001;Patterson et al, 2002;Hart et al, 2004). A posterior pathway that includes regions of inferior parietal lobule is thought to process the spatial attributes of an auditory stimulus (Baumgart et al, 1999;Alain et al, 2001;Maeder et al, 2001;Warren et al, 2002;Hart et al, 2004). The areas of the auditory cortex and the frontal and parietal areas that constitute these two pathways are thought to be analogous to those areas identified as important for spatial and nonspatial processing in the rhesus monkey (Romanski et al, 1999;Rauschecker and Tian, 2000).…”

Spatial and nonspatial auditory processing is hypothesized to occur in parallel dorsal and ventral pathways, respectively. In this study, we tested the spatial and nonspatial sensitivity of auditory neurons in the ventrolateral prefrontal cortex (vPFC), a cortical area in the hypothetical nonspatial pathway. We found that vPFC neurons were modulated significantly by both the spatial and nonspatial attributes of an auditory stimulus. When comparing these responses with those in anterolateral belt region of the auditory cortex, which is hypothesized to be specialized for processing the nonspatial attributes of auditory stimuli, we found that the nonspatial sensitivity of vPFC neurons was poorer, whereas the spatial selectivity was better than anterolateral neurons. Also, the spatial and nonspatial sensitivity of vPFC neurons was comparable with that seen in the lateral intraparietal area, a cortical area that is a part of the dorsal pathway. These data suggest that substantial spatial and nonspatial processing occurs in both the dorsal and ventral pathways.
