“…paired stationary locations in the same direction ranges. Analogous results were also found in a subsequent ERP study (Getzmann et al, 2011), which compared suppression of responses to moving sounds (to left or right from 0 degrees) that followed either stationary (0 degrees, or 32 degrees to the right or left) or “scattered” adaptor sounds (scattered directions 0–32 degrees right or left, or from 32 left to 32 right). EEG responses were adapted most pronouncedly by a scattered adaptor that was spatially congruent with the motion probe.…”

Localization of sound sources is a considerable computational challenge for the human brain. Whereas the visual system can process basic spatial information in parallel, the auditory system lacks a straightforward correspondence between external spatial locations and sensory receptive fields. Consequently, the question how different acoustic features supporting spatial hearing are represented in the central nervous system is still open. Functional neuroimaging studies in humans have provided evidence for a posterior auditory “where” pathway that encompasses non-primary auditory cortex areas, including the planum temporale (PT) and posterior superior temporal gyrus (STG), which are strongly activated by horizontal sound direction changes, distance changes, and movement. However, these areas are also activated by a wide variety of other stimulus features, posing a challenge for the interpretation that the underlying areas are purely spatial. This review discusses behavioral and neuroimaging studies on sound localization, and some of the competing models of representation of auditory space in humans.

“…Electrophysiological studies in animals demonstrated that motionselective neurons in the auditory cortex displayed similar response profile to sounds located or moving toward the same position in external space, suggesting that the processing of sound-source locations may contribute to the perception of moving sounds (Ahissar et al, 1992;Doan et al, 1999;Poirier et al, 1997). Results from human psychophysiological and auditory evoked potential studies also strengthen the notion that sound source location contributes to motion perception (Getzmann and Lewald, 2011;Strybel and Neale, 1994). Our cross-condition MVPA results therefore extend the notion that motion directions and sound source locations might have common features that are shared for encoding spatial sounds.…”

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.

“…For example, an individual has to track the movement of prey and identify whether it is moving towards or away from the individual in a forest. Previous studies have shown that spatial adaptation plays a role in auditory motion processing [9]. Moreover, some studies have reported distinct neural generators for generating evoked response to sound pitch or location [73].…”

“…Studies using event-related potentials (ERPs) have consistently reported a reduction in the amplitude of a negative wave peaking at about 100 ms after sound onset (N1) with stimulus repetition [6,7,8]. Other studies have shown reduced P2 amplitudes (positive wave peaking at about 180 ms post-stimulus) for sounds coming from identical spatial locations [9]. These patterns of neural adaptation have been related to increased cognitive efficiency, such as improved stimulus identification [10], auditory memory [11], and rapid learning [7].…”

Much of what we know regarding the effect of stimulus repetition on neuroelectric adaptation comes from studies using artificially produced pure tones or harmonic complex sounds. Little is known about the neural processes associated with the representation of everyday sounds and how these may be affected by aging. In this study, we used real life, meaningful sounds presented at various azimuth positions and found that auditory evoked responses peaking at about 100 and 180 ms after sound onset decreased in amplitude with stimulus repetition. This neural adaptation was greater in young than in older adults and was more pronounced when the same sound was repeated at the same location. Moreover, the P2 waves showed differential patterns of domain-specific adaptation when location and identity was repeated among young adults. Background noise decreased ERP amplitudes and modulated the magnitude of repetition effects on both the N1 and P2 amplitude, and the effects were comparable in young and older adults. These findings reveal an age-related difference in the neural processes associated with adaptation to meaningful sounds, which may relate to older adults’ difficulty in ignoring task-irrelevant stimuli.
