“…The effect of adaptation to a specific motion direction has been commonly observed in hMT+/V5 (He et al, 1998;Hogendoorn and Verstraten, 2013;Huk et al, 2001;Tootell et al, 1995;Van Wezel 2002). Similarly, behavioral studies have provided compelling evidence for motion selective (Deas et al, 2008;Guerreiro et al, 2016;Kitagawa and Ichihara, 2002;Reinhardt-Rutland and Anstis, 1982) and direction-sensitive auditory motion aftereffects (aMAEs) (Dong et al, 2000;Grantham, 1998;Grantham and Wightman, 1979;Neelon and Jenison, 2003).…”

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.

“…Early studies typically failed to demonstrate an effect that was both convincing and reliable between observers (e.g. Grantham and Wightman 1979;Grantham 1989;Reinhardt-Rutland 1992). In contrast, the results of recent studies provide more compelling evidence that a robust and replicable aMAE does indeed exist (Grantham 1998;Dong et al 2000;Jenison 2003, 2004).…”

“…Critically, studies showing a strong aMAE have used stimuli containing all possible sources of motion information, produced either by physically moving a sound source through space (Dong et al 2000), by filtering sounds through generic head-related transfer functions (HRTFs) (Grantham 1998), or by filtering sounds with individually measured HRTFs Jenison 2003, 2004). In contrast, studies failing to find a substantial aMAE have typically opted to simulate auditory motion via dynamic manipulation of interaural timing and loudness cues (Grantham and Wightman 1979;Ehrenstein 1994;Reinhardt-Rutland 1992). Although these stimuli can produce a sensation of lateral motion, it is possible that they provide suboptimal stimulation to the auditory system.…”

Distortions of perceived auditory and visual space following adaptation to motion

Adaptation to visual motion can induce marked distortions of the perceived spatial location of subsequently viewed stationary objects. These positional shifts are direction specific and exhibit tuning for the speed of the adapting stimulus. In this study, we sought to establish whether comparable motion-induced distortions of space can be induced in the auditory domain. Using individually measured head related transfer functions (HRTFs) we created auditory stimuli that moved either leftward or rightward in the horizontal plane. Participants adapted to unidirectional auditory motion presented at a range of speeds and then judged the spatial location of a brief stationary test stimulus. All participants displayed direction-dependent and speed-tuned shifts in perceived auditory position relative to a 'no adaptation' baseline measure. To permit direct comparison between effects in different sensory domains, measurements of visual motion-induced distortions of perceived position were also made using stimuli equated in positional sensitivity for each participant. Both the overall magnitude of the observed positional shifts, and the nature of their tuning with respect to adaptor speed were similar in each case. A third experiment was carried out where participants adapted to visual motion prior to making auditory position judgements. Similar to the previous experiments, shifts in the direction opposite to that of the adapting motion were observed. These results add to a growing body of evidence suggesting that the neural mechanisms that encode visual and auditory motion are more similar than previously thought.

“…Properties include azimuthal motion of real moving sound sources (Dong, Swindale, Zakarauskas, Hayward, & Cynader, 2000;Grantham, 1989), simulated azimuthal motion employing dichotic differences of changing sound level and phase (Ehrenstein, 1984(Ehrenstein, , 1994Grantham & Wightman, 1979), and spectral filtering associated with the pinna (Kayahara, 2001;Shu, Swindale, & Cynader, 1993). In changing-loudness aftereffects-the principal concern of the present paper-listening to decreasing…”

Perceptual asymmetries associated with changing-loudness aftereffects

Listening to decreasing sound level leads to an increasing-loudness aftereffect, whereas listening to increasing sound level leads to a decreasing-loudness aftereffect. Measuring the aftereffects by nulling them in short test stimuli reveals that increasing-loudness aftereffects are greater than decreasingloudness aftereffects. However, this perceptual asymmetry may be due to another illusion-the growing-louder effect: In the absence of any adaptation, short steady stimuli are heard as growing louder. In an experiment in which the duration of test stimuli varied from 1.0 to 2.5 sec, the growinglouder effect did not occur in the longer test stimuli, but the asymmetry in changing-loudness aftereffects remained. The aftereffect asymmetry is therefore independent of the growing-louder effect. The aftereffect asymmetry is consistent with other psychophysical and physiological evidence that is believed to concern potential collision: An approaching sound-source elicits increasing sound level. In addition, the aftereffect asymmetry parallels a well-known asymmetry regarding aftereffects of visual motion, which is also attributed to potential collision.
