“…Previous research has investigated spatial updating across body translation in complete darkness using psychophysical procedure where participants have to compare the position of a probe target to a reference [17,19]. Despite the similarity with our test trials where a probe target was shown at the end of the translation, the aim of these studies was in fact closer to the goal of our updating-only trials: measuring how an observer updates an object position based on vestibular cues only.…”

Author Summary 35A change of an object's position on our retina can be caused by a change of the object's location 36 in the world or by a movement of the eye and body. Here, we examine how the brain solves 37 this problem for spatial updating by assessing the probability that the internally-updated 38 location during body motion and observed retinal feedback after the motion stems from the 39 same object location in the world. Guided by Bayesian causal inference model, we demonstrate 40 that participants' errrors in spatial updating depend nonlinearly on the spatial discrepancy 41 between internally-updated and reafferent visual feedback about the object's location in the 42 world. We propose that the brain implicitly represents the probability that the internally updated 43 estimate and the sensory feedback come from a common cause, and use this probability to 44 weigh the two sources of information in mediating spatial constancy across whole-body motion. 45

“…Model fits revealed that an object-based reference frame could also contribute to spatial updating. This speaks to the notion that the brain defines line information in multiple reference frames in parallel, perhaps depending on their reliability (McGuire & Sabes, 2009;Tramper & Medendorp, 2015). In this study, the visual frame had only a minor contribution to the updating performance.…”

“…If one of the references changes, the spatial relationship needs to be recomputed to maintain a correct registry with its true spatial orientation in the world. This is referred to as spatial updating, and has been studied extensively in relation to single points (Baker, Harper, & Snyder, 2013;Bloomberg, Jones, Segal, McFarlane, & Soul, 1988;Clemens, Selen, Koppen, & Medendorp, 2012;Gutteling, Selen, & Medendorp, 2015;Israël, Ventre-Dominey, & Denise, 1999;Klier & Angelaki, 2008;Tramper & Medendorp, 2015;Van Pelt, Van Gisbergen, & Medendorp, 2005).…”

“…Finally, it could be considered that the updating is not restricted to using a single reference frame, but that multiple reference frames are used in the maintenance of line orientation (cf. Tramper & Medendorp, 2015). Here, we investigated the role of allocentric and egocentric reference frames in the updating of line orientation across head rotations.…”

Updating of visual orientation in a gravity-based reference frame

The brain can use multiple reference frames to code line orientation, including head-, object-, and gravity-centered references. If these frames change orientation, their representations must be updated to keep register with actual line orientation. We tested this internal updating during head rotation in roll, exploiting the rod-and-frame effect: The illusory tilt of a vertical line surrounded by a tilted visual frame. If line orientation is stored relative to gravity, these distortions should also affect the updating process. Alternatively, if coding is head- or frame-centered, updating errors should be related to the changes in their orientation. Ten subjects were instructed to memorize the orientation of a briefly flashed line, surrounded by a tilted visual frame, then rotate their head, and subsequently judge the orientation of a second line relative to the memorized first while the frame was upright. Results showed that updating errors were mostly related to the amount of subjective distortion of gravity at both the initial and final head orientation, rather than to the amount of intervening head rotation. In some subjects, a smaller part of the updating error was also related to the change of visual frame orientation. We conclude that the brain relies primarily on a gravity-based reference to remember line orientation during head roll.

“…When the body moves, these body-centered representations are also no longer in register with external space, unless they are actively updated. Recently, we addressed the question of whether the state estimator updates the representations in the various reference frames simultaneously, or whether it relies on a single frame for updating, from which representations in other reference frame are subsequently constructed (Tramper and Medendorp, 2015).…”

The vestibular system, which detects motion and orientation of the head in space, is known to be important in controlling gaze to stabilize vision, to ensure postural stability and to provide our sense of self-motion. While the brain's computations underlying these functions are extensively studied, the role of the vestibular system in higher level sensorimotor functions is less clear. This review covers new research on the vestibular influence on perceptual judgments, motor decisions, and the ability to learn multiple motor actions. Guided by concepts such as optimization, inference, estimation and control, we focus on how the brain determines causal relationships between memorized and visual representations in the updating of visual space, and how vestibular, visual and efferent motor information are integrated in the estimation of body motion. We also discuss evidence that these computations involve multiple coordinate representations, some of which can be probed in parietal cortex using neuronal oscillations derived from EEG. In addition, we describe work on decision making during self-motion, showing a clear modulation of bottom-up acceleration signals on decisions in the saccadic system. Finally, we consider the importance of vestibular signals as contextual cues in motor learning and recall. Taken together, these results emphasize the impact of vestibular information on high-level sensorimotor functions, and identify future directions for theoretical, behavioral, and neurophysiological investigations.
