“…One interesting characteristic of a visual optic flow stimulus is that it can produce a significant self-motion or a vection effect when separated from the inertial stimulus (62)(63)(64)(65)(66)(67), and this visually induced effect was then perceived as inertial motion itself. There is evidence of shared neurophysiology for visual and vestibular processing that is used to determine our motion through a fixed environment (68)(69)(70). The reason for this is that the vestibular organs sense only acceleration, so if motion continues at a constant linear velocity, there is no acceleration and thus no vestibular stimulus.…”

“…Second, the subject was asked only to report the inertial stimulus direction. Thus, they may not have truly been integrating the visual-inertial stimuli, and the neurophysiology seems to be different when subjects are asked to attend to only one modality (70). However, the strong bias of inertial heading perception toward the visual direction at most but not all timing delays tested suggests the timing delay was not ignored.…”

Heading direction is perceived based on visual and inertial cues. The current study examined the effect of their relative timing on the ability of offset visual headings to influence inertial perception. Seven healthy human subjects experienced 2 s of translation along a heading of 0°, ±35°, ±70°, ±105°, or ±140°. These inertial headings were paired with 2 s duration visual headings that were presented at relative offsets of 0°, ±30°, ±60°, ±90°, or ±120. The visual stimuli were also presented at 17 temporal delays ranging from -500 ms (visual lead) to 2,000 ms (visual delay) relative to the inertial stimulus. After each stimulus, subjects reported the direction of the inertial stimulus using a dial. The bias of the inertial heading towards the visual heading was robust at ±250 ms when examined across subjects during this period: 8.0 ± 0.5° with a 30° offset, 12.2 ± 0.5° with a 60° offset, 11.7 ± 0.6° with a 90° offset, and 9.8 ± 0.7° with a 120° offset (mean bias towards visual ± SE). The mean bias was much diminished with temporal misalignments of ±500 ms, and there was no longer any visual influence on the inertial heading when the visual stimulus was delayed by 1,000 ms or more. Although the amount of bias varied between subjects the effect of delay was similar.

“…However, these results did not show this trend. These results are discussed in terms of the process of real cursor identification from the perspective of visual search research.Past visual search tasks have shown that when searching for multiple objects, the dominance of serial and parallel processes varies from situation to situation [27][28][29] and that it is difficult to group multiple objects 30 . Furthermore, it has been reported that attention resources are limited only in the case of spatial configuration search 31,32 .…”

Virtual reality and robotics technologies have developed interactions with augmented and replicated bodies in digital space. By simultaneously moving multiple bodies in various locations in ample space, users can reach distant objects and interact with them by switching the bodies without having to make significant movements themselves. Previous researches has investigated the design interfaces for manipulation and switching in such interactions using multiple bodies based upon the user's perception of the objects. However, the mechanism by which a self-attribution arises from multiple objects reflecting self-motion is still unclear. To investigate this mechanism, we developed a dummy cursor experiment in which participants were presented with multiple independently moving dummy cursors in addition to the cursors they moved on the screen. The presented dummy cursors moved in different directions and were temporally synchronized with the participants' movements. Participants identified the cursor whose movement exactly matched the mouse they were manipulating from among the multiple dummy cursors displayed on the screen. To investigate under what conditions participants could identify the cursor they were operating, we compared the identification rates by varying the number of dummy cursors presented and how they were moved. As a result, participants could identify the cursor they were operating with a very high probability, even when there were many dummy cursors. Through these results, we discuss the occurrence of a self-attribution among multiple objects related to self-motion and the possibility of parameters contributing to self-attribution.

“…Regarding the time-frequency domain, Pfurtscheller et al (1994) and Klimesch et al (1990), Klimesch (1999) firstly, followed by others (Gomarus et al 2006, Rektor et al 2006, Wiesman et al 2017, Proskovec et al 2018, Townsend et al 2019 investigated different oscillatory modulation in different frequency bands during various visual cognitive tasks using event related desynchronizations/ synchronizations (ERD/ERS) analysis. They reported task-demand modulated ERD in alpha band during visual information processing, memorization tasks and attention allocation as well as beta band ERD, coupling with the alpha band ones, during processing of a visual cue and the preparation and execution of a motor action.…”

Objective: A large part of the cerebral cortex is dedicated to the processing of visual stimuli and there is still much to understand about such processing modalities and hierarchies. The main aim of the present study is to investigate the differences between Directional (DS) and non-Directional (n-DS) visual stimuli processing by time-frequency analysis of brain EEG activity during a visuo-motor task. EEG data were divided into 4 Regions of Interest (ROIs) (Frontal, Central, Parietal, Occipital). Approach: The analysis of the visual stimuli processing was based on the combination of electroencephalographic recordings and Time-frequency analysis. Event Related Spectral Perturbations (ERSPs) were computed with spectrum analysis that allow to obtain the average time course of relative changes induced by the stimulus presentation in spontaneous EEG amplitude spectrum. Main results: Visual stimuli processing enhanced the same pattern of spectral modulation in all investigated ROIs with differences in amplitudes and timing. Additionally, statistically significant differences in Occipital ROI between the DS and n-DS visual stimuli processing in theta, alpha and beta bands were found. Significance: These evidences suggest that ERSPs could be a useful tool to investigate the encoding of visual information in different brain regions. Because of their simplicity and their capability in the representation of brain activity, the ERSPs might be used as biomarkers of functional recovery for example in the rehabilitation of visual dysfunction and motor impairment following a stroke, as well as diagnostic tool of anomalies in brain functions in neurological diseases tailored to personalized treatments in clinical environment.
