“…Overall, 80 % of participants reported the expected illusion within an interval of 15 seconds of synchronous stroking (Ehrsson, Holmes, & Passingham, 2005). Asynchronous stroking diminishes the effect or even eliminates the proprioceptive illusion as a consequence of the time delay between feeling and seeing the touch (Shimada, Suzuki, Yoda, & Hayashi, 2014). While visuotactile synchronicity in stimulation is a preponderant factor in the illusion, it cannot by itself explain the proprioceptive recalibration.…”

This review seeks to describe a multisensory integration hypothesis for proprioception through the description of different Rubber Hand Illusion (rhi) experimental settings. rhi is a paradigm created in 1998 to explore the relation between visual and tactile sensory systems. The task involves a synchronous stroking, using a paintbrush, of one of a subject's hands occluded from his vision, and a prosthetic rubber hand located in front of the subject. Instructed to look at the rubber hand, the subject starts to feel as if the rubber hand is his own hand after approximately half a minute, which is to say that the illusion produces a feeling of ownership of the rubber hand. Additional research over the last 15 years has widely explored these results, illustrating the dynamic functions of the brain and body sensory systems, as well as shedding light on the bases of amputee rehabilitation and different types of paresthesia. The review is structured around three topics: (1) the definition, limits, and scope of rhi; (2) the physiological and neurocognitive evidence backing rhi; and (3) the use of action based rhi experimental settings. The paper concludes that rhi is a salient example of a neuroscientific trend towards an integrated account of body, brain, and perceptual space. The discovery of the illusion has also provided an alternative context for the study of proprioception and related brain dynamics in normal subjects.

“…In apraxia, it is suggested that the sense of agency caused by the temporal integration of visual feedback and motor signals is lost (53), but no study has examined this issue. The time window for visuo-motor integration, i.e., the visuo-motor temporal integration function, which detects a temporal error between motor signals and visual feedback, can be evaluated quantitatively and objectively using a delayed visual feedback detection task (54–59). As apraxia involves an impairment of visuo-motor integration, the time window may also be distorted.…”

Distortion of Visuo-Motor Temporal Integration in Apraxia: Evidence From Delayed Visual Feedback Detection Tasks and Voxel-Based Lesion-Symptom Mapping

Limb apraxia is a higher brain dysfunction that typically occurs after left hemispheric stroke and its cause cannot be explained by sensory disturbance or motor paralysis. The comparison of motor signals and visual feedback to generate errors, i.e., visuo-motor integration, is important in motor control and motor learning, which may be impaired in apraxia. However, in apraxia after stroke, it is unknown whether there is a specific deficit in visuo-motor temporal integration compared to visuo-tactile and visuo-proprioceptive temporal integration. We examined the precision of visuo-motor temporal integration and sensory-sensory (visuo-tactile and visuo-proprioception) temporal integration in apraxia after stroke by using a delayed visual feedback detection task with three different conditions (tactile, passive movement, and active movement). The delay detection threshold and the probability curve for delay detection obtained in this task were quantitative indicators of the respective temporal integration functions. In addition, we performed subtraction and voxel-based lesion-symptom mapping to identify the brain lesions responsible for apraxia and deficits in visuo-motor temporal integration. The behavioral experiments showed that the delay detection threshold was extended and that the probability curve for delay detection was less steep in apraxic patients compared to controls (pseudo-apraxic patients and unaffected patients), only for the active movement condition, and not for the tactile and passive movement conditions. Furthermore, the severity of apraxia was significantly correlated with the delay detection threshold and the steepness of the probability curve in the active movement condition. These results indicated that multisensory (i.e., visual, tactile, and proprioception) feedback was normally temporally integrated, but motor prediction and visual feedback were not correctly temporally integrated in apraxic patients. That is, apraxic patients had difficulties with visuo-motor temporal integration. Lesion analyses revealed that both apraxia and the distortion of visuo-motor temporal integration were associated with lesions in the fronto-parietal motor network, including the left inferior parietal lobule and left inferior frontal gyrus. We suppose that damage to the left inferior fronto-parietal network could cause deficits in motor prediction for visuo-motor temporal integration, but not for sensory-sensory (visuo-tactile and visuo-proprioception) temporal integration, leading to the distortion of visuo-motor temporal integration in patients with apraxia.

“…To estimate each observer's delay detection threshold (DDT), representing the delay length at which the delay detection probability is 50%, logistic curves were fitted to each participant's responses based on the following formula (Afraz et al, 2006;Shimada et al, 2010Shimada et al, , 2014:…”

The sense of agency (SoA) refers to the subjective feeling that an individual can control their own action with their own will. However, it is still unclear which aspects of the motor control process precisely affect the sense of agency. In this study, we investigated how the SoA is modulated by the online motor performance (trajectory error) and the outcome of the reaching movement (endpoint error). The results showed that the invalid priming and the visual feedback delay significantly increased both the trajectory and endpoint errors and that these errors significantly attenuated the SoA. The further correlation analyses showed that the decrease in SoA was significantly correlated with the trajectory error, but not with the endpoint error, when the error was explicitly noticed. We suggest that the deterioration in online motor performance, at least in a reaching movement, is the main cause of the attenuation in the SoA.
