Summary: The study investigates the functional anatomy of OP2 and adjacent areas in the posterior peri-sylvian cortex, which is proposed to be the core human vestibular cortex. The results show that different functional subregions of OP2 exhibit strong connectivity to other vestibular areas and distinct responses to visual and caloric stimulation, suggesting a central role for vestibular function in health and disease.

Summary: The study investigates the value of vestibular graviceptive pathway (VGP) evaluation in the diagnosis of unilateral peripheral vestibular dysfunction (UPVD) patients. Results show that alterations in subjective visual vertical (SVV), subjective visual horizontal (SVH), ocular torsion (OT), and skew deviation (SD) are related to dynamic vestibular compensation in UPVD patients. Correlations between VGP evaluation results and cochleovestibular function test results suggest that VGP evaluation is helpful for the diagnosis of the affected side in UPVD. The presence of contralesional VGP (c-VGP) may be associated with bilateral labyrinth lesions or endolymphatic hydrops on the affected side, and autoimmune mechanisms should also be considered.

Summary: The recovery time course of otolithic dis-function caused by superior vestibular neuritis varies among patients, with most patients seeing a return to normal values within a few months for subjective visual vertical but remaining abnormal for ocular cyclotorsion even a year later. The dissociation between the recovery of these two signs suggests distinct re-balancing circuits within the otolithic system.

Summary: The evaluation of the ocular tilt reaction (OTR) plus head tilt subjective visual vertical (SVV) is helpful for identifying and diagnosing patients with acute central vascular vertigo (ACVV), especially when the skew deviation (SD) is equal or greater than 3 degrees or when the E-effect is symmetrically increased.

Summary: This study investigates the contribution of visual and haptic cues to depth discontinuity in processing occlusion. The results show that while both cues affect the confidence in depth estimation, only the visual cue has a positive impact on word recognition performance, while the haptic cue does not. This suggests that the human brain predominantly relies on visual input when processing occlusion.

Summary: This study investigates the role of low-frequency oscillations in 3D perception with depth cues, using visual stimuli presented by virtual reality technology. The findings suggest that low-frequency delta and theta bands are specific to stereoscopic vision and show increased functional connectivity in cortical areas related to visual pathways.

Summary: This study explores the possibility of increasing the speed and accuracy of users' discrimination of realistic targets presented within a short timeframe. The findings show that spoken cues, particularly in bimodal form, can effectively boost performance under time pressure and limited information in real-world scenarios. However, the timing of the cues and congruency between response and target location can also impact task performance.

Summary: The perception of vertical relies on vestibular and visual cues. This study found that sustained exposure to panoramic and vestibular cues has a local effect on the subsequent perception of vertical, which is mediated by head orientation.

Summary: The study focused on visual spatial information processing in chronic AUD patients during abstinence by examining the tilt illusion effect. Results showed significantly weaker tilt repulsion effect at +/- 15 degrees surround orientation and higher lapse rate in patients with chronic AUD compared to healthy controls under all tested surround orientations. These findings provide psychophysical evidence of differences in visual perception between AUD patients and healthy controls.

Summary: The mammalian vestibular efferent system remains a mystery, as it does not relay inputs from other sensory modalities or motor-related signals to the vestibular periphery, but likely plays a key role in calibrating and protecting vestibular circuits during development and aging.

Summary: This study investigated the effect of bone-conducted vibration (BCV) on the sensation of vection through two experiments. The results suggested that 500 Hz BCV stimulation produced stronger noise in the vestibular system and improved the perception of self-motion.

Summary: An increasing number of brands are using political stances and ideological beliefs to convey their image to customers. Research shows that a persuasive appeal can be more effective when it provides cues incongruent with a brand's perceived political ideology. Specifically, conservative brands can improve consumer attitudes, purchase intentions, and brand choice by using dark skin-toned messaging cues, such as emojis, which are incongruent with conservative in-group preferences.

Summary: This study examines the differences in subjective visual vertical and horizontal deviation between unilateral acoustic neuroma patients and healthy young adults under varying degrees of static head tilt. The results demonstrate that patients with acoustic neuroma have higher absolute deviation values compared to healthy individuals, particularly when tilting their heads to the right. The size of the tumor does not appear to be significantly related to the extent of gravity sensing function damage.

However, there were no significant differences in visual heading perception between patients and controls.

Summary: This study proposes that the somatosensory system may implement multilateration to decode touch location on the body by estimating the relative distance between afferent input and body part boundaries. A simple feed forward neural network was shown to be able to implement this computation, and the computational signature of multilateration was identified in psychophysical experiments.

Summary: The study suggests that information from different sensory modalities can be integrated to improve perceptual precision. Both adults and adolescents tend to bias their localization towards the visual stimulus when presented with visual and tactile stimuli, especially when the stimuli are presented close to each other.

Summary: Referential pointing, a simple communicative behavior, is cognitively complex as it requires communicators to consider addressees' knowledge. This study examines how communicators' inferences about addressees' mental representation of the interaction space influence sensorimotor control of referential pointing. The findings suggest that participants generate communicative behaviors as required and integrate communicative and perspective-taking information hierarchically during sensorimotor control.

Summary: Behavioral studies have shown that humans take into account the effect of inertial acceleration on hand choice during body motion. This study used transcranial magnetic stimulation to investigate the integration of body motion information with hand selection. The results indicate that corticospinal excitability is influenced by body motion, suggesting that information about body motion deeply penetrates the motor system.

Summary: This study investigates the prior effect in multisensory integration of spatial orientation and finds that the Gaussian prior provides a better explanation for perceptual observations. The experiment also verifies that the natural statistics of head orientation have long tails, which can be quantified by a t-location-scale distribution.

Summary: The study examined the development of online reach control in infants aged six and eleven months. Infants reached for a toy while their hand position was tracked, and the toy was either stationary or unexpectedly displaced during the reach. The results showed that both age groups adjusted their reaching movements in the direction of the displacement, but the 11-month-old infants made adjustments within a single movement unit while the 6-month-olds required multiple movement units. This suggests that the reach control system develops a rudimentary replanning capacity by 6 months of age, which further develops into a more sophisticated mechanism by 11 months.

Summary: Contemporary motor control theories propose competition between multiple motor plans before the winning command is executed. This study shows that muscle activity during immediate response reach task is influenced by the nonchosen target and reveals different phases of directionally tuned activity, indicating an evolution in how the nonchosen target influences muscle activity.
