Assessing hearing through the pupil dilation response (PDR) to sound offers a non-invasive alternative to traditional audiometry, particularly useful in individuals unable to provide behavioral responses. However, reliable detection of sound-evoked PDRs is limited by variability in pupil size and the risk of false positives (Type I Errors). This study investigated whether pseudo-random variation of sound frequency and amplitude enhances the correspondence between PDR detection and sound perception in normal-hearing subjects. To improve reliability, epoch...Mehr anzeigen

Traditional methods for evaluating spatial neglect or milder lateralized visuospatial attention deficits have been criticized for limited ecological relevance, narrow scope, and overly simplistic design. To address this, we introduce a new version of the Executive Performance in Everyday LIving (EPELI) virtual reality task. In the EPELI, participants perform cognitively demanding everyday chores in a home-like environment, while precise behavioral data capturing diverse aspects of visual attention is recorded. Fourteen healthy controls and ten right-side...Mehr anzeigen

The human eyes are continuously adjusting refractive power, vergence angle, and pupil diameter when exploring the visual environment. Adjustment errors in these visuomotor functions reduce the stimulus contrast driving ON and OFF retinal pathways, and ON retinal pathways become weaker, slower, and less sensitive in refractive disorders such as myopia. Here, we demonstrate that, in addition to these sensory deficits, myopes also have deficits in visuomotor functions driven by ON and OFF pathways during lens accommodation. We show that humans with myopia h...Mehr anzeigen

BackgroundMobility in people with Parkinson’s disease (PwPD) is strongly context-dependent. Clinic-based assessments provide only brief snapshots under controlled conditions and may not reflect everyday functional capacity. Wearable sensors enable continuous free-living monitoring, yet most studies use unimodal signals and simple threshold-based walking detection. Multimodal sensing, combining surface electromyography (sEMG) with inertial measurement units (IMUs), can offer a more complete picture of mobility in Parkinson’s disease (PD). Therefore, devel...Mehr anzeigen
