Self-motion

FEELING OURSELVES MOVE: A TEAM EFFORT BY OUR SENSES

As you walk, bike, or drive down the street, your brain puts together (integrates) sensory information from different sources. It uses what you see, what you hear, and how your head and body move to help you judge your own movements. As you move, …

Visual–Vestibular Integration During Self-Motion Perception in Younger and Older Adults

Younger adults integrate visual and vestibular cues to self-motion in a manner consistent with optimal integration; however, little is currently known about whether this process changes with older age. Our objective was to determine whether older …

The impact of dual tasking on cognitive performance in a Parkinson's disease cohort with and without freezing of gait: An EEG and behavioral based approach

Freezing of gait (FOG) is a common disabling gait disorder in late stage Parkinson's disease (PD), which can lead to falls and loss of independence. To date, the mechanisms causing FOG are still unknown and no treatment has proven to be effective. In …

Optimal visual–vestibular integration under conditions of conflicting intersensory motion profiles

Passive movement through an environment is typically perceived by integrating information from different sensory signals, including visual and vestibular information. A wealth of previous research in the field of multisensory integration has shown …

Recalibration of inhibitory control systems during walking-related dual-task interference: A Mobile Brain-Body Imaging (MOBI) Study

Walking while simultaneously performing cognitively demanding tasks such as talking or texting are typical complex behaviors in our daily routines. Little is known about neural mechanisms underlying cortical resource allocation during such mobile …

Multisensory integration in the estimation of walked distances

When walking through space, both dynamic visual information (optic flow) and body-based information (proprioceptive and vestibular) jointly specify the magnitude of distance travelled. While recent evidence has demonstrated the extent to which each …

Mobile Brain/Body Imaging (MoBI): High-density electrical mapping of inhibitory processes during walking.

The present study investigated the feasibility of acquiring high-density event-related brain potential (ERP) recordings during treadmill walking in human subjects. The work builds upon recent studies testing the applicability of real-world tasks …

Neural correlates of oddball detection in self-motion heading: a high-density event-related potential study of vestibular integration

The perception of self-motion is a product of the integration of information from both visual and non-visual cues, to which the vestibular system is a central contributor. It is well documented that vestibular dysfunction leads to impaired movement …

The Role of Stereo Vision in Visual–Vestibular Integration

Self-motion through an environment stimulates several sensory systems, including the visual system and the vestibular system. Recent work in heading estimation has demonstrated that visual and vestibular cues are typically integrated in a …

Electrophysiological source analysis of passive self-motion

The neural processes underlying perception of motion are relatively unknown. In this study Electroencephalography (EEG) is used to investigate the neural responses to passive self-motion. A Stewart platform was employed to translate subjects forwards …
