Cortically Evoked Movement in Humans Reflects History of Prior Executions, Not Plan for Upcoming Movement

Human motor behavior involves planning and execution of actions, some more frequently. Manipulating probability distribution of a movement through intensive direction-specific repetition causes physiological bias toward that direction, which can be cortically evoked by transcranial magnetic stimulation (TMS). However, because evoked movement has not been used to distinguish movement execution and plan histories to date, it is unclear whether the bias is because of frequently executed movements or recent planning of movement. Here, in a cohort of 40 participants (22 female), we separately manipulate the recent history of movement plans and execution and probe the resulting effects on physiological biases using TMS and on the default plan for goal-directed actions using a timed-response task. Baseline physiological biases shared similar low-level kinematic properties (direction) to a default plan for …

Quantitative measures of the visually evoked sensation of body movement in space (Vection) using Electrovestibulography (EVestG)

Vection is defined as an illusory self-motion sensation induced in stationary observers that can be experienced in a real/virtual world. Vection, as a result of immersion in virtual reality (VR) environments, can subsequently lead to a sense of inability to maintain postural control and cause cybersickness symptoms. The multisensory integration of visual and vestibular (balance) information plays a vital role in vection. The etiology of vection perception, as well as, the vestibular response change while experiencing vection is poorly understood. This study explores vestibular response change following vection in 20 individuals (10 females, 26.45 ± 4.40 (SD) years). Vection was induced in participants using an immersive VR roller-coaster. The vestibular response was measured simultaneously using a noninvasive method called Electrovestibulography (EVestG). The detected field potentials and the time …

Electrovestibulography (EVestG) application for measuring vestibular response to horizontal pursuit and saccadic eye movements

Vestibular effects linked to eye movements have been extensively investigated, however, the effect of eye movements on the vestibular is relatively unknown. In this study, vestibular responses to horizontal pursuit and saccadic eye movements were examined in healthy individuals. Visual stimuli were presented to nineteen participants (27.7 ± 5.74 (SD) years, 11 female) using a virtual reality headset whilst the vestibular responses were simultaneously recorded using Electrovestibulography (EVestG). The average field potentials (FP) of three segments 1) prior to (Pre-Background), 2) during (Movement), and 3) after ceasing the visual stimulus (Post-Background) were extracted and the action potential (AP) area used as one feature. Both pursuit and saccadic eye movements resulted in a smaller average AP area during the Movement compared to Pre-Background (P = 0.002). Pursuit and saccadic eye …

Correlation between ocular and vestibular abnormalities and convergence insufficiency in post-concussion syndrome

The vestibular and oculomotor/visual systems are commonly affected in post-concussion syndrome (PCS). Convergence insufficiency (CI) is the most common ocular abnormality after concussion. Electrovestibulography (EVestG) is a relatively new non-invasive method that measures the peripheral vestibular responses; it has shown abnormal vestibular responses in a PCS. Here, we report the results of investigating the correlation between the vestibular and oculomotor systems in PCS population using EVestG and CI measures. Forty-eight PCS patients were tested using EVestG, out of which 20 also completed the Rivermead post-concussion questionnaire (RPQ). An EVestG feature (Field Potential (FP)-area) was extracted from the stationary part of the EVestG signals. A neuro-ophthalmologist (author BM) measured participants’ CI at near vision using cross-cover examination and a prism-bar. Results indicate: (1 …

Differences between physical vs. virtual evoked vestibular responses

Electrovestibulography (EVestG), a technology purported to measure vestibular activity at the vestibular periphery, was used to compare the vestibular responses to two sensory inputs: (1) back-forward physical tilt (with eyes-open and eyes-closed) and (2) virtual reality replica of the back-forward tilt (eyes-open, physically static). Twenty-seven healthy participants (10 females) were tested. From each of the EVestG recordings, two feature curves: (1) average field potential (FP), and (2) distribution of time intervals between the detected FPs were extracted. For the eyes-closed physical tilt, except for the background segment, the FP response curve was generally wider compared to that evoked during the virtual replica tilt (p < 0.05). Moreover, the eyes-closed physical tilt produced longer time intervals between FP’s compared to the virtual stimulus. For this measure, for the background segment, the eyes …
