“…To predict the eye movement while the user is in motion the dynamics of the vestibular-ocular system should be identified. The structure and parameters of the predictor has been constructed using the Hodgkin -Huxley vestibular activity model with Soto-Tikhonova-Alexandrov modifications [2] (n=2):…”

“…Advances in these technologies cannot be effectively studied without the understanding of the human visual perception system and associated physiological mechanisms. The study of galvanic stimulation as a method of reducing motion sickness in VR is relevant and has been carried out by a number of scientific groups, including Osaka University [1], Meritorious Autonomous University of Puebla, Lomonosov Moscow State University [2] and others.…”

“…This discrepancy is caused by several factors like delays due to tracking and rendering of the output image and physical limitations of the movement range of training systems. Consequently, attempts to overcome this problem covers several different research directions, including but not limited to dynamic motion systems, forecasting movement, and galvanic vestibular stimulation [3]. However, the problem can also be reversed, so that body reaction is used to estimate the accuracy of simulated motion.…”

Differential Neural Network-Based Nonparametric Identification of Eye Response to Enforced Head Motion

Dynamic motion simulators cannot provide the same stimulation of sensory systems as real motion. Hence, only a subset of human senses should be targeted. For simulators providing vestibular stimulus, an automatic bodily function of vestibular–ocular reflex (VOR) can objectively measure how accurate motion simulation is. This requires a model of ocular response to enforced accelerations, an attempt to create which is shown in this paper. The proposed model corresponds to a single-layer spiking differential neural network with its activation functions are based on the dynamic Izhikevich model of neuron dynamics. An experiment is proposed to collect training data corresponding to controlled accelerated motions that produce VOR, measured using an eye-tracking system. The effectiveness of the proposed identification is demonstrated by comparing its performance with a traditional sigmoidal identifier. The proposed model based on dynamic representations of activation functions produces a more accurate approximation of foveal motion as the estimation of mean square error confirms.

“…Galvanic vestibular stimulation (GVS) has been used to study postural changes due to vestibulospinal activation (Fujimoto et al., 2016, 2018; Inukai et al., 2018), the integrity of the vestibulo‐ocular pathway (Gensberger et al., 2016; Mackenzie & Reynolds, 2018), and spatial construction of body location (Nakamura et al., 2015; Utz et al., 2011; Volkening et al., 2014). GVS has also improved motor function in patients with Parkinson’s disease (Khoshnam et al., 2018; Lee et al., 2015), in vestibulopathy (Fujimoto et al., 2018; Wuehr et al., 2017) and may improve aerospace pilot performance (Sadovnichii et al., 2019; Vega et al., 2020). In cardiovascular studies, GVS has been recognized as a method to modulate cardiovascular function, like the autonomic cardiac improvement observed using 1/f noisy GVS, which increased covariance between baroreflex and HR in healthy subjects lying on an oscillatory tilt platform (Soma et al., 2003).…”

The study of cardiovascular function with galvanic vestibular stimulation has provided evidence on the neural structures that are involved in the vestibulo-autonomic reflex. This study determined if the effect on heart rate using galvanic vestibular stimulation persists after provoking a sympathetic response and if this response differs when using unilateral or transmastoid (bilateral) stimulation. We analysed heart rate and heart rate variability using unilateral and transmastoid galvanic vestibular stimulation combined with cardiovascular reflex evoked by postural change in 24 healthy human subjects. Three electrode configurations were selected for unilateral stimulation considering the anatomical location of each semicircular canal. We compared recordings performed in seated and standing positions, and with unilateral and transmastoid stimulation. With subjects seated, a significant transient decrease in heart rate was observed with unilateral stimulation. With transmastoid stimulation, heart rate decreased in both seated and standing positions. Average intervals between normal heartbeats recorded with stimulation resemble parasympathetic cardiac function induced by auricular vagal nerve stimulation. Our results indicate that unilateral stimulation does not eliminate the natural heart rate increase caused by orthostatic hypotension. In contrast, transmastoid stimulation provoked a transient reduction in heart rate, even when subjects were standing. These responses should be considered while performing experiments with galvanic vestibular stimulation and subsequent effects in cardiac regulation mechanisms.
