The vestibular system plays an important role in intersensory interactions and gravitation is a natural stimulus for its receptors. Weightlessness alters the input signals of the otoliths and their effect on the pattern and dynamics of changes in the vestibular function (VF), which is accompanied by development of space adaptation syndrome (SAS) and space motion sickness (SMS). These changes occur both during the spaceflight (SF) and after returning to Earth, but the mechanisms of their… Expand
INFLUENCE OF A 30-DAY SPACEFLIGHT ON THE STRUCTURE OF MOTONEURONS OF THE TROCHLEAR NERVE NUCLEUS IN MICE
TLDR
The main role in the adaptation of the trochlear nucleus to microgravity conditions, apparently, belongs to the dendrites of motoneurons, which rearrange their structure and function to enhance the flow of sensory information. Expand
Influence of a 30-day spaceflight on the structure of motoneurons of the trochlear nerve nucleus in mice
TLDR
It was shown that the dendrites of motoneurons in the nucleus of the trochlear nerve significantly reorganized their geometry and orientation under microgravity conditions, and the number of dendritic branches was increased, possibly in order to amplify the reduced signal flow. Expand

Vestibular function and sensory interaction in space flight.
TLDR
The vestibular system and vestibulo-visual interaction were examined in 11 astronauts by the electrooculographic method during short- and long-term flights and showed enhanced spontaneous vertical nystagmus, and disorders of tracking of vertical and diagonal movements of the stimulus which improved after active head movements. Expand
Space motion sickness and motion sickness: symptoms and etiology.
TLDR
V Vestibular biomechanics that occur during weightlessness coupled with theoretical assertions regarding human evolution have led to a two-component model of SMS that may initiate a protective mechanism that may produce symptoms that discourage activity. Expand
Studies of the horizontal vestibulo-ocular reflex in spaceflight.
TLDR
It is concluded that at this stimulus frequency, VOR gain is unaffected by spaceflight, and any minor individual changes do not seem to contribute to space motion sickness. Expand
Gaze control and vestibular-cervical-ocular responses after prolonged exposure to microgravity.
TLDR
Examination of visual tracking with the head in a fixed position was performed in 26 Russian ISS cosmonauts before and after a prolonged spaceflight and revealed disturbances in precision ofVisual tracking and adoption of the new tracking strategy substantially prolong the period required to acquire, recognize, and to fixate gaze on the target.

Decreased otolith-mediated vestibular response in 25 astronauts induced by long-duration spaceflight.
TLDR
This work studied the otolith-mediated responses elicited by centrifugation in a group of 25 astronauts before and after 6 mo of spaceflight, finding a statistically significant decrease of the OCR response upon return. Expand
Vestibular Function after Repeated Space Flights
TLDR
It is shown that the repeated stay in the long SF leads to a considerable statistically significant reduction in the de-adaptation period. Expand

TLDR
It is suggested that VOR gain is reduced initially, but that rapid compensatory mechanisms restore it to normal within minutes of reaching weightlessness, even though this process may not protect against the development of motion sickness. Expand
Evaluation of the torsional VOR in weightlessness.
TLDR
Preliminary results indicate alterations in the torsional VOR under zero-g conditions, suggesting an adaptive modification of the tORS gain over the course of the 6-day orbital flight. Expand
Static torsional otolith–cervical–ocular reflex after prolonged exposure to weightlessness and a 7-day immersion
TLDR
It was demonstrated that minimization of the support and proprioceptive afferentation may result in an inversion or absence of the static torsional OCOR and the development of a positional nystagmus with an inverted reflex. Expand
