AI Article Synopsis
- The study explores the role of the sacculocolic reflex pathway in the development of seasickness, with a focus on asymmetrical function of the otolithic organ.
- It compares cervical evoked myogenic vestibular potential (cVEMP) results between 15 sailors with seasickness and 15 sailors without it.
- Findings show that sailors with seasickness had shorter p13 and n23 wave latencies and higher interaural wave amplitude asymmetry ratios, suggesting a physiological basis for their condition.
Article Abstract
There are different theories cited as the cause of Motion Sickness. Asymmetrical otolithic organ function is one of the etiology theories of motion sickness. In our study, the aim was to reveal whether there is a cause originating from the sacculocolic reflex pathway in the physiopathology of seasickness. The patient group included 15 man sailors with diagnosis of seasickness and the control group included 15 man sailors without seasickness in our study. Cervical evoked myogenic vestibular potential (cVEMP) findings were compared between the groups. In the right and left ears of sailors with seasickness, the mean latencies of the p13 and n23 waves at 100, 95, and 90 dB normal hearing level (nHL) levels were found significantly shorter than in the control group ( < 0.05, for all). In the seasickness group, cVEMP interaural wave amplitude asymmetry ratio at 100 nHL level were found significantly higher than the control group ( = 0.001). The findings of our study indicated that there may be reasons arising rom the sacculocolic reflex pathway in the pathophysiology of seasickness.

Article Synopsis
- The working conditions for submarine crews are challenging due to limited space, extreme temperatures, and other stressors, which negatively impact mental health.
- American psychologists have developed successful psychological resilience training for military personnel, but more research is needed in this area, particularly for submarine crews.
- A study involving 121 soldiers showed that active psychological regulation interventions significantly improved various psychological measures, highlighting the need for such programs in confined maritime environments.

Background: Motion sickness, is the onset of a series of clinical signs when travelling in a means of locomotion. Boats are the most common source of kinetosis, causing seasickness. Although this condition is often benign, it can severely affect the quality of life of seafarers, as well as the quality of their work.

Introduction: Vection is a stationary individual's illusory experience of self-motion. This illusory self-motion is operationally important for aviation, particularly military aviation, since vection is a dramatic example of spatial disorientation (SD), which is an individual's failure to correctly sense the aircraft's position, motion, and/or attitude with respect to the fixed coordinate system of the Earth's surface and its gravitational vertical. Notably, SD is a major cause of fatal aviation mishaps, and the visual system is particularly prone to provoking vection.

MdDS is syndrome of oscillating vertigo following cessation of passive motion. The pathogenesis of this disorder is not well understood, but functional imaging studies suggest cortical connectivity dysfunction in feedback loops of the vestibulo-ocular system and visuo-spatial system. Patients go through multiple appointments and often specialist referrals before being diagnosed.
