Causes of  Motion sickness:

There are various theories to explain the cause of the motion sickness.

Sensory conflict Theory

Complete adequate theory of motion sickness is not presently available but contemporary sensory conflict theory. According to this theory when the mind presents the mind with two incongruous states of motion. Based on this theory the cause of terrestrial motion sickness is the opposite of the cause of space motion sickness. The formes occur when one perceives visually that one’s surroundings are relatively immobile while the vestibular systems reports that one’s body is in motion relative to it’s surroundings.

Neural Mismatch

A variation of the sensory conflict theory is known as neural mismatch, implying occurring between ongoing sensory experience and long term memory rather than between components of the vestibular & visual system.

As when we travel in a bus or any vehicle that vestibular nerve system sends signals to the body in no motion. As the visual system involves that our body can senses that the body is in motion.

Due to neuronal senses mismatching the CTZ(Chemoreceptor trigger zone) trigger is activated. Due to activation of CTZ it involves emesis thus this cause motion sickness.

Dizziness due to Spinning

When one spins and stops suddenly, fluid in the inner ear continues to rotate causing a sense of continued spinning while one’s visuals system no longer detect motion.

Treatment
