Austin experiences motion sickness due to conflicting information from which two senses?

Austin experiences motion sickness primarily due to conflicting information from the vestibular system and visual input. The vestibular system, located in the inner ear, is responsible for detecting motion, orientation, and balance. When a person is in a moving vehicle, the vestibular system registers the movement. However, if the visual information from the eyes does not match this sense of movement—such as when one reads a book while the vehicle is in motion—this discrepancy creates a conflict in sensory information. The brain struggles to reconcile these differing messages, which can lead to symptoms of motion sickness such as dizziness and nausea.

This relationship underscores the importance of coherent sensory input for maintaining balance and spatial awareness. When sensory systems provide inconsistent information, the brain's ability to interpret the environment accurately is compromised, leading to discomfort.
