What type of nystagmus occurs when a person is spun around or rotated rapidly?

Rotational Nystagmus is the correct answer because it specifically refers to the type of eye movement that occurs when a person is rapidly spun around or rotated. This phenomenon results from the stimulation of the vestibular system in the inner ear, which detects changes in motion and orientation. When the spinning stops, the fluid in the inner ear continues to move for a short time, leading to involuntary eye movements that are characteristic of rotational nystagmus. This type of nystagmus is essential in understanding the body's balance and coordination responses during and after rotational motion.

Post Rotational Nystagmus refers to the eye movements that occur after such spinning has stopped, while Caloric Nystagmus relates to the reaction of the eyes when warm or cold water is placed in the ear, testing the vestibular function. Optokinetic Nystagmus involves eye movements triggered by the movement of visual stimuli in the environment and is not directly related to the physical act of spinning. Each of these other types represents different conditions or stimuli that elicit specific eye movement reactions, but they do not directly describe the phenomenon occurring during the active rotation of the body.
