A doctor will look at a vertigo patient's rapid, uncontrollable eye movements—formally called nystagmus—to better understand its causes. When a patient is lying down with their head turned and their eyes spin in a certain position and stop it's likely a peripheral cause, but if the spinning doesn't stop or it changes direction it's more likely a central nervous system issue.

Some animals may speak because of duplicated connections in the brain

Neuroscience suggests that connections responsible for motion made during embryonic brain development—such as those connecting hearing and movement pathways that allow reactive motion when started—are duplicated and connected to the larynx in some animals. This allows some mammals and song-learning birds to speak, provided they have the necessary physiological structures.
