What is not typically a function of the vestibular system?

The vestibular system plays a crucial role in several key functions that are essential for maintaining our physical stability and awareness of our surroundings. One of its primary roles is balance maintenance, which is achieved through the detection of head position and movement in space. This system works closely with other sensory inputs, such as vision and proprioception, to help maintain equilibrium.

Spatial orientation is another important function of the vestibular system. It helps individuals determine their position in space relative to gravity, which is essential for navigating their environment effectively.

The vestibular system also aids in the coordination of visual input. When the head moves, the vestibular system helps stabilize vision by ensuring that the eyes can focus on objects without blurring, a process known as the vestibulo-ocular reflex.

However, memory processing is not a function of the vestibular system. Memory processing is primarily associated with other areas of the brain, such as the hippocampus and specific cortical regions that are involved in the encoding and retrieval of memories. Therefore, among the listed options, memory processing does not belong to the functions typically performed by the vestibular system.
