Final answer:
The vestibular information ends up in the primary somatosensory cortex, which is responsible for monitoring subjective measurements of the external world and self-movement.
Step-by-step explanation:
The vestibular information ends up in the primary somatosensory cortex. Neurons from the vestibular ganglion carry equilibrium information from the utricle, saccule, and semicircular canals to the vestibular nuclei, which then project to various targets in the brain, including the primary somatosensory cortex.
The primary somatosensory cortex is responsible for monitoring subjective measurements of the external world and self-movement. Lesions in the vestibular area of the somatosensory cortex can result in the perception of vertical objects as being tilted.
