Vestibular Cortex

The Vestibular Cortex is a part of the human brain that is involved in the processing of vestibular information. This information is crucial for maintaining balance and spatial orientation. The vestibular cortex is not a single, well-defined region but rather a collection of cortical areas that respond to vestibular stimulation.

Anatomy

The exact location and extent of the vestibular cortex are still a matter of debate among neuroscientists. However, several areas have been identified as part of the vestibular cortex, including the parieto-insular vestibular cortex (PIVC), the posterior insula, the retroinsula, the superior temporal gyrus, and parts of the inferior parietal lobule and somatosensory cortex.

Function

The vestibular cortex plays a crucial role in the perception of self-motion and spatial orientation. It receives input from the vestibular system, which detects changes in head position and motion. This information is then integrated with visual and somatosensory information to create a coherent perception of body position and movement.

The vestibular cortex is also involved in the control of eye movements and postural adjustments. It contributes to the vestibulo-ocular reflex, which stabilizes gaze during head movements, and the vestibulo-spinal reflex, which helps maintain balance.

Clinical significance

Damage to the vestibular cortex can lead to a variety of symptoms, including vertigo, dizziness, and problems with balance and spatial orientation. These symptoms can significantly impact a person's quality of life and ability to perform daily activities.
