The vestibular nuclei are a group of four nuclei located in the brainstem that play a crucial role in processing information related to balance and spatial orientation. They receive input from the inner ear's vestibular system, which detects head movements and position. This information is essential for maintaining balance and coordinating eye movements. These nuclei communicate with various parts of the brain, including the cerebellum and spinal cord, to help regulate posture and movement. They also send signals to the oculomotor system, which controls eye movements, ensuring that vision remains stable during head movements.
