Auditory System Anatomy - Neurophysiologic Considerations. 1  The complex chain of nerve cells in the auditory system helps to process and relay auditory information, encoded in the form of nerve impulses, directly to the highest cerebral levels in the cortex of the brain. To some extent, different properties of the auditory stimulus are conveyed along distinct parallel pathways.
Ascending tracts conduct impulses up the spinal cord to the brain; descending tracts conduct impulses down the cord from the brain. The four major ascending tracts are the lateral spinothalamic, the ventral spinothalamic, the fasciculi gracilis and cuneatus, and the spinocerebellar.ny one of the ascending (sensory) and descending (motor) pathways for sensory or motor nerve impulses that is found in the white matter of the spinal cord.
