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.
Initiating the Response. Sensory nerve cells pass the perception of a threat, or stress, from the environment to the hypothalamus in the brain. Neurosecretory cells in the hypothalamus transmit a signal to the pituitary gland inciting cells there to release a chemical messenger into the bloodstream. Simultaneously, the hypothalamus transmits a nerve signal down the spinal cord. Both the chemical messenger and nerve impulse will travel to the same destination, the adrenal gland.
