1. List the major components of the ear; note the role each plays in
hearing.
2. Draw from memory a cross section through the cochlea and label major
structures.
3. Imagine yourself walking from a hair cell on the basilar membrane
to the cochlear nuclei. What structures would you touch as you make your
way? (making a sketch will facilitate this exercise).
4. Walk through the central auditory pathway from cochlear nuclei to
cerebral cortex, listing the neural components in the order that you meet
them. Where are the obligatory synapses? Where are sites that enable information
to cross the midline?
5. Understand how displacements of the oval window are converted into
electrical impulses traveling down the cochlear nerve?
6. Understand the meaning of "difference in phase".
7. Understand why a lesion on one side of the brain does not give an
appreciable loss of hearing.
