Correct Answer
A. Spiral ganglia --> cochlear nucleus --> lateral lemniscus---> superior olivary nuclei & inferior colliculus ---> brachium of inferior colliculi ---> MGN ---> auditory cortexExplanation
The correct sequence of auditory information starts with the spiral ganglia, which receive auditory signals from the cochlea. These signals are then transmitted to the cochlear nucleus, where they are processed further. From the cochlear nucleus, the signals travel to the lateral lemniscus, which is a pathway in the brainstem that carries auditory information. The lateral lemniscus then projects to the superior olivary nuclei and inferior colliculus, which are involved in sound localization and processing. The signals continue to the brachium of the inferior colliculi, which is a bundle of nerve fibers that connects the inferior colliculus to other parts of the brain. From there, the signals are relayed to the medial geniculate nucleus (MGN), which acts as a gateway to the auditory cortex, where sound perception occurs.Rate this question:
