Final answer:

The pathway of auditory signals through the brain is cochlea, auditory nerve, brainstem nuclei, inferior colliculi, medial geniculate nucleus, and finally the auditory cortex.

Step-by-step explanation:

The correct sequence that describes the pathway of auditory signals through the brain is: cochlea, auditory nerve, brainstem nuclei, inferior colliculi, medial geniculate nucleus, auditory cortex. After the activation of hair cells in the cochlea, the signals are sent through the auditory nerve to several nuclei in the brainstem. Here, location information from auditory stimuli is processed and integrated. The signals then travel to the inferior colliculi, which project to the medial geniculate nucleus of the thalamus. Finally, the auditory information is transmitted to the auditory cortex in the temporal lobe for further processing.
