Question

Why does the ipsilateral and contralateral input from the AVCN land at different parts of the axon to the MSO?

a) To create a delay for sound localization
b) To prevent signal interference
c) To balance auditory processing
d) To improve frequency discrimination

Answer 1

The ipsilateral and contralateral input to the MSO from the AVCN lands at different parts of the axon to prevent signal interference and ensure accurate sound localization.

Step-by-step explanation:

Sound localization in the auditory nuclei of the brain stem is achieved by calculating the interaural time difference and interaural intensity difference. The ipsilateral and contralateral input from the anteroventral cochlear nucleus (AVCN) lands at different parts of the axon to the medial superior olive (MSO) to prevent signal interference. This ensures that the MSO can accurately process and compare the timing and intensity differences in sound stimuli received at each ear for accurate sound localization.
