Describe the various parts of the cochlear nucleus and the function of each part.
What will be an ideal response?
The auditory tract goes through the cochlear nucleus. The trapezoid body is attached to the cochlear nucleus. This body determines the direction of sound. Also in the cochlear nucleus are the subnuclei, which are sensitive to the onset and offset of tones at particular frequencies. Other cells in the cochlear nucleus perform a lateral inhibition function. These cells sharpen our detection of a particular frequency of incoming sound by inhibiting the response to nearby frequencies, either higher or lower.
