      This massive pathway terminates in Brodman's area 17, the primary visual cortex. In the case of the auditory modality, the MGB receives auditory input from the inferior colliculus and gives rise to the acoustic radiation that terminates in Brodman's areas 41 and 42, the primary auditory cortex.
