the results support several conclusions : ( 1 ) high to low frequencies are represented in a dorsocaudal to ventrorostral sequence in a-i , ( 2 ) intrinsic connections in a-i are more pronounced along isofrequency contours , ( 3 ) the pattern of connections between a-i and adjoining cortex suggests that this surrounding auditory cortex contains at least two tonotopically organized fields and possibly one or more additional auditory fields , ( 4 ) callosal connections of a-i are largely between parts of a-i matched for frequency representation , ( 5 ) thalamic connections of a-i include topographic connections with the ventral division of the medial geniculate complex ( mgv ) and more diffuse connections with the medial ( mgm ) and dorsal ( mgd ) divisions of the medial geniculate complex and the suprageniculate nucleus ( sg ) , and ( 6 ) a-i projects bilaterally to the dorsal cortex of the inferior colliculus .
