Afferent connections of the inferior colliculus in the albino mouse.

We have studied the afferent connections of the inferior colliculus of the albino mouse. Our results show: First, the afferent connections of the inferior colliculus in the mouse are similar to those of other species, however, some differences exist. Second, there is a different projection pattern to the dorsal cortex and the central nucleus of the inferior colliculus; the dorsal cortex receives fibers essentially from auditory centers, while the central nucleus also receives afferents from other structures not related to the auditory system. Third, an interesting parallel may be established between the connections of the inferior colliculus and those of the superior colliculus.
