Divergent projections of projecting neurons of the inferior colliculus to the medial geniculate body and the contralateral inferior colliculus in the rat.
The present paper shows, by means of the combination of two fluorescent tracers, that a significant number of neurons of the three divisions of the inferior colliculus in the rat project to the contralateral inferior colliculus and the ipsilateral medial geniculate body. The topographic distribution of double-labeled cells depends on the location of injections in each case. According to the soma size and the dendritic stem, different neuron types may be distinguished. Our results suggest that the inputs that converge in individual neurons of the inferior colliculus can diverge again.
