The anuran superficial reticular nucleus: evidence of homology with nuclei of the lateral lemniscus.
The superficial reticular nucleus (SR) of ranid frogs is part of a lateral cell column extending from the isthmus to the rostral tegmentum. The caudal part of this nucleus receives input from lower brainstem auditory nuclei and projects bilaterally to the torus semicircularis. On the basis of its position, connections, and sensitivity to acoustic stimuli, the caudal SR appears to be homologous to all or part of the mammalian nuclei of the lateral lemniscus.
