In many vertebrates parallel processing in topographically ordered maps is essential for efficient sensory processing. In the active electrosensory pathway of mormyrids afferent input is processed in two parallel somatotopically ordered hindbrain maps of the electrosensory lateral line lobe (ELL), the dorsolateral zone (DLZ), and the medial zone (MZ). Here phase and amplitude modulations of the self‐generated electric field were processed separately. Behavioral data indicates that this information must be merged for the sensory system to categorically distinguish capacitive and resistive properties of objects. While projections between both zones of the ELL have been found, the available physiological data suggests that this merging takes place in the midbrain torus semicircularis (TS). Previous anatomical data indicate that the detailed somatotopic representation present in the ELL is lost in the nucleus lateralis (NL) of the TS, while a rough rostrocaudal mapping is maintained. In our study we investigated the projections from the hindbrain to the midbrain in more detail, using tracer injections. Our data reveals that afferents from both maps of the ELL terminate in a detailed somatotopic manner within the midbrain NL. Furthermore, we provide data indicating that phase and amplitude information may indeed be processed jointly in the NL. J. Comp. Neurol. 524:2479–2491, 2016. © 2016 Wiley Periodicals, Inc.
