Brain anatomy and summary of the knollenorgan pathway. A, Lateral view of brain of B. brachyistius. The nucleus exterolateralis sits between the valvula (VA) and the optic tectum (OT). The ELa is whiter than the ELp, because of its heavy myelin content. B, Summary of the knollenorgan pathway. Knollenorgan afferents project to the NELL, which in turn projects bilaterally to the ELa onto large and small cell types. The NELL also sends collaterals to the MV.C3, Cerebellar lobe 3; EGp, eminentia granularis pars posterior; ELa, nucleus exterolateralis pars anterior; ELL, electrosensory lateral line lobe; ELp, nucleus exterolateralis pars posterior; IL, inferior lobe; ll, lateral lemniscus; mm, meso-mesencephalic tract;MV, toral nucleus medialis ventralis;nALL, anterior lateral line nerve; NELLnucleus of the ELL; nPLL, posterior lateral line nerve;OB, olfactory bulb; op, optic nerve;SC, spinal cord; Tel, telencephalon;TL, torus longitudinalis; VA, valvula cerebelli. Scale bars: A, 1 mm; B, 250 μsec.
