Abstract Photomicrograph of a Golgi cell from the valvular ridge of the cerebellum of a mormyrid fish ( Gnathonemus petersii ). The cell was filled with neurobiotin in a transverse slice of the valvular ridges and the neurobiotin was revealed with red fluorescent dye. Nissl counterstaining is shown in green. The cell was photographed in a slice of 200 μm using a confocal laser scanning microscope. The cell body is located in the basal region of the ganglionic layer. Several smooth primary dendrites arise from the molecular side of the soma and give off secondary and tertiary branches irregularly. The dendrites become thinner and smoother as they extend further into the molecular layer. The thick axon arises from the granular layer side of the soma and projects into the granular layer where it branches extensively. En passant synaptic boutons are visible on the axonal branches. The large ball‐like ending of the main axon is probably a cut branch of the axon at the edge of the slice. J. Comp. Neurol. 509: 449‐473, 2008. © 2008 Wiley‐Liss, Inc.
