(a) Reconstruction of the Pe1 neuron within the protocerebrum of the honeybee from a cell filled intracellularly with lucifer yellow. The Pe1 neuron enters the MB at the border from the β-lobe (β-L) to the peduncle (Pe) and arborizes extensively in the peduncle. The soma is located below the anterior brain surface and gives rise to a neurite that arborizes in the median contralateral protocerebral lobe (mPL). In the protocerebral lobe one branch courses lateral, gives rise to arborizations in the lateral protocerebral lobe (LPL), and terminates in the lateral horn (LH). (MC) Median calyx; (LC) lateral calyx; (li) lip; (co) collar; (br) basal ring; (OL) optic lobe. Scale, 100 μm. (d) Dorsal; (l) lateral; (m) median. (b,c) Magnified parts of the Pe1 neuron in the posterior (b) and more anterior peduncle (c). Note the spiny processes along the course of the dendrites. Scale in b and c, 10 μm.
