Figure 14. Semi-schematic diagram of primary visual centers in the CNS of Phidippus (after Hill 1975, 2006). Dorsal view of the left side, based on examination of serial silver and Masson Trichrome sections. The first link between information received by the lateral eyes and the anterior medial eyes is in the protocerebrum. The solid black bars indicate groups of fibers entering the protocerebrum. Fibers leading from the primary neuropiles of the lateral eyes (AL1 and PL1) lead to either the synaptic layer (lame glomerulee) of the corpus pedunculatus (pedunculate body), or to the lateral eye neuropile and lateral eye tract. Large, distinctive fibers of the primary neuropile of the posterior medial eyes (PM1) join similar fibers originating with a small neuropile (ALx) associated with the primary neuropile of the anterior lateral eye (AL1). These large fibers enter the protocerebrum as a distinctive tract (lft). Several important groups of neuron somata are shown. A bridge (fiber tract) connects the left and right corpora pedunculata. See Figure 15 for a more current view.
