Abstract
Electron microscopy of Golgi impregnated neurons has allowed the precise determination of the spatial relationships between identifiable profiles in optic cartridges and corresponding terminals in the medulla columns. Golgi-E.M. profiles can be correlated with profiles in normal electron microscopy. Structural contacts of cells in the lamina as well as their corresponding components in the medulla are described: functional contacts (synapses) known up to the present time are listed in figure 5 (polarities arrowed). Possibly structural contact may be indicative of functional intimacy, but this is still to be determined. At least three centripetal pathways (L1, L2, L3) convay information from R1 — R6 into the medulla. The other monopolars L4 and L5 appear to be intimate with endings of centrifugal cells from the medulla. The logic underlying the complexity of lamina organization seems to lie in the arrangement of feed-back and feed forward loops in parallel with the centripetal cells.
